HI,
I have a Multiplus 2 with latest firmware, an MK3 thats new and a Cerbo GX running Firm 3.01.
The Cerbo and the M2 run fine passing data back and forward all day as they should on the VEbus. However when I connect the MK3 to the M2 to do some "tweaks" (still learning and fine tuning) about 2 minutes after the MK3 is connected the M2 goes off line with a Low battery fault. My assumption is the Cerbo is no longer talking on the VeBus when the MK3 is used. My BMS talks to the Cerbo via Can bus.
I notice in the Cerbo it states its VE.bus address is 1, I assume it has to be this to be the master. I then subsiquently assume the MK3 is also 1 as it needs to be the master to communicate with the rest of the network. Is this correct or can I change the Cerbo to be Add 3 and all should work (assuming the M2 has picked up add 2 on the VEbus.)
