Uhome LFP 2400 Voltage Falling Under No Load Conditions

Finally got around to getting some measurements of latent power consumption of the lux ACS 3600 in standby mode just after switching from discharge mode ...

My system with with 4 Uhome LPF 2400 is located in a cool garage, approximately 6 degrees Celsius at the moment.

Coming in around 33 watts, equating to 0.8 kWh per day or approximately 10% of my system capacity.

So apparently Aoboet are currently developing a new app for battery monitoring of the Uhome packs. The local agent has told me that the app (Android / iOS) is going through checks before being released / available for end users.

Let's see if I eventually get the account details for the new app to check the battery health. If not I'll be resetting and putting them online myself and trying to avoid any more fruitless dialogues!

That marries up with the losses I saw as well which are ridiculous especially in winter. You lose 10% of your free solar energy only to have it replaced from the grid ???? A bit self defeating right ? The current Uhome app (NOT to be confused with the Aoboet app) seems to work fine. You can get some very detailed info from it.

Sorry to dredge this thread up but did you have your batteries on the old Aoboet app before using them with the new UHome app? The new app will not recognise the serial numbers of my batteries, I just get a "device not exits" (sic) message when I try to create an account. 

The default WiFi on my batteries have USR prefixes rather than ESP so I'm wondering if they are an older hardware/firmware not compatible with the new app.

In which case have you tried asking Infinity Innovations via your installer to get whatever needs updating done so that you can use the newer Uhome App - theoretically the Uhome batteries are sold will free future firmware updates etc 

Either way Infinity Innovations should be capable of sorting whatever is needed to enable use of the updated app. 

Although my batteries have ESR prefixes they were originally listed on the older Aoboet app if you went in via one of Infinity's default logins, then when everyone was talking about the new Uhome app I gave it a whirl to do the registration process and was able to add them to the new app - if that hadn't worked I would have been definitely pestering via my original installer to get it sorted by Infinity for the new app as they are sold with upgrade capabilities....

By the way, originally on the old Aoboet app I was never able to personally register my batteries, they seemed to already have been registered but I'd never been given login details, hence why I ended up using the default Infinity login I'd found on this very forum.

My batteries weren't registered by my installer, I registered them myself in the old app, but I'll send my installer a message at some point and see what they can do 👍🏻

Sorry no, come to think it, when reset my batteries just appear broadcasting their own barcode number as the wifi id - no prefix just a long alphanumeric number

Feels like maybe a firmware update is required - that should be fun with the very flaky WiFi on these batteries in my experience

From what I've seen in one of Jake's Infinity videos, they have a device that does the firmware update, it looks like it's via a cable not the WiFi...

yes they do have a device, but it looks nothing like the video! I have been through updating firmware on my batteries.The T&C's for the batteries says Aoboet must be able to remotely monitor the health of the batteries. One of the stack of 4 was updated to the latest version of firmware (v1.2.1.6) for "older" batteries and its caused a lot of issues, to the point that today infinity have said they will provide a new battery so they can view my stack and see how it is performing. The software they sent me had a "bug" and Aoboet provided another update v1.2.1.8, however this software wouldnt be accepted by the now faulty battery.

My route into this was I raised an issue with infinity saying that the warranty would be invalidated if no wifi capability. If you are getting no joy with your installer, use support@infinityinnovations.co.uk (youll get an email back saying the email address is only for installers and if you are not an installer you wont get a reply). Phil (tech guy) at infinity has been good once I got them to do anything. My installer was Biggreenbeard, so I also copied them in on the first email (BGG are now business only).  This is what they send you. The update process is not intuitive, especially if you dont have great IT knowledge, you'll need to speak to them as info on what to do is next to nothing. 
I'll post this on lux ACS3600 as well.

That doesn't look shady at all 🙂 I'm fine with IT stuff but I'm not sure the risk of a dodgy firmware update is worth it just to be able to use the UHome app and get better battery stats visibility. 

I have a different installer to you, maybe I'll ask them sometime but I can't see them being keen about sending out a USB-CAN dongle when the batteries (mostly usually) work fine.

Ian you may have seen my post on the lux forum, all my batteries updated to latest firmware for my age of battery (first iteration, think there are 3). v1.2.2.6. infinity have said my age of battery wont connect to the new uhome app. The only way to see them in the new app would be to have a newer battery as the master, you can then connect the newer battery to the uhome app and be able to see the rest of the stack. I haven't got a clue what the "improvements" are between the firmware versions!

Thanks for the update 👍
