Automation being broken by a disconnected light timing out?? (sh.itjust.works)

I have an automation that when triggered turns on a scene that sets my lights a specific way. Then the automation waits for a second trigger.

I noticed that the automation doesn’t continue after the second trigger, so I looked at the trace, and it looks like the scene setting step of the automation times out: “error: Timed out when calling async_turn_on for bulb xyz: <class ‘TimeoutError’>

It looks like this bulb xyz was dropped from my zigbee network, which isn’t always the most stable. So it’s not exactly uncommon.

So how do I safeguard my automations from being broken by a single piece of a scene being offline?

Also, since zigbee is a mesh network, the fix could be as easy as adding a smart plug halfway between the controller and the light. Every zigbee device not running on battery works as a repeater too

    FYI: not all mains powered devices are routers, I have some light switches that are end devices only.

    But in general, yes most mains powered devices are routers and will help with getting the network to reach

    I think I've mostly run across that with "no neutral" switches FWIW. It was confusing for a bit when setting up my garage.

    Also very frustrating info to try and track down when buying sometimes.
