hello, Can you help mi with connection my Cerbo GX with Loxone via modbus TCP? Cerbo is connected on my loccal ethernet with cable, I would like to some how connect Cerbo to Loxone.
The idea is use the same ethernet cable on cerbo side and use Modbus extension on Loxone side.
Or another idea?
THX
Martin
Hi Martin,
I’ve linked the Cerbo to loxone here. You can just use modbus over ip, no need for the modbus extension or any other hardware, they just need to be connected to the network. There are templates available in the loxone library so you don’t have to figure out all the registers:

Hi,
Thanks, I going to read it and try to set up everything.
Hi,
One extra question, I have my data from victron in to the loxone, but during the day when my meter is counting minus value (feeding to grid) Loxone is receiving just plus value.
Do you have a idea why?
Martin
You mean the 3 ac consumption blocks in loxone ? Those are the ac consumption values, not the grid values. Ac consumption cannot be negative.
If you want your grid values, you need the Grid L1, L2 and L3 blocks with addresses 820-822.
Yes I would like to read grid values, positive and also negative. My Grid L1,L2 and L3 are set up correct with this addresses.
So you see the negative values in loxone using live view, but your meter is not showing them ? Did you use a bidirectional meter block in loxone instead of the regular meter block ?
No, all my problem is I don’t see negative value in Loxone during the day. Yes I used use a bidirectional meter in Loxone.
I made some changes in configuration, I will check it tomorrow during the day.
Hi, I fixed it, the problem was with wrong set up bit integer. Instead of 16-bit signed integer I had set up 16-bit unsigned integer.
Thanks for you help
