  1. Doug Carhart.

    If I have an Electricity power cut will it wipe out the pre selected timings on my switch.

    • mydome (verified owner)

      Hi Doug,

      The light switch timer is battery operated device and therefore works independently to the mains power supply. If you experience a power cut the light switch timer will remain active and so will all your timetabled programmes. Your programmes will only be erased if the batteries are removed for more than one minute or if you decide to change them yourself.

      I hope this helps but if you have any other questions please feel free to contact us and we will be more than happy to help.

      Many thanks,
      Customer service team

    One of the best security devices I have ever bought very easy to install and very easy to set up and also a good price

    We have 2 outside lights a nice porch light and a garage flood light. It always seemed a waste to have them both on at the same time. So I have this setup so that the floodlight comes on at midnight for security when the other one goes off. It has been working a treat for a number of weeks now with no issues and took seconds to setup.

    This is a fantastic gadget which is very easy to use. It works on a normal light switch and turns the switch on and off according to preset times by means of a small wheel/cog powered by standard AA batteries. It allows you to time a main light to turn on and off when you are out avoiding the need to plug in a lamp. A much better idea, especially if you have pets that could knock a lamp over. You can easily override the timer by pushing an on/off switch on the unit. It is installed simply by slipping a plastic cradle over a light switch and the placing the timer unit in the cradle with the cog wheel lined up with the switch. The unit can stay in place continuously or be removed if desired. It does make a whirring noise turning the switch on and off but it is only a second or so of noise. There are 9 separate programme opportunities over 7 days allowing almost any combinations of timings on different days. There is also a random function which turns the light on in the night at random times for about 3 minutes each time. This is useful if you are away as it mimics someone getting up in the middle of the night for a comfort break. I would suggest not using this feature if you are at home otherwise the noise might disturb you. The unit can be adjusted to move 1, 2 or 3 cogs at the same time depending on how many rocker switches are on the light control.
