After looking at the thread about the 433 MHz pool solution i wanted to make one with WiFi instead with an Fibaro sensor.
Sonoff was a good option to make one myself using the following parts.
Sonoff DS18B20 Waterdichte Temperatuursensor
USB Serial adapter for flashing with Tasmota and powering the device
I’m not the smartest when it comes to flashing devices or soldering parts together but even for me it was very easy to make this happen. I will explain the steps i took later.
Because i am using the TH10 it would be possible to even connect a pool light or something to the device and control this through Homey.
I will update this with a few photo’s later this week.
