Shelly Plus H&T Works only inside 0°C to40°C

In my second apartment, I would like to monitor the outside temperature to understand the impact on indoor temperature and set the additional heating on when it gets too cold and brings in the risk of freezing water pipes.

Is there a possibility to have a external temperature sensor (wired) to be plugged in to Shelly Plus H&T?

Or would there be another solution to use to monitor outside temperature? So that I can read it using Shelly remote app when I am not locally there in the building.

I'm using a Shelly BLU HT for external temperature.

I have an UNI with humidity/temperature and light sensors, that is connected to the boiler, allowing me to override the internal thermostat turning off heating when i forgot to program it, or turning on if I expect to come back earlier, of course beside these remote control you may also use its output for actions: in my case it send a command to close curtains when temperature go below 10 and is night, but in your case you may set that under a certain temperature forces on the boiler.

Thanks msschaeffler for the answer. My understanding is the BLU HT has only bluetooth radio, and it doesn't connect to wifi/WLAN, and thus doesn't fit to my purpose.

Thanks wooly. I haven’t paid attention to Shelly UNI before. I need to check further the possibilities to use the UNI. It sounds feasible at least with the analogue input it should be ok to connect to external temperature sensor. And it has WiFi/WLAN/BT radio. So in fact the BLU HT could be connected to it….though direct connection with a temperature sensor looks a bit more attractive (less battery worries)
