Hello MySensors community.
I'm using OpenHAB MySensors binding 2.5 and would like to have my node (window cover controller) send a string on one of the V_VAR channels e.g. V_VAR5 back to the controller.
Intention:
Basically whenever I send a command to the node from the controller I intend to send a "reason" (or mode) to the node along with the command itself e.g. "Closed for sun protection" or "Closed for sleeping" or "Opened due to sunrise"...
This reason should be kept on the node and send beck to the controller on request e.g. after a restart of the controller (as a response to a message of type = C_REQ).
This way I could restart the controller and have it not only request cover positions but also the reason (or mode) that brought them into that position.
Problem:
My problem with that is that apparently the OpenHAB MySensor binding does only support numeric values being transported from the nodes to the controller via V_VAR1 - V_VAR5 channels even though the Serial API of MySensors does allow string values for V_VAR1 to V_VAR5.
Is there a solution to that problem, should the binding be changed?
How else could I achive what I'm trying to do?
Here's the log entry of the request I'm sending from OpenHAB rule to the node:
2020-06-03 21:04:00.518 [DEBUG] [rsAbstractConnection$MySensorsWriter] - Sending to MySensors: 7;4;2;0;28;
And the log entries (errors) caused by the nodes response (the node sends the string "initial"):
2020-06-03 21:04:00.548 [DEBUG] [rsAbstractConnection$MySensorsReader] - Message from gateway received: 7;4;1;0;28;initial
