Is there a Dashboard matrix switch

[m_elias]

I was daydreaming the other day about a generic wireless mqtt hardware switch panel that could easily be moved around and be reconfigured to switch different devices. What’s the most convenient way to change the mqtt topic or redirect the payloads coming from this switch panel?

I wondered if node red has a matrix switch dashboard node.

Consider Node-RED as a tool box. I'm sure you can build it using all possible available nodes and features (i.e. javascript code in function nodes if required). Sometimes you will even find other peoples examples very close to what you need, at least gives you the ideas. But the work to do is still yours in most cases

I feel my question is misunderstood. I'd rather not re-invent the wheel so to speak if someone else has already done it, maybe I just don't know the correct terms to search for. Maybe "crossbar-switch" is a better known term. I'm asking if there exists a UI node that can handle easily selecting which MQTT "input" topic is linked to an "output" topic in a crossbar/matrix type of setup. I know how to do it manually with mqtt in & out nodes but to edit those with a mobile device would be quite clumsy.

@m_elias,
I don't think something like this will exist yet.
Do you have any screenshots with examples of how it should look like in your dashboard? Perhaps then somebody can give you some ideas of how to get started..

4 instances of @BartButenaers' own node-red-contrib-ui-multistate-switch is perhaps the closest match.

Each line independently acts like a radio button - only one selection possible.

Or something like this

Each incoming message can be routed to zero, one or multiple outputs.

Add more switches and message routes as needed.

This made me curious so I played for a bit. I went on the idea that if S13, S21 and S31 are on and you turn S11 then it should shut S13, S21 and S31 off.

So here is a flow that will do that
