Victron VenusOS driver for serial battery BMS - LLT/JBD / Daly Smart / ANT / JKBMS / Heltec

Would have been great if we could edit the heading of that thread to add all the new BMS that it now works with. Then it might be easier to find.
 
Yes. The JKBMS does have a sleep function. There is a spesific command for waking that you can send it to wake up. But if you send it any command it will fail, but it should wake up as well.
I do poll the JKBMS every 1 sec so that does keep it more awake.

That's not what I'm seeing though - if I don't send any RS485 data when the BMS is in normal operation it is fine, but if I send data e.g. every 10 seconds, the device will power off entirely after some time (need to power up again with 9V battery for example). This is all when connected to solar charger and inverter, so normal operation.
 
Hmm, that sound more serious. I have not seen that it stops like that, only that is miss a reply every now and then.
