I purchased two W20s, both of them are faulty. Therefore, I would like to know if there exists an alarm-system from another vendor that can work with the Kerui-Sensors (which seem to be OK). I have a lot of Kerui-Sensors and need a reliable base station (with GSM).
Please tell me, which systems you know that really work.
