So I have been using various relays over 2 last years, mostly driven by Tinkerforge I/O modules but they sometimes prone to interference from the 230AC and sometimes do freeze or I/O module is registering bogus inputs. Especially when used next to the large loads like 2kW poll pump.
So I look for some other module that would have relays or better relays and some inputs for registering button presses.
Needs to be super reliable. With wired Ethernet and POE
