Flume2 not reporting, Battery already dead?

What's the Flume2 sensor battery life others have got? I've had mine for almost a year now running solid and now the sensor isn't reporting anymore. I checked water meter box, its still there, not stolen.. :joy:

From the online portal:

Been dead for a couple days. I have no notifications of low battery on app or web portal..

Bridge is online, so that seems to indicate batteries died. Does the unit still look like it's solidly closed, hasn't been disturbed?

I've only had mine for a few months so not too familiar w/Flume battery issues.

@tomw @erktrek @cgmckeever - any comments?

My batteries died after a little under a year. I ordered another pack (about $20), but when I actually opened up the sensor enclosure I noticed the existing pack just had 4x AA batteries that I could swap out. So, I would first check to see which original pack configuration you have.

Low battery alerts need to be enabled in your Flume account (Settings -> Notifications -> Low Battery Alerts).

My first set of batteries lasted 9 months. I received emails warning of low battery. When I changed batteries, I added a second pack to the sensor. Hopefully this will get me 18 months or so next time. :slight_smile:

Yeah, they sure wised up to that money-grab (replacing a simple user-swappable AA pack with a proprietary sealed pack at 20 bones a pop) pretty quickly lol!

Well, they gotta keep a revenue stream going one way or another, I suppose.

I'm lucky that I got one of the basic packs with mine, so I was able to easily power it with a battery conversion kit. Beyond old vs new battery pack, I realize the placement of many folks' meters do not permit that luxury.

Are these 4 AA batterys Alkaline or Lithium? Will think of a work around to replace with off the shelf AA's.

Here's a post from another thread showing the 2 battery packs (old plain black and new sealed grey). The new grey pack is lithium for sure - I got one to check out earlier this year, and it's labeled as lithium. If you have the old black pack, I'd recommend putting lithiums in it for max life.

Although mine originally came with the old black pack, I don't recall what type of batteries it shipped with. Lithium is rarely the wrong choice over alkaline though.

LOL, I started that thread which resulted in me getting the Flume. OK, will get into it in a few days and see what it takes to get off the shelf Lithium AA's. A gopher has kindly covered in it in dirt so will need to clean out the ground service box.

Good stuff - that obviously whooshed over my head! Hopefully, you have the old pack and can pop in some lithium AAs without much hassle. Otherwise, I wonder if anyone sells a 4-AA battery pack/harness (like the old black one) somewhere on Amazon -- I should check that out one of these days...

@scunny was able to open the gray pack with a T6 torx, but it sounded like it would be a hassle messing with its internal battery setup due to things being soldered in place.

Update: So its been intermittent on/off but now 100% dead. I took the battery pack out, cut off the shrink wrap around it and replaced the 4 AA battery's. I used alkaline because I dont have Li batterys on hand, will get some for next time around. If you do this make sure you mark which side is up on the pack case because that will get lost with the shrink wrap cut off. The batteries hold tight. All good, no need to buy the flume pack.

If you have the newer sealed pack I dont see why one of those RC car servo 4 AA battery holder packs couldn't be modified to work. Seems like the same size. Just need to make 2x in series then parallel to get ~3.2V out.


any one else do the conversion on the newer sealed pack? Just got the low battery alery.
