I’ve never seen this issue. Did you build you own OpenGarage or did you buy from us? If you are using a relay board, note that many relay boards are ‘active low’ type, and that could explain the reverse logic. If you are using your own relay, and use a MOSFET to drive it, make sure you have a resistor between gate and source to keep the MOSFET off during startup.
