Hey guys,
I own a Poolex Silverstar FI 120 heat pump for my pool which was connected to the Tuya-cloud.
After several faults with not-working automations using the timer in the app - the heat pump didn’t turn on and off correctly - I decided to follow this guide to “convert” the cloud-system to local system controllable with ESPHome:
But it seems there are some issues, maybe because I used an ESP32 (from here: https://www.amazon.de/gp/product/B0CL9VZKMT) instead of the ESP8266 the creator used:
I tried it with another ESP32 before (ESP32-WROOM-32) also with no luck, even the actual temperature is now shown 
After flashing the YAML to the ESP32 I get this output in my log:
INFO OTA successful

Could you point me to where I obviously made a mistake?
