Temperature value

Seems the scales have been incorrectly set in emonhub.conf

openenergymonitor/emonhub/blob/v2.1.2/conf/emonhub.conf#L140

    
      
                 names = power1, power2, power3, power4, vrms, temp1, temp2, temp3, temp4, temp5, temp6, pulse
                 datacode = h
                 scales = 1,1,1,1,0.01,0.1,0.1, 0.1,0.1,0.1,0.1,1
                 units =W,W,W,W,V,C,C,C,C,C,C,p
          
          
[[11]]
              nodename = 3phase
              [[[rx]]]
                 names = powerL1, powerL2, powerL3, power4, Vrms, temp1, temp2, temp3, temp4, temp5, temp6, pulse
                 datacodes = h,h,h,h,h,h,h,h,h,h,h,L
                 scales = 1,1,1,1,0.01,0.1,0.1,0.1,0.1,0.1,0.1,1
                 units =W,W,W,W,V,C,C,C,C,C,C,p
                 
           [[12]]
              nodename = 3phase2
              [[[rx]]]
                 names = powerL1, powerL2, powerL3, power4, Vrms, temp1, temp2, temp3, temp4, temp5, temp6, pulse
                 datacodes = h,h,h,h,h,h,h,h,h,h,h,L
                 scales = 1,1,1,1,0.01,0.1,0.1,0.1,0.1,0.1,0.1,1
                 units =W,W,W,W,V,C,C,C,C,C,C,p

The raw (x100) temp reading are being divided by 10 in emonhub so they land in emoncms x10 (all 4 templates are apparently wrong)

The sketch source seems correct

emonhub.conf node decoder settings for this sketch:
          
          
[[11]]
              nodename = emonTx_three_phase
              firmware = three_phase
              hardware = emonTx V3.2/V3.4/Shield
          [[[rx]]]
              names = power1, power2, power3, power4, Vrms, temp1, temp2, temp3, temp4, temp5, temp6, pulsecount
              datacodes = h, h, h, h, h, h, h, h, h, h, h, L
              scales = 1,1,1,1,0.01,0.01,0.01,0.01,0.01,0.01,0.01,1
              units =W,W,W,W,V,C,C,C,C,C,C,p
          
          
IMPORTANT NOTE:
          When used in the 3-wire configuration with one line conductor being treated as the 'neutral', the
          individual powers recorded for the other two line conductors are meaningless, only the TOTAL power
          of the line conductors has a physical meaning. Therefore, 'power1' is the COMBINED power of inputs 1 & 2
          and all the values for input 2 alone are set to zero.
          Note also: Only one temperature sensor may be connected. All remaining temperatures will read "300.00"
          
          
For serial input, emonHub requires "datacode = 0" in place of "datacodes = ...." as above.
