Hi!
I am looking for a WIFI thermometer for swimming pools with app and compatible with Home Assistant but I have found very few products: only PoolSense, which in Amazon Italy is not available and I would not want to spend more than € 100, if possible. Are there any alternatives?
I have read that many use a Shelly 1 with added temperature probes, but I do not have the possibility to connect it via cable to a power outlet, and how would I make it safe for electricity?
Ultimately, prefer ready-made solutions instead of Arduino or other.
A thousand thanks!
Safe is without mains connection
