I am connecting a "Janitza UMG96RM-E" device to a Windows Laptop where I am using Hyper-V to use Linux cmds. I registered the Laptop as an Edge device and added Modbus to the set of modules. I read the Janitza documentation (start Address, nbre of bits ...) and I Added the correct Ip Address the Module Twins file... Everything looks heathy except I am not receiving any data from the Modbus module... I am not able to figure out what is wrong ? Here is some logs from edgeHub module.

Here are the info that I used from the Janitza docs to configure the Module Twin: Modbus address list
I have found that the problem was the register start-address that I am reading from. In my case I had the add a 4 in the beginning (Holding Register) and +1 in the end. example: if in the documentation of the slave device I can read the Power from the address 19000 : in the Modbus Module twin I specify the address to be 419001 ! I hope this can help people in the future.
