Champion Generator Remote. Controls a Champion generator with wireless start. Replicates the on/off that the stock keyfob sends. You will have to pair this device with your generator just like you would pair a new keyfob.
I use this device in my travel trailer to allow me to run air conditioning overnight as needed without running the generator all night, and without having to wake up to turn the generator on/off. This device reads the temperature inside the camper, and when the temperature goes above the set point it will send an "on" signal to the generator. The generator starts, and if your camper thermostat is set to super cold then the air conditioner will start after the generator is started. When the temperature gets cold enough this device will send an "off" signal to the generator. The end result is you can sleep with air conditioning coming on and off as needed, and without running your generator out of gas overnight.
