Hello
I connected a battery with Pace BMS to a CerboGX via CAN Bus.
Its working, i get data from the BMS displayed in the Cerbo.
Now i tried to read those through Modbus in ioBroker like other Sources (MP2, Gridmeter), but i get the following error:
Error processing function Code 4, Unit id 225, start adress 13, quantity 2, src 192.168.178.85: Error finding service with device type vebus at device instance 512
Any ideas?
Greetings
Christian
Hi @dragonfreak
The error code seems to suggest that you're trying to get address 13 on Unit 225.
When I look at modbus TCP registers I can see address 13 is Input power 2 (as in L2 on ACIN). I might be misunderstanding but i think the address might just be incorrect?
Battery (Unit ID 225) only support adress range 259 ... 326!
Hello Christian,
which cable did you use to connect to Cebro?
I'm also stuck on a Pace BMS.
What setting did you choose here?
Thanks
Klaus
