HDMI Sync Box

Anybody set up the Sync Box on their SmartRemote? There isn't a driver for it so I had a mess round with Home Assistant and I can see it under the HA driver but I'm not really sure what to do from here.

Any help would br gratefully received

 

Just thought I'd try again. Anyone managed to set this up? 

I'm looking to add this server variable from the Home Assistant Driver to my satellite and shield. I'm assuming it will go into the respective macro's so it il switch to the right input.
my 2 devices are connected to the Sync Box which in turn is connected to HDMI1 on my TV.

Home Assistant  does this perfectly. The "How to" on Home Assistant saysmyServer variables versus Home Assistant entities.If you click on the right arrow button next to any device in the driver you will see all the server variables that have been associated with that device. Here we show the variables for the Great Room Lights. Notice the we track both the myServer and Home Assistant sets of variables. The variables that start with the family name and an underscrore are the set of myServer variables. The other variables are equivalent to the Home Assistant entity values. You can use any of these variables in myServer. Both sets will be updated in realtime as soon as they change in Home Assistant.

The home assistant server variable looks like this

select.sync_box_hdmi_input_options 

and I'm not sure what to do with it. I did just copy it into a macro but it didn't work and gave me this error

Unknown command select.sync_box_hdmi_input_options

Thanks in advance
