230V Relay Switches for Home Assistant?

I need to control 24 lights in my house, so I need a 24 channel relay switch (or 3x8-channel relay, or 16+8, or even a 32 channel relay). I don’t want to use rapsberry pi gpios, so my alternatives are ethernet, z-wave or WiFi. Can you recommend me anything?

Why not raspberry ? THe other solutions will cost you a lot more money. What load will you be using them with ?

Because I don’t want wires. I would like to be able to detach the raspberry easily, and if I have to disconnect and re-connect all gpios…

I’ve just found this one: HLK-SW16. What do you think about it?

The board is inside a cabinet I have for all the connections and devices. I can use wires, but I don’t want to disconnect and reconnect all of them if I need to replace the raspberry pi. But, maybe I can use some gpio extension board, or anything like that, so I can detach and attach all at once.

You would disconnect the board, not all the wires :slight_smile:

Yes, I think it is the way to go :slight_smile:

Add a header extension with all the wires you want connected, then if/when you want to move it just pull the plug

Nice! Thank you :slight_smile:

EDIT: I think this https://es.aliexpress.com/item/4001338318598.html with one of this https://es.aliexpress.com/item/4000015066223.html is the perfect solution

I used this something similar to control 16 lights:

Thank you. I finally bought 3 boards like this: https://es.aliexpress.com/item/32572982881.html
They work with 5V, and using solid state relays.

Yes they look good, but only switch 2A @ 250V so not suitable for me

They are enough for me. I’m using low watts led lights. If I’m not mistaken, it will support 250V*2A = 500W, 62,5W per channel.

Yes 2A@250V = 500W, that is per channel (each “relay” can switch 2A), although I’d probably not want to use the full 500W on each channel at the same time

500w per channel? Wow! That’s more than enough for me :slight_smile:

What did you modify on the setup I shared? :slight_smile:
