SmartSense Multi - New batteries at 1%

I installed the SmartSense Multi with the batteries that came with it on my garage door. Worked absolutely perfectly for 5 months.

Yesterday I received a warning that the battery was at 1% so i replaced the batteries. Got another warning today then I noticed that one of the batteries was faulty so I replaced it with 2 brand new batters (fully tested)

20 minutes ago I received a 13% warning. 2 minutes ago I received a warning saying the batteries are at 1%

is this possible?

If accurate, that’s where your energy is going. Hardware issue, perhaps?

Your RSSI is very low, you may have shortened battery life due to the low signal strength.

BTK - Where i live is a tropical country and that’s likely the result of direct sunlight.
Now that it’s 9:51M here, the temperature is back down to 35.

Sidjohn1 - It’s at -79 now. But is this enough to eat through a set of batteries in a day?

Note, I do not have any repeaters and the sensor is through 2 think concrete walls and beside my reinforced garage door.

But still, the first set of batteries that I received with the sensor lasted 6 months.

Are these the new multi sensors or the gen 1 multi sensors?

These are sleepy devices, so they shouldn’t be constantly updating. Range can effect battery life, but not by that much. I am leaning toward hardware failure, something is draining those batteries abnormally fast. Mine list 9-18 months.

I have the same problem. Apparently, battery sensing has been an issue with the MultiSensor 6. Aeotec has a firmware fix (https://aeotec.freshdesk.com/support/solutions/articles/6000036562-how-do-i-upgrade-the-firmware-for-multisensor-6- ) which was supposed to address battery reporting issues, but it didn’t work for me. Hoping to eventually see a new firmware update. In the meantime, I’ve ignored the low battery warning and the sensors keep working). Not a good solution, obviously.

pstuart - I’m not sure which version as I can’t see in the API screen. However, my amazon order says
SmartSense Multi - http://www.amazon.com/gp/product/B00GM7V8K6?psc=1&redirect=true&ref_=oh_aui_search_detailpage

I purchase it on May 8, 2015 and it was installed around August to today, Dec 14th and running perfectly.

Given that I just tested 2 batteries before putting them in and it still shows 1%, I guess i’m just going to let it run out. Don’t really have a choice as I live abroad and can’t sent it back without spending more on the shipping than the item itself.

Those appear to be gen 1. Good news, bad news. Good news is they do work well and the batteries should last a year or two. Bad news is the batteries that came with them were probably old.

Anyway, since they are sleepy zigbee devices, the battery reporting can be a little slow to update. Even though it is sent with every heartbeat, ST doesn’t always parse it, which is beyond me.

Give it a few days and see if it updates.

Also, if you have a battery tester or multimeter, just check the voltage on the battery as a percentage of capacity, that will be the true battery stats :smile:

In a day? I think its highly unlikely. The difference would be closer to getting 6 mo instead of 1 yr out of a set of batteries. When i worked with ST support they told me anything below -75 is low enough to cause issues. -40 to -60 is the sweet spot for most devices.

Thanks for help pstuart and sidjohn1.

I’m not at home right now but the api is still showing 1%. I tested them before putting them into the sensor so we’ll see if it updates in a few days.

Will let you know if it does indeed update. Been a day with the new batteries already though.

I’m wondering if maybe it got wet or a little creature got inside and shorted something although it seems to still work and I didn’t notice anything inside.

Just put two batteries in this morning. Instantly the sensor showed the battery at 75%. Approximately 5 hours later, I get a warning that battery is at 13% and then a few minutes later I get a 1% battery warning.

Here is from the API
