I have a previous version of the Aeotec door/window sensor. It is the Gen 5 model. I skipped on Aeotec in my motion sensor roundup thread because a number of users reported less then excellent results from the Aeotec Multisensor 6 and also the previous gen as well… and they are not cheap. I none the less, wanted to try a product from Aeotec and needed a door sensor and purchased the above named model. I am pleased with how it works and it is down at the bottom of a stairwell where other door sensors had occasionally dropped off the network. It was also only $30
It seems to me battery life is good with door/window sensors because they only need to transmit when the door opens where as motion sensors fire much more often. Powered by two AAA batteries it is at least 6 or 8 months old running the batteries that came in it and still reporting 92% battery level.
Literature for my sensor claims one year battery life average. This new sensor claims 3 years powered by the same two AAA batteries. some impressive optimization must have be done.
