Hi all, hope you all are doing well.

I am new to Homey and I am currently looking into how to read values from out room thermostats.

> **[Room RF thermostat BT-D02-RF](https://wattswater.eu/catalog/regulation-and-control/watts-vision-smart-home/thermostat-bt-d02-rf/)**
>
> Electronic thermostat with radio frequency back-lit LCD display (868 MHz) designed to control different types of heating and cooling\*\* systems. Temperature control

(Radio frequency 868 MHz, \<10mW.)

They are not very smart. My current hardware does not support “smart-options”.

I am looking for a way to read the signals RFID (836mhz maybe) from the thermostats to the central unit.  
A very nice to have is to read the battery level, is possible. With multiple thermostats and bad display - it would be very “smart” to be able to read the battery level from these thermostats and thereby receive notification/flow with this information.  
OR just read the current temperature from the thermostat.

Is it possible with homey to sniff on this protocol/RFID/868 MHz from my Homey Pro?

This feature is one of my best wishes for christmas…

Best regards  
The home service-guy

Sorry, 868MHz is not possible @ Homey, except for the zwave protocol

Thank you for your response.

I had hoped for some generic device or something - that would have been awesome.  
Or I had hoped for some small device as an add-on to support this. Dammit.

Also, maybe the thermostats dont report low battery in the communication.

YW, Kim.  
There is a way, but not tested by me.

The previous Homey models should support 868MHz, but I don’t know what it does and doesn’t do in real life situations

Used Pro 201x models are sold starting around €75 - € 100  
With the [app set Homesh](https://community.homey.app/t/app-pro-homesh-controller-homesh-satellite-connect-homey-pro-2023-to-homey-pro-for-led-speaker-zwave-satellite-and-network-resource/70369) (controller & satellite), you can use the 868MHz devices with a Pro 2023

It’s the same as 433Mhz support, in that you need an app for device support.
