I’m currently putting together a project with my pool and solar heating.
The pump will start with a set temperature differential and I have a RPI + DS18B20 ready to go.
What I cannot find is some plug and play outdoor wifi smart plug without investing in larger systems with hubs etc.
Not sure of your location, therefore power configuration. That said, I picked up some of these on ebay and flashed them with Tasmota and EspHome with good success for USA power. I like that they have a light sensor that you can access, as well as two independent controllable sockets. Bluetooth BLE to boot…
