Dead battery on contact sensor now having issues reconnecting #98

Open gullygossner opened 4 years ago

gullygossner commented 4 years ago

A battery in one of my contact sensors died. I replaced the battery but was not getting a connection to home assistant. I did a wyzesense.remove for the contact sensor and then tried reading the sensor with wyzesense.scan. The sensor is discovered but there is no MAC address attributed to the sensor (binary_sensor.wyzsense) and the MAC address for the sensor is something like /0/0/0/0/0/0/0.

Is there a way to get the sensor correctly discovered again?

Wyze sense 0.0.7 Home Assistant 0.104.3

Do you have another battery you can try? I've seen this issue as well and swapping in a different battery has resolved it for me.

I do have others I can give a try. Have you checked the voltage of the ones that worked vs the ones that haven’t?

I have, The one that was failing for me was showing at 2.9v vs 3.1v for a new battery, though prior to it failing it was showing 75% battery. I've had a couple go into this state while I have a couple that have no issues at all still on their stock batteries.

Unfortunately I don’t think the battery is my problem. 4.6V is my reading across a couple batteries and same issue.

Same thing happened to me. I suspect that the sensors are defective. The 3 (out of 18 or so) that failed this way ran their batteries flat in a relatively short period of time. That combined with the "no MAC behavior" seems to indicate a hardware issue. I also obtained another bridge and these faulty sensors did the same thing when I used that bridge. These sensors are very cheap and I can't help but wonder if quality was sacrificed along the way.

I was wondering that as well, this sensor is the same location (unheated garage) where another sensor experienced a similar fate (dead battery and then no mac address after replacement). I have a motion sensor in the same location and it has been tip top. The most unfortunate part is that in Canada I cannot obtain the sensors outside of the full wyze sense package.

Overall, the sensors (as a system), not very reliable for me. I have to bounce my HA server once or twice a day to keep them working. (They just stop "sensing").

Probably time to look for something else. (Looking into some of the new, small form factor, 433Mhz PIR sensors with a Sonoff RF Bridge and Espurna firmware for a cost effective alternative).

I have had the same issue. I noticed my contact sensors all lost their connection and were flashing either 3 or 5 times. I went around and reset all of the sensors and they all joined up but two of them. They were in difficult locations, so I didn't mess with them much, but when I tried to add them I got a message that the sensor was added as "binarysensor.wyzesense" with no mac address.

One of them showed up in the States UI (I'm gonna miss States for testing and troubleshooting!) and I was able to edit it and customize the sensor and put the MAC address back on it. It's working great now (with a new battery.) This final one will not show up anywhere with the MAC address attached. It will scan and attach, but no MAC address so I can't get it to show up in entities or any where else.

Here's the actual message when it scans it:

Sensor found and added as: binarysensor.wyzesense (unless you have customized the entitiy id prior). To add more sensors, call wyzesense.scan again. More Info: type=1, version=16

I'm not sure where to go from here, but I'll post here if I figure it out.

Was there ever a solution to this? I tried all sort of things, but could not get a mac address other than a bunch of zeros after replacing batteries.

npotgieter commented 4 years ago

Not that I am aware of.

I never could get the system to work reliably for any length of time.

Found a different solution.

@gullygossner @adtinnis I had the exact same issue with a contact sensor that was not being used, suddenly ate the battery. After replacing with a new battery, scanning for the sensor again, it shows up with 00000000 MAC (or also seen in the configs as \0\0\0\0\0\0\0\0) I documents a work around to customize the entity from within the GUI, to put the MAC back in, and continue using this sensor for now here: https://github.com/kevinvincent/ha-wyzesense/issues/130#issuecomment-624960162

Time will tell if the sensor will eat the battery quickly again. More details in my other post. Cheers
