I have installed on my camper rut850, and I try to use ignition pin for activate sleep mode for my router (i use two way switches - one in cab an another in living area).
But it does't work. I check voltage on wires and it seems ok. On power wires is always 24-28V (depend on on/off engine), on ignition wire then switches is off - 0V and 24-28V then is on (depend on solar panels).
What i did wrong?
