Restarts node-red

[nomadbeni]

If the yeelight is offline and a command is sent to the device, it says: UnhandledPromiseRejection....... which is good, because the yeelight is offline.
But when the yeelight comes online, it restarts the node-red, which is not good.
I attached a screenshot of the message.
Once it continuously restarted node-red untill i stopped it and deleted the yeelight node in the command line.

Thanks for report. Will try to fix it asap. But probably not earlier than on next week unless you make pull request.
Busy at work :(

Hi,
I have a similiar problem. If the Yeelight is offline och the IP-adress have changed, Node-Red got stuck in a restart loop and even managed to crash the installation on my Raspberry Pi -> Reinstallation from scratch.
I got this from syslog:

Fixed the issue.

#3

Could you please confirm that the latest version fixes the issue?

Thanks to @HendrikRoth who made the fix

[HendrikRoth]

The main fix was to wrap the method in an try/catch block. i updated to the latest version only to be up to date.

Well
I tried it. This happened:

Hi, I have also tried the new version and as long as the Yeelight bulb is online, everything works well but if I cut the power to the bulb the same behavior occurs as before with approximately 2 restarts

of Node-Red per minute.
I enclose a new syslog that covers 3 restarts

Could you please test 1.0.4 version in several cases:

• starting node-red when yeelight is offline
• starting node-res when yeelight is online
• turning yeelight offline when node-red is running

I can't test it on hardware tight now :(

[nomadbeni]

I will test is on saturday and post the log.

Timing out and crashing :(

Unfortunately the flow that worked with 1.03 won't work with 1.04 for me :-(
I have rebboted the RPi, but same result.
The good news is thas Node-red won't restart anymore if a turn off the power to Yeelight.

Same issue here, updating from 1.03 to 1.04 completely broke all nodes for me :(

[nomadbeni]

Same with me.

[LolCatPhd]

Getting the same error as well.
1.04 broke all nodes.

Any clues whats wrong?
