Hi there.
Basically for Z-Wave there is a Ping action you can use for reliability purposes (.e.g polling some of the nodes that a tend to go dead, or slow to respond if not used regularly, so pinging them keeps them “hot” and alive).
What I see for my Nanoleaf Thread Bulbs, is that some of them go unavailable, but if you ping them, they go back to be available quite often a 2-3 seconds after ping is finished.
What I wanted, is to make automation (probably in Node-RED) that when light node becomes unavailable and is a Matter light for a minute, I would trigger a ping that will likely heal the bulb.
And will do the same thing but on 5 minutes polling, to check all unavailible Matter nodes, and ping them proactively keeping my lights much healthier.
Thanks.
