I'm hoping someone has the make/model number of the door sensor pictured below. I'm trying to find a manual online for it so I can see what type of batteries it takes and get them ordered before I pop the pin out of the hinge and pull it apart..
If you get it to work reliably, id be surprised. I had several and ended up tossing them in the smart home drawer of despair. I ended up using contact sensors.
I won't disagree with you entirely. I've had two, and one has been tossed. This one has worked actually quite reliably for me for about 5 years or so now. It does seem to be a bit of an outsider.
I would use a contact sensor, but the door that it is on doesn't really fit one well. High moldings around the door don't really allow an easy fit for a contact sensor.
One thing I will give it though is that the battery does seem to last a lot longer than others I have used.
I have extracted neodymium magnets from laptop mechanical hard drives. The magnets are very thin and very powerful, allowing for a large gap between magnet & sensor. I paint the magnet and you can't even see it
Zooz makes an in the door one that works quite well. Also the xfinity XHS2-UE's work well with varied moldings because the magnet has spacers. Another one that comes to mind that works well is NYCE's zigbee hinge...
Sorry. I looked in the closet containing all the smart devices not in use, and good god if I ever did an inventory....and the Mrs saw it....shudder...not worth thinking about.
Unfortunately, it appears that the hinge sensors departed the closet to the unknown. Its possible one remains in a box in the garage, but thats probably a forlorn hope.
