Which Kilovault battery was kilovault_bms_ble written for?

[stevegoldsmith]

Hi

Which kilovault battery did you write kilovault_bms_ble for? I have a pair of 3600-HLX-v3 in the RV which has a bluetooth accessible bms and it doesn't appear to be for these....

I know Kilovault has been through a few generations of this battery since I bought them, and have since gone bust. When I try and connect to either battery with your code I get "_[E][kilovault_bmsble:057]: [...] No control service found at device, not an KILOVAULT BMS." so I am assuming it is for one of the newer batteries?

Thanks much,

My invoice says KiloVault 3.6kWh 300 Ah 12V 3600 HLX+ UL. I got them last year.

Are you sure you have the correct MAC address?

My yaml: I believe if you uncomment the esp32_ble_tracker section it will show the mac and uuids. Would be helpful to see if they match.

Thanks so much for the quick reply. Yea, that makes a lot of sense now. The HLX+ is a newer battery and they appear to have done a lot of work on the communications as that battery has an rs485 interface so batteries can communicate with each other, as well as apparently a better ble interface which the HLX-not plus version lacks.

Very much appreciate the work you have put into it. Hopefully the + has enough in common with the - and we can use your work as a launching point to talk to the older batteries.

Thanks again, /steve
