I need a sleep tracker mat that goes under the mattress and integrates with home automation.

If under-mattress + home automation are your two key requirements, I’d put the Withings Sleep at the top of the list.

• Withings Sleep Mat - $199.95 (Paceline)

Best fit: Withings Sleep

• Goes directly under the mattress and works with spring, foam, latex, and memory-foam mattresses. It’s been tested with mattresses 4–15 inches thick.
• Tracks sleep stages, sleep duration, heart rate, snoring, breathing disturbances, and movement.
• Wi-Fi connected, so it doesn't require you to wear anything or sync manually each morning.
• It has an explicit smart-home/IFTTT integration—for example, getting into bed can trigger lights or thermostat changes, and getting up can trigger other automations.
• If you're using Home Assistant, there's now an official Withings integration. It can expose sleep-related sensors and receive updates via Withings webhooks.
• Current Withings US pricing is about $199.95.

One important distinction

If by "home automation" you mean Home Assistant specifically, Withings is considerably more attractive than many consumer sleep mats. Home Assistant's Withings integration can give you sleep data that you can use in automations—for example:

If sleep state = awake → turn on hallway lights at low brightness If someone gets into bed → turn off downstairs lights If sleep duration was poor → adjust morning lighting/routine The Withings API is also documented, so there's a path to building your own integration if the standard Home Assistant entities aren't enough.

I would choose Withings over Eight Sleep for your particular requirement unless you also want active mattress temperature control. Eight Sleep's Pod is much more of a smart climate-control system and substantially more expensive.

If you tell me whether you're using Home Assistant, Apple Home, Google Home, Alexa, Hubitat, or SmartThings, I can narrow this down to the best 2–3 under-mattress sensors that can actually trigger automations in your setup.

The gold standard—and practically the only mainstream consumer option—for an under-mattress sleep tracking mat with home automation capabilities is the Withings Sleep Tracking Mat Go to product viewer dialog for this item. (also known as Withings Sleep Analyzer).

Withings Sleep Tracking Mat

• How it works: It is a slim, non-intrusive pneumatic sensor mat that slips right under your mattress (between the mattress and the bed base or box spring). It works with mattress thicknesses between 4 to 15 inches.
• What it tracks: Deep, light, and REM sleep cycles, sleep duration/interruptions, continuous heart rate, snoring, and breathing disturbances (signs of sleep apnea).
• Home Automation Integration:
  • IFTTT Support: Native, out-of-the-box IFTTT integration allows you to trigger automations like turning off lights/adjusting the thermostat when you get into bed, or triggering morning routines when you get out.
  • Advanced/Local Control (Home Assistant): If you use a local smart home platform like Home Assistant , you can integrate Withings via its official API integration. This exposes "in-bed" and "out-of-bed" states as well as sleep scores directly into your local automation ecosystem, allowing you to build reliable presence detection and good-night/good-morning routines.
• Where to buy: Available via retailers like Crutchfield or cpap.com.

Are you trying to integrate this with a specific smart home platform like Home Assistant, Apple HomeKit , or Google Home , so we can map out the exact automation triggers you need?

Yes — if under-mattress + sleep tracking + home automation are the priorities, I’d start with Withings Sleep.

• Withings Sleep Analyzer - $175.18 (IoThings.store)

Best fit: Withings Sleep

• Goes under the mattress: It’s a thin pneumatic sensor designed for one-time installation underneath the mattress. It works with spring, foam, latex and memory-foam mattresses around 4–15 inches thick.
• Tracks actual sleep: sleep duration, sleep onset/wake time, sleep stages, heart rate, breathing, movement, snoring and sleep score.
• Home Assistant: There is an official Home Assistant Withings integration, which can expose sleep-related data and an in-bed sensor for automations.
• IFTTT: Withings also officially supports IFTTT, so you can trigger things such as lights and thermostat changes when you get into or out of bed.
• No wearable: You don't need to wear a watch or ring to bed.

One caveat: the Home Assistant integration is cloud-based and requires Withings developer/API setup. The sleep presence sensor also relies on webhooks; Home Assistant Cloud/Nabu Casa can simplify that networking requirement. Home Assistant There is also a recently reported 2026 issue involving some Sleep Analyzer units not exposing all sleep entities in Home Assistant, so I'd consider that before buying specifically for detailed HA automations.

