Modbus wrong readout

Configuration
1

I have two identical ND meters. When I Read holding register 515. One of them reads correctly, but the other gives me an odd negative value.

I’ve checked the direct reading from the ND device, and this shows correctly, but not in HA. Any ideas why. The Register 515 on device 40007 works fine, 40008 gives weird value.

Any Hints?

Since the 18, the value of the Register has increased, and now Ha shows -9500, this is consistant with the increased value from modbus register. So it seems like it reads the value correct, but count’s from a wierd set point. Tried setting the state to 0, tried clearing the statistics. But with no luck at all.

Any ideas ?
