Hi together,
I would like to create small automatization in my home installation. I enclosed my current network topology, where coloured lines are part which i want to automatized.
Of course i want to add some sensors in the future (PIR,tempeture,motion sensor and some christmay lights etc).
Red and yellow lines represent two way switches, purple one way switch.
I need help which hardware, relays to use. I saw some wifi relays like sonoff mi, shelly, basically wifi relays.
To be honest i don’t want to use in every socket wifi relay and don’t have idea if it can controlled from wifi 1 if relay will be connected to wifi 2, i prefer ethernet connection to relay module.
I saw some configuration with 2 way switches, but some of them have problems for example to show real state of light in HA.
I was looking for something like kincony ethernet module switch KC868 + SWITCH TERMINAL BOARD, but there will be some other cheapest solution i guess.
I have also raspberry pi 4 with some relays, but i have no idea if this could be somehow used just for controlling.
I saw solution with HA running on rp and controling relays, but no one where HA in on NAS and rp is just for controlling relays.
I don’t have so much expreriences with such a kind of installaction so I appreciate every solution/idea what can be used.
