Help to chose the right hardware to control relays - Serg!o - 02-09-2026 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.

RE: Help to chose the right hardware to control relays - Serg!o - 02-09-2026 I already have relays installed, don't need another relay, only need a device that can turn them on/off. RE: Help to chose the right hardware to control relays - admin - 02-09-2026 chose B8M mosfet controller. RE: Help to chose the right hardware to control relays - Serg!o - 02-09-2026 I have 32 relays. Can T32M or T64M be used in my case? RE: Help to chose the right hardware to control relays - admin - 02-09-2026 T32M is ok, if you want more channel of output, chose T64M. RE: Help to chose the right hardware to control relays - Serg!o - 02-10-2026 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. RE: Help to chose the right hardware to control relays - admin - 02-10-2026 12V 3A is ok.
