Just got mine installed that arrived late last week. The right side originally was not detecting all that well, but peeling it off the frame and place it down being sure not to pull it tight and instead just lay it flat solved it.
Had been using Withings bed sensors but got really tired of them disconnecting and needing me to open up my HA install to the Withings servers so this all in one local only solution is working fantastic so far.
Is there any way to get the good piece cheaply (especially in terms of shipping) in Germany / Europe?
Otherwise I would also be open to a collective order.
Currently, we are only shipping from the United States.
Is it possible to get a discount on a bulk order?
Then I would collect interested parties in Germany.
Tom, I might be interested if shipping from Germany to UK would be “sensible”.
Feel free to place bulk orders and distribute the units as you see fit. I’ve added a 10% bulk discount for orders over $690 (10x dual sensors).
Just make sure buyers understand that you’re not an authorized distributor, so warranty options may be more limited. Also, be sure to factor in import duties when pricing your orders.
I’d just like to say I’m a happy customer from Australia. These sensors were amazingly easy to install and configure. Lay in bed press button on phone to calibrate, get up calibrate, done. I’ve had more trouble mucking with light bulbs.
Wife now loves underbed and toilet lights for midnight call 
Well done guys. The software in the unit is worth the price of admission.
Just got mine - easy to set up! Excited to try it out and see how it works, my quick testing seemed to work pretty well! I got the mounting kit and stuck it on a tempurpedic foundation under a tempurpedic mattress.
Curious how well you think this would work with a tube (7 I think) waterbed. Would the constant weight of the water be a problem with the force sensors? Obviously, compared to the weight of the person or even the materials of the tubes/liner themselves, the weight of the water would be much more force applied. I don’t think the current solution would work, but I’m interested in following development of additional versions for different applications.
It will not work with a waterbed.
It’s not just the weight of the water which will be a problem in your case.
Water makes it next to impossible for any kind of radio signal to get through, so any solution you go for would mean that the controller would have to be located well away from the mattress.
you would look at some way of putting the sensor of the side this way you would avoid the problem of weight and use the displacement of water / pressure against the sides
As mentioned by everyone else, I think there’s a variety of challenges you would run into. It’s not in our current plans to attempt to support that setup.
These look great! One question, though: Will they work to detect someone in the middle of a king bed? I change between each side and the middle as a sort of wear-0levelling so I need to be able to detect presence there too. It’s just me, so not too worried about which ‘side’, but just overall presence.
If you’re lying in the very center of the bed—between the two sensors—the reported values may be lower than if you were directly over one of them. However, as long as your trigger threshold is set below the value detected when lying in the center, it should still work reliably.
We also provide a combined sensor that reports if either sensor detects pressure. This is the best option if you’re trying to detect whether anyone is in the bed, even if they’re not directly over one sensor.
Thanks for the quick response! I thought that was the case based on the docs, but wanted to be sure I was thinking correctly.
I vastly prefer HA to OpenHAB (for many reasons) but one thing I did bring with me from my time there was the design pattern / concept of “time of day”.[0]
Essentially you set up a text field (or better, a drop down) [1] with several progressive “time(s) of day”, for example (these are actually mine):
You set this value by various events, typically sun rise, set, midnight, etc. according to your needs (which can be tweaked).
Then, you base all your automations off of that value. For example, turning on lights at sundown (“Evening”) and off at “Bedtime”.
This decouples the “time of day” value change from the actions launched as a result, making the whole shebang much less complex and thus easier to maintain and reason about.
So, in the context of this thread, being able to reliably set “Bedtime” (with one or more accurate bed sensor(s)) is crucially important to many automations which depend on that, and in fact precisely the reason I am here.
[0] I seem to recall reading a thread about this by rlkoshak (Rich Koshak), probably this one, but it has been many years (and looks like it has been somewhat edited since the original).
[1] In HA I implemented this as an input_select.
@stephenp93 It’s probably a result of the corner of the house, mattress, walls, etc. but my sensor is having a tendency to have blips of “unavailable” (see below). I haven’t analyzed the length of time but many of them look to be within 10 seconds. Is there a timeout or a retry that you are aware of that could reduce this bouncing?
What does your “WiFi Signal Percent” show? Also checkout the “Uptime”. Is that resetting to 0 each time it disconnects, or is it continuing to count up?
Uptime is 290,633s - so definitely not resetting. I’ve been wondering if maybe my little charger may be a little flakey - it’s just an old usb phone charger that does 5v / 1000ma.
wifi is at 90%.
Here’s a history for a few days of the wifi % and the wifi DB. Granted - there are a few days where i would expect some brief blips, but not nearly as many that seem to be occurring.
