I purchased the entire Yale Full Control Kit. Very pleased with the quality and reliability. Other then a wire free solution, the batteries are said to last up to 2 years AND the integration option with Hue Lights (flash at arm and when alarm is triggered) as well as options to connect to Alexa it's a great package that you don't need to be a electrical wizard to install. Nice to get some quality German product. Trust this much more than a cheaper "asian" model.

Well done Yale .....worth the money. Also - post sales support is excellent.

Instructions were not supplied - the instructions for the Yale Intruder Alarm kit previously purchased elsewhere had to be used. It wasn't easy to follow them but eventually I got it right.

Once installed, the tamper alarm activated every time the keypad was operated. A plastic pillar on the top depresses a tiny switch on the circuit board. The pillar was slightly too short. I glued a piece of card to the top of the pillar and it then worked OK. Once installed like that it works fine. It automatically picks up the code from the main alarm control unit. Entering the code manually would be much simpler and no less secure.
