  • Control CoTech Remote Switch With Arduino (433Mhz)

    I have some 433MHz units like these and you also have to pair them to the remote in a similar way, but if power is lost, so is the pairing and you have to set them up again - which is not ideal for an IoT setup where you want confidence that the units are still remotely accessible after a power cut. Can anyone tell me whether the CoTech units remember their pairing if power is removed (permanently or for a period of time?). Plan B is to use some other units that have rotary switches to set them up so you always know how they are configured.Thanks