Other option

• Eight Sleep Pod 4 - $2,599.00 (Eight Sleep)

Eight Sleep is much more elaborate: it combines sleep/health tracking with active temperature control, but it's a much more expensive smart-bed system, rather than a simple sensor mat.

If you tell me which home-automation platform you use (Home Assistant, SmartThings, Hubitat, Alexa, Apple Home, etc.), I can narrow it down to the best options and specifically check what sleep/bed-presence data can be used as automation triggers.

When it comes to non-wearable, under-mattress sleep tracking mats that tie into home automation, the undisputed industry standard is the Withings Sleep Tracking Mat Go to product viewer dialog for this item. (often sold as the Withings Sleep Analyzer Go to product viewer dialog for this item. in Europe).

The market for standalone under-mattress pads is quite niche because many smart home users opt for pressure-mat DIY sensors or smart bed toppers (like Eight Sleep), but Withings remains the go-to plug-and-play choice for slipping under an existing mattress.

The Gold Standard Option: Withings Sleep Tracking Mat

• How it works: It’s a slim, pneumatic fabric pad that slips horizontally underneath your mattress at chest level. It plugs into a USB power brick and connects to your home network via Wi-Fi.
• What it tracks: Sleep cycles (deep, light, REM), continuous heart rate, snoring, and breathing disturbances (useful for detecting sleep apnea signs).
• Home Automation Integration:
  • IFTTT: Native support lets you build applets (e.g., If I get into bed -> turn off the smart lights and lower the thermostat).
  • Home Assistant: Can be integrated via the official Withings integration (though getting real-time "in-bed" presence state reliably often requires configuring webhooks in Home Assistant).
  • Alexa / Google Assistant: Basic routine triggers are supported, though local-control options are limited since it syncs via the cloud.

Important Considerations Before Buying

• Mattress Thickness: It works best with mattresses between 4 to 15 inches thick. Very thick memory foam or hybrid mattresses can dampen the pneumatic sensor's ability to accurately pick up heart rate and breathing.
• Bed Frame Type: It requires a solid flat surface or closely spaced slats under the mattress to properly capture ballistocardiography (movement, heartbeats, respiration). Thick flexible arch-slats can distort readings.
• Single-Side Monitoring: Each mat tracks one side of the bed. If you want to track both partners, you need two separate mats and two separate accounts.

Community Experiences

Users leveraging these mats for automation frequently share tips on maximizing reliability:

“I bought the Withings Sleep Analyzer hoping to use the ‘in bed’ entity in my home automations. Unfortunately, after following the official integration guide, that entity simply didn't show up anywhere.”

“After some research (and quite a few failed attempts), I finally managed to make it work! Here's everything I did — I can't guarantee every step is ‘the official’ way, but it worked perfectly for me.”

If your priority is a physical mat under the mattress + useful sleep data + home automation, I’d look at these in this order:

1. Withings Sleep — best overall fit

• Withings Sleep - $276.49 (kate-minimalist)

The Withings Sleep is specifically designed to sit under the mattress and tracks sleep duration, sleep stages, heart rate, snoring, and bed occupancy.

The big advantage for automation is Home Assistant support. Home Assistant has an official Withings integration, which can expose sleep-related sensors and other Withings data to your automations.

You can therefore build things like:

• Bed occupied → turn off bedroom lights
• Bed occupied after 10 PM → set thermostat to nighttime temperature
• Wake detected → gradually turn on lights
• Sleep detected → arm the house
• Out of bed in the morning → start coffee / open blinds
• Use sleep data in dashboards and automations

There is one caveat: the Home Assistant integration is cloud-based, using the Withings API rather than a completely local connection.

2. Withings Sleep Analyzer

• Withings Sleep Analyzer - $175.05 (IoThings.store)

This is essentially the more advanced version of the same concept. It goes under the mattress and uses a pneumatic sensor to measure breathing, heart rate, and movement.

Important for you in the U.S.: Withings currently distinguishes its products by region. The Sleep Analyzer is listed for EU/Australia/UK, while the U.S. product is Withings Sleep.

3. If you want automation more than sleep analytics

There are dedicated under-mattress presence sensors designed primarily for smart-home automation. These can be preferable if what you really want is "is someone in bed right now?" rather than detailed sleep staging.

For example, an ESPHome/Home Assistant-based sensor can give you much more immediate/local occupancy information than a cloud sleep tracker. The tradeoff is that you generally won't get Withings-level sleep analysis.

