    This is the one I currently use and it works perfectly down to a lower temperature than the one you mention. I can control it remotely with a relay board in my observatory as well.

    i second this really is quiet and efficient mine looks the samer but with a different name i believe also has external pipe for drainage

  2. the one i got has a small heater in i believe https://www.amazon.co.uk/Kemo-Electronic-M152-Capteur-pluie-Beige-Copper/dp/B000NI2QJC/ref=sr_1_5?dchild=1&keywords=rain+sensor&qid=1610727447&sr=8-5 although i wish it was more sensitive it does work pretty good,i have mine hooked up to a raspberry pi in my obsy which is connected to another pi in my living room via my network and my son has put a couple of programs on each pi which warns me when its raining ,it also monitiors a contact on my obsy door
