New Developer trying small mod to existing code

Ahh, another attempt at “fixing” The Flasher…
FWIW, here is the link to ST docs on Closure. IMO though, this endeavor is doomed to fail. I’ve been down this road before. It’s not that the app fails to restore state, but that cloud latency causes some of these short duration events to be “eaten.” I think the protocol-specific “delay” method described by @bravenel (below) is a better approach, and likely to be much more reliable:

[OBSOLETE]How to makes lights Flash (code for DTH modification)

It is possible to add a custom command to either z-wave or zigbee device handlers to make them flash when commanded. Once the custom device handler is created and published, you can edit the device you want to flash to use that device handler. After that, the flash command can be exposed in Rule Machine Create Custom Commands, and used as an action in Rule Machine. For either type, add this line in the metadata: command "flash" For a zigbee device add this code: def flash() { delayBetween ([ delayBetween ([ zigbee.on(), zigbee.off()], 1000), delayBetween ([ zigbee.on(), zigbee.off()], 1000), delayBetween ([ zigbee.on(), zigbee.off()], 1000), ], 1000) } For a z-wave device add this code: def flash() { delayBetwee…

For 100% reliability, consider replacing your smart switch with an Aeon microcontroller. These cost about the same as smart switches, but have a firmware controlled flash and strobe capability in addition to the normal on/off. The Aeon units can be used with a regular “dumb” switch or their own touch-panel, thus allowing you to re-purpose the smart switch being replaced.
