New EB3A detected , configured but all data are unavailable

[PaulLacatus]

Got a new EB3A along one from last year. The new one was discovered by Home Assistant, configured but all data are unavailable

[GammaPotato]

i had the same issue since couple days. After removing the EB3A it cant even find it anymore?

[jdwannam]

The issue is that Bluetti enabled encryption on the Bluetooth connection for security reasons. They were getting complaints that people could remotely turn off people's power stations. There is already an issue tracking this, but it's enabled on all new Bluetti firmwares. There does not seem to be a fix for connecting to encryption-enabled devices yet.

how did they turn that on, on my EB3A? i dont installed any update?

There is any possibility to implement the encryption in the EspHome Bluetooth proxy so the devices can be connected from other devices than that are running BLUETTI App? There is a possibility to share a device trough a QR code.

I'm trying to decipher the whole thing. I'll get in touch as soon as I have a solution, but it will take some time

I have checked on logs on BT proxy

This is a working device

This is the new one that look like connected but no data available. It looks like connected but other data structure. Might be an encryption issue here ?

[GammaPotato]

@PaulLacatus pls read the other commends. Im not from the integration but im trying to help. Bluetti enabeld the BT encryption. Im on it.

[PaulLacatus]

@GammaPotato I fully understand but I don't know many things about BT encryption and I was wondering that my issue is from encryption or changed data structure . An device using encryption will show connected status ?

[Patrick762]

The integration was not meant to deal with encryption, so this can happen. I also don't think it makes much sense to prevent this behaviour at the moment. The big problem currently is the encryption which is not following a clear standard (they could have just used the bt pin which would've been easy to implement)

[GammaPotato]

@PaulLacatus i have the same issue. The most ppl have that. And connect to it is still possible but data cant be read because encryption

[PaulLacatus]

@Patrick762 you consider that contacting the producer and generating a ticket that it is not working anymore with three partie control systems and integrations can help to make them considering to open access ? Normaly in monitoring direction there should not use any security limitation as encription or passwords. In control direction they might have a point for securing comunication.

[Patrick762]

They're going to enable an open api, but they said it will take some time before this happens

[Patrick762]

The point is, for monitoring the device you have to write to some registers

Contacting the support wont help.

like jdwannam sayed.
