I’ve had an Iris v2 sensor on my patio door for close to a year on the original battery. I got a low battery notification a few weeks ago (can’t complain about a year, although several other Iris sensors that I installed around the same time are still showing 78%), so I swapped the battery with a fresh one.
I apparently managed to put the sensor into demo mode (forgot about having the contact open when replacing the battery) and noticed a few days later that I was getting the multicolored blinking light and that the battery was already down to 11%. Replaced it again with a brand new battery with the contact open, no blinking light and no demo mode. But…here I am a week or so later and that new battery is already down to 11%. It’s actually been as low as 1%, then bounced back to 11%, then 22%, then back to 11%.
Any ideas what’s going on? Is there anything I can do about this, or do I have a failing sensor?
