After my friend (@pjocke) had some issues with his heating and started monitoring the incoming hot water from the tenants association, I thought it would be nice to monitor the temperature in _all_ the rooms of my house…
I use Homey for my home automation, and was looking for something that would plug in to that. So after some researching I found out that Xiaomi Mi Smart Home Temperature / Humidity Sensor 2 works great with Homey, but it needs to be flashed with a custom firmware since they are (of course) supposed to only work with Xiaomis own “Mi Home”-app.
Well, said and done, I bought some sensors and started the process, found out the hard way that my Browser (Brave) needed to enable some experimental flags to use the Web Bluetooth API.
Since then there has been new firmware releases and it’s now also possible to flash the sensors with a firmware that enables Zigbee.
Just look at it…
And with Insights in Homey, I can generate nice graphs showing the sun factor on the room’s facing south..
Next step.. MORE SENSORS! (…and perhaps some cool automation based on the output of the sensors!)
