The Belkin Conserve Socket timer does a good job in our household. We often forget our washing machine off, the device does a good remedy. The problem arises, however, when consecutively washed twice. Since it may be that the three hours of battery life are scarce. But so far it has worked. Background of the acquisition is that our washing machine which then abundantly available warm water uses in running thermal solar panels on the roof for washing, to save electricity for heating. If the machine after the end of washing, however, a longer period are turned on, so it consumes unnecessary power for the control system and the solenoid valves. But now we have created with the OA device inexpensive remedy. A star deduction there is that the device has only three selection stages. An extension to 1H distances up to max. 6 hours I found useful. The device would offer certainly still more buying potential.
