First, get the updated Weaved connection daemon onto your plug.
SSH to the Plug, then:
To be nice, gracefully shut down the existing daemons. You should be connected using the IP address on your LAN rather than the Weaved proxy URL at this time, or else you will lose connection as soon as the SSH daemon terminates!
Now rename the new daemon to take the place of the old one:
mv weavedConnectd.mips-openwrt-plug connectd
chmod +x connectd
Restart the daemons:
In the iOS application, find the name of the Web connection for your plug in the device list. Tap on the right arrow on the right hand side, then enable "Send Notices" under "Alert Options".
Back on the Plug, send a notification to the Web connection using the following command:
connectd -f /etc/weaved/weaved-http.conf -note 1 "The Plug is sending you a message!" "Ok"
The parameter following "note" can be 0 or 1:
0 - unencrypted
1 - encrypted using RC4
The final string on the command line, "Ok" as shown here, is simply what is shown on the console when the message is sent successfully.
You can see the notification events in the Alerts list area of the iOS client.
