I’m also changing the default value for polling interval to 60 (minutes) now
Thanks a lot for your effort with this app 
I also have a major battery drainage issue. My lock has been stable at 9-10 months battery life, but is now only max 4-5 days (issue started 19-20 Nov according to insights). Before changing the last set of batteries I set the polling interval to 1440 and also updated the locks firmware, but that unfortunately did not help at all.
Any possibility for a roll-back to pre-November until this is resolved? I have been forced to remove the z-wave module now.
I reinstalled and got the maintenance button now aswell. I put 1440 minutes in the polling just to be sure batteries are not drained. They are expensive nowadays. Thanks for taking the project though. Much appreciated! Have a good weekend
I can also see that the draining continues. 
I am also seeing significant battery drain after last update.
ID-lock 150 on latest firmware
There’s a new update on the way (v2.2.0) where I have removed the polling completely. Instead I have added an action card that can be used in flows for updating the lock status. I’m using this in combination with the Heimdall app before activating the alarm to make sure the lock status is correct.

My lock seem to continue to drain battery fast. A new set drained in a week.
It has continued to drain in five steps the last two days.
That’s strange. Did you update to v2.2.0? There shouldn’t be any changes that could affect the battery now.
BTW: My battery actually increased by 5% yesterday as the temperature increased, so I’m quite certain that the reported battery percentage is affected by the outside temperature.
Updated a couple of days ago. Changed batteries right now as the lock died. Will report back again if issue persist.
Thanks!
