After buying several Aqara W100s, I realized the buttons weren’t supported by existing apps, so I wrote my own.
What works:
Temperature, Humidity, Battery
Buttons: Up, Middle, Down (supports single, double, hold, and release)
Try the test version here:
I though I would share as others might have the same problems.
Hello
I own a few aqara w100 and they are recognized with their buttons when included as matter devices
Are these reliable? I am considering switching my Zwave battery operated Thermostats as these are eating battery.
Do you have an Aqara hub?
My W100 buttons did not work with matter but the temperate did work. I dont have an Hub.
I don’t have a hub, my 3 W100 work flawlessly and I have programmed all their buttons without problem
Hello,
Can w100 be used as a climate controller, as it is its primary purpose? I have homey pro, but I cant seem to find this device in Homey Aqara app.
Tried the test version but fail to install W100. It looks for Zigbee connection but does not pick up de zigbee/thread divice. Installing it as matter device works, but only as a sensor.
Installing as a matter device works and the W100 can be used as a temp and humid sensor. Also the the buttons can be used. What is missing is the capability to set a target temperature with the buttons and to show that on the display. The “Relax Aqara” app probably does not solve this and has no added value. (I hope I’m wrong here)
Thanks for making the app.
I have a Philips outdoor sensor that gives me the temperature outside and I get it into Homey and, among other things, displayed on my mobile phone via HomeKit. I bought a w100 with the desire to display the outdoor temperature on the screen for the secondary sensor. I don’t have an Aquara hub. Is it possible to program this function in?
Thanks in advance for your help.
Hey everyone,
I had almost given up on this project… I couldn’t figure out how to get the thermostat mode working so the temperature could be controlled directly from the device buttons. But I decided to give it one last shot, and I’m really glad I did!
The test version now includes thermostat mode, letting you control the desired temperature from the device itself.
Test version: https://homey.app/a/se.arserius.homey.aqara/test/ (The description includes a full setup guide.)
Quick setup — steps 1, 2 & 4:
Pair the device with Homey.
Create a flow with a THEN action to set the thermostat mode on the device (only needs to be done once per device).
Create flows using the WHEN trigger for when the device changes the target temperature.
After update W100 is working pretty nice, thank you for your work!
One question, W100 is supporting to turn AC On or Off by pushing middle-button three seconds (LCD will indicate “ - - “)… Would it be possible to add same feature in the flow-cards?
And how about showing 2nd sensor temperature and humidity values at the bottom part of LCD, is this feature coming in the future versions..? 
Edit: Turning device Off is already implemented, my mistake… It’s Off state in thermostat mode.
I’m following this with great interest. Thanks for the app!
