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?
I’ll also vote to reconsider WiFi. Home Assistant supports a variety of local mesh networks that by default can’t connect to the cloud and whose devices are cheaper and lower power.
I use all three of zwave, Zigbee, and thread; ha works with whatever you need.
