When my power comes back on, it seems the Policy seems to boot too fast and I get the message ISY994 not found on network.  If I reboot the polyglot all is fine.  I checked it, because some Hue lights were not responding to ISY commands to the Hue node.  Rebooting the polyglot fixed that and the error message.

It seems like there should be a retry, or the delay option on the Policy.  Or can someone recommend a device to delay power after a power outage?

Lore. I had the same issue with my setup.   I added an Aeotec zwave Smart Switch 7 with the parameter set so when re-energized, it would come back in the off position.   Then I had an ISY program turn the switch on after the ISY stabilized to energize my Polisy.  Works great. 

Hope this helps

You might want to consider running ISY on your Polisy.

Does that work?  I mean both the ISY on Polisy and the ISY starting before the Polyglot?

I've been running ISY on Polisy (IoP) for some time now. After a power loss everything starts up fine. Once in a while I may have to restart a node server - that's it.

I'm a bit worried ISY on Polisy will be some work and won't solve my entire problem, especially if my loss of Hue lights was caused by the Polyglot Hue Node starting up before the Hue Hub was fully booted.  What I think I really want is a power up delay for the Polyglot Nodes, so what they talk to has a chance to boot.  Maybe just put a long sleep in the startup script or something.

I don't have any Hue devices, so I'll leave it to someone else to chime in here.

Or - is there a way for your Hue hub to be put on a delay, or to restart again after a power failure?

You could use an Insteon OnOffLinc plug-in with an ISY program that turns off the power each time it boots up and then turns it back on after a minute or so.

Better yet there may be a way to monitor the Hue Hub and power cycle it when no response is had.
