modbus is a universal interface? #10

Closed UberChmonya closed 1 year ago

UberChmonya commented 2 years ago

the name of my VFD is Delta VFD015EL21A. Will it work?

Modbus is a communications protcol so yes it is universal. However each VFD vendor implements their own messages on top of that so a separate plugin is needed for each VFD (or each VFD vendor depending on whether they have standardized the messages across models). Adding a plugin is not too hard if documentation is available. There is a PR for further VFDs pending, I will soon review that for merging. This may give you an idea of the work involved.

If your VFD supports true modbus you can very likely get it working with the MODVFD mode from the above PR.
