I’m planning to build several WiFi connected devices for home automation: an AC remote control and air quality sensors. These devices would send data and be controlled through a local server. I’m considering two approaches: running custom software on a server PC (hardware to be determined) or integrating with Home Assistant’s protocols and purchasing their hardware. Would using Home Assistant be excessive for this use case?
It’s been a while since I messed with home automation, but ESPHome was amazing to program ESP microcontrollers (i.e. you most likely wouldn’t have to write any code). You can use ESPHome devices with both Home Assistant and Openhab (using MQTT, IIRC). The last I checked, it was easier to program your own functionality in OpenHAB than Home Assistant.
