This is the basic on/off control flow. Note that I've tweak the location in the CRON+ node. Also, I use the root MQTT topic shellies for the Shelly devices - not sure if that is the default. The 2 MQTT in nodes "Rmt n, Btn b:2" are indirect outputs via my RFXtrx433 dongle listening to LightwaveRF remotes. The mini-flow bottom-right simply refactors the on/off setting to a different MQTT topic structure.

Here is the Dashboard flow that was my prototype - remember, this is D1 not the newer FlowFuse D2.
This is just the Office part of that flow:

This is what it looks like:
As I mentioned, I don't really use either of the Dashboards. Unfortunately, my live home dashboards lighting page is currently due for a facelift and nothing is currently connected, but here is a preview:
Imagine each of the named room cards containing controls for the lighting not dissimilar to the Dashboard example.
Honestly, I so rarely use the lighting page that I've not a lot of incentive to finish it right now, too many other draws on my time. My lighting is entirely automated where it needs to be so very little reason to muck about with a web page.