My recommendation

If you're already using Home Assistant, I'd buy the Withings Sleep and integrate it into Home Assistant. It's the best balance of:

under-mattress form factor → good sleep tracking → bed occupancy → established Home Assistant integration.

If you tell me which home-automation system you use (Home Assistant, SmartThings, Hubitat, Apple Home, Alexa, Homey, etc.), I can narrow this down to the best 2–3 mats that actually integrate with your system, including whether the integration is local or cloud-based.

Finding a reliable under-mattress mat that tracks deep/REM sleep and ties natively into a smart home is tricky because the market is split into two categories: medical-grade/wellness sleep mats (which have poor native smart home APIs) and robust bed presence sensors (which track occupancy/presence rather than detailed sleep stages).

The best options available depending on whether you prioritize deep sleep analytics or fast local home automation include:

Top Under-Mattress Options

• Withings Sleep Tracking Mat
  • What it does: Slides under your mattress (4 to 15 inches thick) and plugs into USB. It passively tracks sleep cycles (deep, light, REM), heart rate, continuous snoring, and breathing disturbances.
  • Home Automation Integration: It does not have a direct local API or native Matter/HomeKit integration. Instead, it relies on IFTTT applets. You can trigger routines like dimming lights when you get into bed or turning up the thermostat when you get up.
  • Best for: Someone who wants actual sleep tracking metrics (heart rate, breathing, sleep stages) without wearing a ring or watch, and doesn't mind routing automations through IFTTT.
• Elevated Sensors Bed Presence MK1 Go to product viewer dialog for this item.
  • What it does: A long, force-resisting sensor strip that mounts discreetly between your mattress and your bed slats or box spring.
  • Home Automation Integration: Preloaded with ESPHome for a native, lightning-fast, local plug-and-play setup with Home Assistant . It can detect left/right occupancy individually.
  • Best for: Pure, ultra-reliable bed occupancy detection (knowing precisely when you get in or out of bed to turn off/on lights, lock doors, or arm security), rather than logging your REM cycles.
• • What it does: Another textile-based pressure sensor pad that slides under the mattress.
  • Home Automation Integration: Connects directly via Wi-Fi/ESPHome to Home Assistant , which can then expose triggers to Google Home or Apple HomeKit.
  • Best for: Local-only, privacy-focused presence automations without cloud dependencies.

Real User Experiences

“The Withings sleep mat Go to product viewer dialog for this item. has been 100% reliable for me and my wife. We use it to turn on the bedroom ceiling fan when we are sleeping and our room is over a certain temperature.”

“Works for me as well, through a very thick mattress it even can detect my heartbeat. Very sensitive.”

To help narrow down the best choice, tell me:

• What smart home platform are you running (e.g., Home Assistant, Apple HomeKit, Google Home)?
• Do you care more about health metrics (sleep stages, heart rate) or presence triggers (turning off lights the second your head hits the pillow)?

Yes. If home automation is the priority, I’d narrow it to these:

Best fit: ASC SlumberTek

This is probably the closest match to what you described. It’s an under-mattress pressure/presence mat specifically designed for automation, rather than primarily a health tracker.

• Works with Home Assistant today
• Can trigger lights, HVAC, security, “night mode,” morning routines, etc.
• USB-connected
• No camera, microphone, or wearable
• Can expose the bed as an automation trigger based on whether you're in bed
• Home Assistant can then bridge it to HomeKit, Alexa, Google Home, and SmartThings.

I'd choose this if your main goal is:

“When I get into bed, do X; when I get out of bed, do Y.”

Best for actual sleep tracking: Withings Sleep

Withings Sleep Analyzer

$173.55

The Withings mat sits under the mattress and tracks sleep stages, heart rate, breathing, interruptions, and snoring. It's designed for a one-time installation and works with mattresses roughly 4–15 inches thick.

The big advantage for automation is that Home Assistant has an official Withings integration. It can expose sleep-related sensors and a sleep binary sensor for automations.

The catch: it's cloud-based, and getting the full Home Assistant integration working requires the Withings developer/API setup and, for the sleep binary sensor, a reachable HTTPS webhook.

I'd choose this if your goal is:

“I want real sleep data and want to use it in Home Assistant.”

