I believe the Mirror App was written to aid in the use of controllers like the Lutron Aurora One
This device is similar in functionality to a dimmable bulb, but is used to control other lights by having its status mirrored to another dimmable light via the Mirror App.
I am having a problem synchronizing two bulbs to the exact color. Although I send the same command to both bulbs one is always slightly off. Can I use the mirror app to synchronize the color, temperature and level?
Suddenly the lights appear to be synchronized. I have been trying to replicate the problem, but all is working well now.
Here is the rule that I am invoking
My $0.02: if you are using Zigbee bulbs and want them to always be in the same state, add them to a Group and enable Zigbee group messaging.
Then, you get a new device that represents the Group, and all commands and actions execute simultaneously instead of having to catch up with each other via the Mirror app.
Is there any chance of improving upon the Mirror app to mirror thermostat controls. I have a unique situation that I would like to take advantage of without having to write a series of very complex rules.
Mirror me is really specifically built for lights and switches, as such it's really not going to do well with thermostats.
Your best bet on this is going to be a dedicated custom app to do exactly what you want.
