Fibaro Window/Door Sensor battery dying every few weeks

[DinoKustas 1]

I'll grab a magnifying glass and have a look today.

 

When included it continues to flash as if to suggest inclusion error, but continues to send breach and safe messages when magnet is moved. Then it goes offline after about 2 hours, waking up when magnet moved, but again going offline lol. Not ideal when you want to arm/disarm in a group.

Scrap that actually, it has stopped responding altogether again. Bah.

I'm sorry to hear it's such a struggle. I'm a bit frustrated too, with myself, because I surely had this kind of trouble at least once over all those years. But I keep thinking the same things: not a good battery (high internal resistance), reset and/or exclude and include, replace battery with door open, not closed, check glass tube, check (both) tamper switches. The only thing that keeps popping up is this: I *think* I had this issue and that I replaced the D/W sensor, thinking it was a hardware issue. The one that I took off, ended up on my desk and I recycled it as a remote control (added a switch, put it in an enclosure) - several days or weeks later. Both sensors still work! I'm sorry, I really can't think of anything special. It's as if removing it, resetting it and reusing it solved the problem.

Maybe one little thing to know... *if* the radio of the sensor would be stuck "on", that would cause high power usage. A fresh battery would drain in roughly (1200 mAh / 40 mA ballpark) = 30 hours. That's not very long. Take that with a very big margin. If, however, you think this battery was empty after only a few hours, then drain would be much higher, or it wasn't a very good battery. Do you have a temp sensor connected to this module?

You may be on to something. Newly installed battery 2 days ago, completely flat now according to my multi-meter. 

 

Brand new battery that I've installed into others. I'll give it a new battery and if still the same then it will need to be returned!

Well, I have same problem with three of door/window sensors version 2.5. One was loosing association with HC2 in group 2 usually after rebooting HC2. When that happened it was marked as dead and also during wake up transfer was always failed. I excluded it, reset and included two times and now after second inclusion seems to be OK.

 

Other two v2.5 same problem as you have. Working for sometime and then they appear dead. Batteries found depleted. Even I installed new batteries I had to exclude them by force delete. Then I reset both of them twice just to be sure its done properly. Included both of them again and installed them on place. Then I did mesh network reconfiguration for near by dimmer module, smart plug and both of them by waking them up. It is now more than three weeks and they still working ok.

 

I also had problem with new z-wave 5 door/window sensor version 3.2. After only few days from inclusion it reported battery empty. I checked battery and was of course good. Exclusion, reseting and inclusion helped and now is ok for over three weeks.

 

Oh, and just to mention that this door/window sensor do not have anything connected.

Thanks for your input.

 

I've now reset this one particular sensor a number of times so I think there is definitely something wrong with it.

 

I'm still keeping an eye on the front door sensor though to see how that continues to function, so far so good.