Emfit QS — more serious sleep/biometric tracking

Emfit makes under-mattress ballistocardiography sensors that can track things like heart rate, HRV, respiration, movement and bed events. Its cloud API can push sleep summaries and live data to your own endpoint.

There has also been a Home Assistant custom integration for Emfit QS, although I'd consider this a more DIY route than SlumberTek or Withings.

My ranking for your use case

One important distinction: SlumberTek is a bed-presence/automation sensor, whereas Withings and Emfit are actual sleep-monitoring systems. If you tell me whether you're running Home Assistant, Hubitat, HomeKit, SmartThings, or something else, I can narrow this down to the best 2–3 options and check current US pricing and availability.

The primary, gold-standard consumer product that fits this exact description is the Withings Sleep Tracking Mat Go to product viewer dialog for this item. (also sold in some regions as the *Withings Sleep Analyzer Go to product viewer dialog for this item. *).

Watch this overview of the Withings Sleep Pad to see how it installs under the mattress and monitors your sleep without wearables:

24s Withings Sleep Pad - Full Sleep Tracking with Zero Wearables 3.7K views  · 1 year ago YouTube · JDubb

The Main Option: Withings Sleep Tracking Mat

• How it works: It is a thin, fabric-covered pneumatic sensor pad that slides directly under your mattress (at chest/heart level) between the mattress and your bed platform, slats, or box spring. It plugs into a standard USB wall adapter and requires no charging or wearing of devices.
• What it tracks: Continuous sleep cycles (deep, light, REM), snoring, breathing disturbances, and resting heart rate.
• Home Automation Integration:
  • IFTTT: Officially supports IFTTT (If This Then That), allowing you to create simple applets like turning off your house lights when you get into bed or adjusting your smart thermostat when you wake up.
  • Home Assistant: Can be integrated into local/advanced smart home setups via the official Withings integration (though it relies on cloud webhooks to update the "in-bed" binary sensor state).

Alternative DIY / Local Control Approach

If you want absolute local control (bypassing cloud dependencies) for pure bed-occupancy automation rather than deep health tracking:

• Smart Bed Presence Sensors: Enthusiasts often use custom or niche pressure-sensitive force-resisting sensor strips (such as those integrated with ESPHome like the Bed Presence MK1 Go to product viewer dialog for this item. or custom piezoelectric/pneumatic DIY setups) wired to local microcontrollers.
• How they integrate: They mount under the mattress or slats and connect directly and locally via Zigbee or ESPHome into platforms like Home Assistant for instant, rock-solid presence and sleep-state triggers without relying on Withings' cloud servers.

Are you looking for an out-of-the-box health tracking solution like Withings, or do you prefer a local-only presence sensor built for Home Assistant to control your lights and routines?

Yes — there are a few good options, but the best choice depends heavily on what you mean by “home automation.”

My top picks

Withings Sleep Analyzer

$173.10

Eight Sleep Pod 4

$2,599.00

1. Withings Sleep — best all-around sleep tracker

• Thin sensor mat sits under the mattress; nothing to wear.
• Tracks sleep duration, sleep stages, heart rate, snoring, sleep score, and bed presence.
• Home Assistant has an official Withings integration, so you can use its data in automations.
• Works with spring, foam, latex and memory-foam mattresses, generally 4–15" thick.
• The catch: Home Assistant integration is cloud-based, rather than a local sensor connection.

2. SlumberTek — best if automation is the priority

This is particularly interesting if you're running Home Assistant. It's specifically designed as an under-mattress bed-presence sensor, with Home Assistant support and a local-first approach.

It is better for automations such as:

• “I'm in bed → turn off lights”
• “I'm out of bed → turn on hallway lights”
• “Someone is in bed → set HVAC to night mode”
• “Bed vacant in the morning → start coffee”
• Bed occupancy/presence monitoring

The downside is that it's not really a full sleep-health tracker like Withings; its strength is automation and presence.

What I'd buy

If you want sleep analytics + automation, I'd go Withings Sleep.

If you want Home Assistant to know whether you're actually in bed and use that as an automation trigger, I'd go SlumberTek.

If you tell me what home-automation platform you use (Home Assistant, Apple Home, SmartThings, Hubitat, Alexa, Google Home, etc.), I can narrow this down to the best 2–3 options and check local vs. cloud integration, API availability, and whether you can trigger automations from sleep/bed-presence events.
