Help to chose the right hardware to control relays

[Serg!o]

Hi,

I have an existing home automation setup and need your advice please.
I have multiple modules of relays as on the picture below, they are DPDT relays, 12v coil.
32 relays in total that I control with a device I bought online 5 years ago (Arduino with 8x4 (32) outputs), it listens to MQTT brocker on Home Assistant and basically turns the relays ON/OFF, which are controlling all my lights and a few ceiling fans/exhausts.
This device becomes unreliable and freezes from time to time so I need a replacement.
Can you please recommend a Kincony device so I can manage my existing relays.
Thank you.

use KinCony E8v3 board.

I already have relays installed, don't need another relay, only need a device that can turn them on/off.

chose B8M mosfet controller.

I have 32 relays. Can T32M or T64M be used in my case?

[admin]

T32M is ok, if you want more channel of output, chose T64M.

Can you please also recommend the right power supply for T32M. My relays are 12V, 32 relays total, but I never turn them all on at the same time. Will it be enough to use 12v 3A power supply?
Thank you.

12V 3A is ok.
