Suspended until further notice, reason being: ESPHome provides overwhelmingly more functionality for ESP8266 platform, and is easily integrated (see DZ to ESPHome Integration).
It's possible that it will be reanimated at some point, there a few things ESPHome cannot do with required by DZ level of finesse.
- The board: Adafruit Feather HUZZAH with ESP8266, reason being - it features 1S LiPo battery connector and charger. Given the fact that the devices being developed will be most likely remote and wireless, this is a serious advantage. YMMV.
- Temperature sensors: Maxim DS18B20. Cheap as dirt, digital, noise free, and reliable.
- You might want to explore the Home Climate Control project, for which these edge devices were intended in the first place.
- hcc-esp32 - basically,
hcc-esp8266++on ESP32 hardware. This project is on the long term roadmap and will not get axed anytime soon, it will provide functionality ESPHome doesn't.
