@timovd you should support both values, don't think that everyone will upgrade it soon :)

Indeed we need to realize a discover function to select either/or. It should not become a breaking change on HA Heishamon side

see #131 (comment)

If you're on fw <=3.1, you should use the old version of the integration. You cannot support all values forever.

Not so sure about that. People install HA, HACS and the Plugin being interested in onboarding Heishamon. And then per default/latest Version it does not work. Lots of complaints and issues will be raised.

Heishamon is often bought out of the box, I bet a significant portion of people do not know FW can be updated

FW 3.2 was released 2 days ago!
So I intend to keep compatibility with 3.1 and previous versions for some time (at least until I update my heishamon and probably for a lot longer).

AS @Bucky2k wrote, people can upgrade HA and custom integration very easily. Upgrading a firmware is not the same thing.

Anyway, thanks for the contribution. I think I'll merge as is this week end and add a patch to be backward compatible with version <= 3.1.

This discussion also gave me the idea of #133 which I hope I'll be able to implement in order to give a nice nudge for updates.
