New EMFIT HRV Monitor System

FTC: Affiliate Disclosure: All links pay commission

EMFIT QS has been upgraded to include new sensors that can be embedded into mattresses. This is a development from the previous system (reviewed below) that allowed the sensor to reside underneath the mattress – whilst still working ! I use one myself.

The new sensor is advertised to be sensitive enough to distinguish between the heart beats of two users in the bed.

If the new product is to be embedded into mattresses then it won’t be for consumers directly?


There will be a new update to the product I just don’t know when. Here is what I found in the press release.

For individuals

Emfit is launching its upgraded sensor technology to provide more stability when monitoring movement and breathing readings for one individual when two people share a bed. The flex-material sensor pad slides easily under the mattress for comfortable contact-free sleep. Emfit’s sensors have been used in numerous scientific studies. These sensors provide highly accurate readings for:
• Heart rate
• Heart rate variability
• Time in bed, bed exits and returns
• Sleep time
• Stages of sleep (deep, light, REM, total)
• And more

EMFIT QS upgrades include:
• Designed for smart home integration, monitoring room temperature and humidity
• Added Bluetooth for easier initial Wi-Fi setup and use during travel
• Autonomous – no app, software or phone required; no batteries to charge; data is stored in a secure cloud server
• Dashboard can be easily shared as desired, with comprehensive visual graphs.
• 10-hour minimum buffer memory expandable with micro SD card to store longer periods of data
• USB-C allows data output to other peripherals, also from cloud.


Ha. Clearly I’m looking to get one and want to get the newest version. Interesting thought on the alert based features. What alerts were you thinking about? I think I wish they had an iOS app. How do you like its functionality without iOS or Android integration?


Have you tried comparing the data EMFIT gives with something like ithlete or hrv4training? Not so much caring what the specific numbers are as they will be different (one based on data during sleep, the other done after waking up) but the ability to tell if you need to recover more or not. So the action to take based on the data, not the data itself.


More wondering if emfit gives just as good feedback which requires them both to agree on when you need more rest or ready for more load.

In order for them to give useful feedback it seems like they need a baseline and have you use the tool everyday. Emfit seems like its all automatic which is great while the smartphone tools require you to measure everyday. Does seem like being upright is slightly better position wise then laying down plus you can since you know when exactly its measuring you can be sure to hold a position that gives a good reading while with emfit, you’re hoping the reading it picks is valid. So if you’re willing to do the work a smartphone app should be better at that data point.

Me? I’m too lazy to always remember to use the app first thing in the morning so if emfit comes close to the smartphone app I’d rather use emfit or something like it.


Yes there is also a new updated sensor that will be included for manufacturers as you mentioned.


You know what could be useful? A list of all the sleep aid/trackers that are out there. (ignoring wearable trackers that are focused on other things like fitbit and garmin devices or things everyone does like white noise machines) with the basic metrics they try to track (HR, movement, breathing, etc) and/or how they try to help you sleep (sunrise/sunset simulators, audio cues (think, sleep shepherd), Somnox’s sleep robot, etc)

Does seem strange that the device that help you sleep don’t work together with tracking devices. So thinking I’ll need a Somnox sleep robot and EMFIT


The idea is less of a review, more a collection of all the devices out there as there are lots.

I used Beddit from the beginning. It was ok but annoying how you had to always start and stop it (plus the initial issue where the device needed more power their USB power supply gave which v2 fixed) The main improvement only came to Apple devices like auto sleep detect. Seems like a good device but ios only, not worth it for android.

There is Nokia Sleep now which looks like the Withings sensor (Aura) without the clock with sunrise/sunset simulator (They bought withings and killed the Aura right after the purchase). Doesn’t seem to measure as much detail:

There is the Eight sleep people who have a bed (like emfits’s new entry) and a mattress pad which is a heater and tracker of heart rate, breathing, etc but not HRV

Beautyrest has one, Zeeq pillow, Oura ring, hello sense, SevenHugs HugOne, Resmed, Thim ring, and I’m sure lots more


Assisting sleeping helps with everything. For monitoring will have to at least track heart rate. Some might be better by tracking HRV and providing a better athlete focused UI but seems like you can tell a good amount by just looking at the trend in resting heart rate.

Why they don’t do much of tieing that data with power meter data that tracks your status, I don’t know
