I have Node-Red monitoring and controlling a number of devices over MQTT. So I have a byte that returns the status of 8 relays (on or off). Is there any way to break that down to 8 outputs that can drive indicators on the NR dashboard? I've searched the net over the last few weeks and cannot find anything. The closest would appear to be a switch node. Go easy on me, I had to retire at the lockdown so have been learning this since then. 🙂

Hmm I'm sure there is a node for that - there is this one that does 16 and 32 - maybe it also handles 8

That's perfect. Works straight out of the box. Thanks for the help, appreciated.
