p.s. Also, you have the inner hybrid and outer hybrid temperature sensors at the 
same address. Of course that does not work -- please change this ASAP for the 
new outer hybrid design before it gets forgotten. For prototyping with the 
existing hybrids we will have to hack this, should be possible.
