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?
HA is definitely the largest adopted. OpenHab is probably more geared for developers, but has a more concise and powerful automation system.
As for hardware to run it on: get a cheap n100 Minipc and be done with it. Uses 6-12W, and it’s going to miles.kore efficient for this use than a regular PC.
