Dave, I have just setup a local thingspeak server on ubuntu, didn't realise you could do this until I saw the option in your plugin and its great that you can given my poor internet connection. Anyways, the local server setup installs and does not use SSL, so I get an error when uploading data
* Trying 192.168.0.75...
* Connected to 192.168.0.75 (192.168.0.75) port 3000 (#0)
* WARNING: using IP address, SNI is being disabled by the OS.
* Unknown SSL protocol error in connection to 192.168.0.75:-9847
* Closing connection 0
Any ideas ?
