I happened to stumble upon this thread and noticed a striking similarity between the Modbus descriptions in both this threads and this one.
As the author of the Dantherm integration, I don’t see any reason why it shouldn’t also work with Pluggit units as well as the Dantherm units. Even the apps from both brands show a noticeable resemblance.
Check out the linked discussion, and if anyone is interested in testing the integration, I’m considering creating a separate Pluggit integration using the same code.
