Code are need some edit.
Set your SSID Network and Passwoard.

ThingSpeak https://thingspeak.com/

Make your TalkBack Command to control deives.
and make your Channel for show your Data.
Getting Start with ThingSpeak  https://thingspeak.com/docs

ThingSpeak TalkBack API
 To control devices use TalkBack API Command.

GET TalkBack Command

GET https://api.thingspeak.com/talkbacks/2225/commands/XX?api_key=1234567890ABCDEF

xx = COMMAND_ID ( 00 - 99 )


UPDATE TalkBack Command

PUT https://api.thingspeak.com/talkbacks/2225/commands/XX
    api_key=1234567890ABCDEF
    command_string=OPENDOOR
    position=5
