307.1 roomnode feedback

I have tried the 307.1 beta and while the 20x4 lcd works wonders for me, I am having problems with the temperatures and light levels feeding backfrom the roomnodes.

roomnode[2] is working ok for temperature, thanks goodness as that one controls the central heating but the light level feedback is erratic.

roomnode[3] is showing my conservatory at 20C + and I know it's not that warm ;)

roomnode[4] is my gas monitor and I am using the humi to store the pulses from the meter and previously I was getting 11 pulses max per transmit cycle, now I get 64 :) oh and it's 23C outside, time to sunbathe :)

I know there is the toff and toff2 offset I can now add but excuse me for being stupid but where do I add it?

rolling back to 307 as that works fine (thanks Brett)

I have tried looking for differences between 307 and 307.1 but I can see nothing that would cause this
