I am using SmartThings Mobile App version 2.6.0 (1412) and have the Zen Thermostat. On my Zen Thermostat I am getting a “Battery Error” with an indicator that the battery showing depleted on the SmartThings App (but not on the Zen Thermostat itself. This is with a fresh set of batteries and, other than this indication, the thermostat functions normally.
Has anyone else seen this error and resolved it?
I’m seeing it myself, but have not resolved it.
I bought the Zen because I didn’t think I could supply power, but I found the C wire tucked away in the wall. I’m half-tempted to just dig that out and re-configure it to be wired.
I’m using Amazon Basics rechargeable AA. I have not tried standard disposable batteries.
I am seeing the same error. The batteries in my SmartThings base had indeed failed so I replaced them. Did the same with my Zen. Error remains the same. Rebooted the app and rebooted the base. No effect. Have not figured a way to unlatch the error message.
same here, replaced new Duracell battery, error still there
Not that this helps you all, but I’m seeing the same error. I replaced the batteries in the Zen thermostat (which wasn’t itself reporting low batteries) and still I have the error.
I’m going to try deleting the device from Smartthings and re-adding it tonite to see if that resolves it. Would appreciate if anyone above has resolved the error that you post here!
Has anyone found a way to get around this? I can no longer control the thermostat via smartthings with this error?
I opened a case with support and I can now see the battery percentage.
FWIW, I still see the battery error 100% of the time, but I am not able to control the Zen thermostat. So, everything is “working” but the battery error still exists. I just ignore it, now.
Everything was working fine until I replaced my batteries a few weeks ago, then the battery error came back. I opened another case with Smartthings, they responded and checked a number of things and have now referred my case to Tier 3 support. Even with the battery error condition I can control the thermostat, I just have the Battery Error indicator.
Today - for the heck of it - I replaced my batteries with Rayovac rechargeable that I have and the battery percentage error went away. Duracell and Amazon Basic batteries were the other two that I tried, and those two brands did not work.
I am also considering having my furnace people wire up the C-wire the next time they come out for my scheduled maintenance.
Whoops, I meant to say while I still see the error I can NOW control the thermostat.
That’s really interesting that a different brand or type of battery would make a difference. No way this should be that sensitive!
Thanks for the update. I’d appreciate you posting again if you get anything interesting back from ST on the support case.
Dean - I will update this thread once I hear back from Tier 3 at Smartthings.
This thing was eating batteries left and right for me, so I dropped it from ST for now, waiting on you guys to get a resolution before I re-add it.
I’m using rechargeable AA (Eneloop and Amazon Basics), but it was going through a set of batteries every 3 days.
Since removing it from ST just after Thanksgiving, I haven’t had to replace them.
A new device handler has been posted only a few hours ago here: https://github.com/SmartThingsCommunity/SmartThingsPublic/pull/2671
It changes the algorithm used to measure the battery remaining percent and it worked for me. I now have a 100% instead of a battery error.
I used these instructions to install the new device handler: FAQ: An Overview of Using Custom Code in SmartThings
You can change it in the IDE without having to remove the device.
YES!!! Thank you @routerhelp1
This worked for me. I’m back to 100% battery. I really appreciate you taking the time to post the fix and the instructions.
Happy New Year!
Awesome! I will be re-adding this to ST this weekend. Desperately needed with the negative temps.
Thank you for creating and sharing this device handler. I finally got around to applying this to my Zen Thermostat and it worked for me as well. I’m a newb when it comes to device handlers, and the instructions were very clear. Much appreciated routerhelp1.
What did support do it correct it? I have the same issue, and with winter coming up, want to ensure the Zen functions as it needs to!
I am not sure what the tech support people did, but I do know that the changes were made by SmartThings developers and not by Zen. My battery percentage is still working.
While I was waiting for SmartThings to complete their changes I did apply the device handler (customer code) as described by router1help… and that worked. I backed out the device handler/custom code once SmartThings fixed things.
Thanks. I’m going to test the DH today to see if it resolves my issue. Zen’s tech support suggested I remove and re-add the thermostat, but hoping not to do that.
