Resetting my Ring System/sensors

Hi,I somehow had removed my sensors off of the base station. I’ve been pulling my hair out trying to reconnect each and every sensor but still no luck. Also the base station doesn’t pick up my keypad or extender.I have done the following:Reboot and reset the Base stationRemove all the sensors and reconnectUnplugged the extender multiple timesTried to reset the keypad many times.Nothing seems to connect.This shouldn’t be rocket science? Right! Please can you advise. From poor bloke going bald due to frustration.CheersNick
