** for now, after successful pairing, set /var/lib/openhab2/jsondb/homekit.json read only after successful pairing. May have to undo to re-create a new pairing
* after a reset of the openhab server, it may take quite some time for homekit to attempt a reconnect to the server. You can force a reconnect by putting the iPhone etc temporarily into and out of airplane mode. This forces homekit to reconnect
=== Alexa setup ==
* Install the openhab cloud connector in add-ons -> misc. This will create a UUID and secret that we need for hitching up to the openhab cloud. In the background, it already attempted to log on with the created credentials, but fails (since there is no account on myopenhab yet), and will not attempt to go any further. As we'll see, this creates a bit of a problem later.
* get the UUID and secret from <pre>/var/lib/openhab2/uuid</pre> and <pre>/var/lib/openhab2/openhabcloud/secret</pre> and create/sign on at http://myopenhab.org
* myopenhab needs to verify email address, do so...
* '''Tricky''': myopenhab will still say that your openhab instance is not connected. This is b/c a earlier attempt by the openhab server failed, and now it has given up. Go back to paper ui, configuration -> services -> openHAB cloud and hit configure. Just hitting "Save" will retrigger the log-on process, which should now be ok.
