Hey there @janiversen, mind taking a look at this issue as it has been labeled with an integration (modbus
) you are listed as a code owner for? Thanks!

modbus documentation modbus source (message by IssueLinks)
This is not a bug in the modbus integration!
your device is not responding, maybe because you use a wrong framer.
Closing as not being a bug,
Any hint where I can get some help? Thanks!
This is not a channel for support, only for bug reporting...try the user forums.
Root cause of my problem was my abandoned MBus project. The wMBus Addon tried to communicate over the USB to Modbus-Adaptor at /dev/ttyUSB parallely to the Modbus Integration. As soon as I stopped the wMBus Addon, data could also be received. Turning the wMBus Addon on again replicates the error of no data received.
Of course the usb adapter cannot be shared. Closing
The problem
With the HA-Modbus Intergration no data can be recieved from Danfoss ECL Comfort 210. Modbus Error: [Invalid Message] No response received, expected at least 4 bytes (0 received)
When I hook up the serial adaptor to my Windows PC and using the Software "Modbus Poll" the data can be recieved. The settings in the two systems seem to be comparable to me.
Thanks, for any help to get this running!
