Hello,

this is my first post here.

I have a running instance of OH2 that does control mostly KNX and Z-Wave devices. BasicUI working, also remote access through myopenhab.org. 150 items in total.
So far everything perfect.

I intend to set up a smaller second instance for my holiday home. Only Z-Wave plugs and radiator valves. Won‘t be more than 20 devices. The holiday home has a permanent DSL connection.

My iOS app will only work with one myopenhab.org access at a time. Means: setting up the second instance would need to constantly change credentials in the app to connect. Makes no sense.

Further, I understand, I cannot connect from both instances with the same credentials and uploading two different Sitemaps. „main“ from home, „vacation“ from the holiday home.

I would rate myself not-too-rookie with OH2. But in this situation I feel I need to install a different system (Home automatio perhaps) in my holiday home just to avoid switching between credentials in the iOS app. Of course I can have only one instance of the app on my mobile device.

To bring it to the point: I am kind of clueless. I would prefer to go with openHAB, but have no idea how to set this up in my situation.

I appreciate any hint on how to continue. Perhaps you have some advice where to look.

Thank you,
Hanns

You can use MQTT between your OH instances, having one “primary” which receives all status. And then just add your items to the primary sitemap. At least that’s how I do it…

Oh and support this one :wink:

You could also login to on myopenhab in the browser and one in the app.

A not perfect but quite simple switch between them.

Thanks! I am testing MQTT, but this is a strange syntax, at least to me.

this would mean using a second myopenhab login, correct?

Yes it would.
