Wired connection to my lamps

[oak condor]

Hi,

I need to contrloll 40 lamps with Home Assistant. The connection should be wired to make it as stable as possible.
I've found Shelly Pro 4PM already, however it seves only 4 lamps per module and its quite expensive. Do you know any other modules I can use for such architecture?

do you want something off the shelf or happy with a little work?

you could get a esp32 relay board and configure it with ESPHome and put it into a box of some sort.
there are a few options available but realistically the max i have seen is 16 relays on a board. which you could use 3 of and have some spares.

or you could build your own big boy using basic relay boards and gpio expanders powered by an esp32

@twilit coral thank you for suggestion, however I would like something which will required less manual work. Something from a shelf as you suggests.

athom make an 8 channel relay module that should be fairly out the box - https://www.athom.tech/blank-1/8ch-inching-self-lock-relay-for-esphome

you can find some 16 channel ones on aliexpress but they are going to hit and miss and might require some tinkering to get working.

you are probably going to struggle to find something "off the shelf" with more that 8 relays.

you could look at something like a rack style switchable PDU that's compatible with HA. but that's going to be an expensive way of doing it.

thank you Michael, thank you for this hint. I will resarch 8CH ESP32 RF433, the minus of it is that it doesn't have enternet connection

[twilit coral]

you could maybe mod it to include one but then your getting into custom stuff again

I'm running HA on PC - do I need any other modules to connect everythong together? sorry for this question, however I'm just noobie

esp32/esphome devices are just wifi once its connected to network the esphome integration will pick it up. sure they put a rf433 thing on that one too but you can just not use that

or did you mean for purposes of modding it to ethernet?

the athom stuff is pretty simple. you power it up. it will broadcast a wifi ap. you connect and access the web ui and input your wifi creds. then it will connect to your network and your in business
