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?

You can try adding

continue_on_error: true

to the scene action so it doesn’t kill the entire automation. Note that if later parts depend on this action then they’ll fail in weird ways. The best thing is to fix the Zigbee network so the device doesn’t drop off but I know that’s not easy.

I might give this a try while I work on the actual underlying cause. The rest of the automation isn’t impacted. It just turns the lights a color when it starts, then resets the color when the automation finishes.
