Using KaKu/CoCo 433Mhz Light switches in Domoticz

The power for our garden lights is provided by a socket on the inside of our house. A timer installed by the previous owner turned the lights on and off at a specific time. Unfortunately the lights are powered by 12V and directly soldered on this timer which acts as an adapter as well, so Removing this timer wasn’t an option.

At the local hardware store there was a discount of 20% on everything so I bought my first 433Mhz switch which was compatible with Domoticz: the KlikAanKlikUit APA2-2300R. This bundle contains 1 two-channel remote and 2 power socket switches.

The brand KlikAanKlikUit is often abbreviated as KaKu. The international name is ClickOnClickOff or COCO.

The setup was straightforward. First, via the learning option in Domoticz, I created a switch. During the learning periode of this switch I pressed the on and off buttons on my KaKu remote. Domoticz instantly recognised the switches. I did the same for the second button on the remote.

Now the remote was paired, time for the sockets to pair as well. I just plugged one socket in the wall and pressed the remote again to pair. Now I could easily switch the wall sockets with both remote and Domoticz.

However there was one caveat. The timer outside turned the lights on and off as well, which interfeared with the Domoticz switch state. The exact time is specified by red and black pins which you have to insert at the time of your choice. My problem was solved by only inserting the red pin (which turns the power on). Once the power turned on I simply removed all pins so it would stay on forever.

With this problem solved I started using the timer function in Domoticz. Instead of exact defined hours, Domoticz also offers variable times like sunset and sunrise. I programmed the garden lights to turn on at sunset and off at 11PM. Since the sunset time changes during the year I never have to reprogram and fixed hours again 🙂
