API chaged by Thermia

[fclauson]

Not sure if it affects the code used here (but I used a hacked version of this running behind a google sheet)

they chaged 2 things this week

they added a "2" to the front of my installaiton ID
they reverted the registerID and registerIndex to the way it used to work - this has the effect you have to put "10" in front of some registers

as I say - not sure if its a problem with this code but the API has definatly changed
I WISH THEY WOULD EMAIL USERS TO SAY THEY ARE MAKING THESE CHANGES
