Best way to wire NRCHB parallell with Node Red Dashboard switch?

[houser42]

Hello,
Would appreciate some help with the attached flow.

The flow works but is a bit of a hack and I would appreciate a hint or two of how you would do this to optimize it.
It is simply three switches wired in parallell. One for Home kit, one for the Node red dashboard and one for a physical Shelly relay. All serve to switch the Shelly the same way.
A physical moment switch at the Shelly and the two soft switches should switch it the same, and also reflect a change anywhere between the three of them, yet not create a loop. I am unable to come up with a clean and robust solution. But again, this appears to work, so is perhaps a half-decent way to at least show why I am trying to do..

Can you suggest a cleaner and more robust way of doing this by any chance? Many thanks!

I took a quick look at this, it looks pretty good to me. I don't see anything "wrong" with it if it works.

Since you want two user interfaces (homekit and dashboard) then you'll need to build them each in parallel as you've done. I can't test this for real since I don't have any shelly device, but it looks like a good setup.

Hello @crxporter , appreciate the reply!

There seems to be some theoretical risk for a loops, as the only one of the nodes that has a "do not pass thru" function
is the NR Dashboard one. But like you say, it appears to work...just don't feel confident about the robustness of the programming.
And as it is in a remote site, that might cause some problems.

The homekit node has a disable pass through option, it is in the bridge configuration panel (screenshot below). But if you're using the "top" output of homekit, it only outputs changes so it won't repeat on or off messages. Would only just send one then be quiet.

Very useful info. Many thanks!
