Ok then I can stay with 3V3. Anyhow I am still doing something wrong, device register with the server it works fine, however when I turn on relay or touch the button I don't get 3V3 on relay pins, to be honest nothing changes on relay pins. Is there any check I can do?

What does it show you on the serial monitor?
do you have A0 A1 A2 connected to GND? "red marks"

It seems that MCP23017 is not working.
have you tried disconnecting from the power supply for a few seconds to restart everything, maybe the MCP23017 is stuck?
Are you using the code from the first page of the thread?
are you compiling with arduino ide?

Yes, using arduino ide tried everything. I think its broke MCP23017, ordered new one and will check that. Thanks for help.
