dgeffs,
If you have HS2 and Stargate plugin running, and have Stargate devices populating HS2 devices, you are 80% home already.
Follow the excellent installation instructions for MLHSplugin. Our good friend BSR and the developer Krumpy did a nice job on the install documentation that always gets thumbs up from people that have used the docs to setup the plugin(s).
High level:
Download the MLHSPlugin from Homeseer2 Updater (web page)
This will install the Homeseer side of the plugin pair. The other side gets installed as a plugin in MainLobby Server (MLServer). Install MLServer (download from Cinemar website). Install MLHSPlugin in MLServer. Enable the MLHSPlugin in Homeseer. Subscribe to device A1 (or others).
Install MainLobby client on same PC as MLServer. Enable MLServer and use all default ports. When you launch ML client, make sure you see it in the MLServer Client configuration window. It should say localhost. Now the client and MLServer are talking to each other.
Homeseer MLHSPlugin should now also be talking to MLServer MLHSPlugin. The Homeseer side should show "connected".
Add a button on MainLobby client stage. Edit the button. In the label field, add {{mlhsplugin_A1_value}} Click OK, Click Launch, Click Save. You should now see whatever value is assigned to A1 in Homeseer (could be Off, On, or a numeric, or text, or whatever). Go into MLServer and click on the Variables button. You should see the A1 variable and it's value. That value should be same as what is showing in MainLobby client button.
Let us know how it goes!!
Then the fun begins while you get absorbed into building your neat scenes that look great, meet your individual needs for function, navigation and style. It gets addicting where you will want to spend the time. That is if you enjoyed Lincoln Logs or Erector sets as a kid
