But is there an item I can add to an item group for the same thing? As lately I have only been adding group names to my site map and just displaying everything for that group…it’s makes sitemap management much simpler:
eg
Group item=g_shelly
Which conains two groups:
Group g_shelly "Shelly Devices"
//----------------------------------------------------------------------------------------------------------------------
// Ballroom Shelly Humidity and Temperature Sensor
//----------------------------------------------------------------------------------------------------------------------
Group g_shelly_ht01 "Shelly Temp and Humdity 01 (Ballroom)" (g_shelly)
Group g_shelly_ht02 "Shelly Temp and Humdity 02 (Lounge)" (g_shelly)
So Idealling I want to add an item to the group that I can set to the grafana chart that will just appear under the group page for the sensor.
But you have absolutely no ability to customize when using Group elements on the sitemap.
Image is not the default element for any Items except for Image Items. So you could theoretically create a Group of Image Items and put that Group on the sitemap using the Group element. But that only moves the problem as I’ve no idea how one would get the Grafana generated images into an openHAB Image Item. It seems like that should be theoretically possible but I don’t know for sure. I never used Image Items with Grafana and have stopped using Grafana at all since moving to OH 3.
Sitemaps are pretty much all or nothing. Either you define each element yourself and have full control over what and how things are rendered. Or you use the Group element and you have almost no control over what and how things are rendered.
But you can’t do that. It’s an Item, you have update the state like any other Item, from a binding channel or by postUpdate() from a rule.
There’s an HTTP binding of course.
