If you need to transfer the driver to another Control4 controller, the license key needs to be reset. Please email us at firstname.lastname@example.org and include your license key and we will reset it for you within 24 hours.
Once your key is reset, then you simply need to activate it on the new controller, and then perform a reboot of the controller in order to restore your trigger events and programming.
We have found that the easiest thing is to use an IP Scanning utility- preferably Advanced IP Scanner, or the Fing mobile app, to determine the IP of the Echo. To be sure you are looking at the correct device, you can cross-reference the device's MAC address with the MAC address shown in the Alexa app (under Settings -> <Your Echo Name> -> MAC address is shown at the bottom of the settings screen.
Yes. One license key covers your entire Control4 project, regardless of how many Echos/Dots are being used. Echos can be either registered under the same Amazon account, in which case they share Triggers, or they can be registered to separate Amazon accounts in order for each to have its own set of Triggers.
One driver instance is required in the Control4 project per AMAZON account, not per Echo.
