Emergency Light, decoding of status

[chriscroko]

Use this script:

Code:

hex = event.datahex
bytes = {}

for i = 1, 6 do
  pos = 1 + (i - 1) * 2
  ch = hex:sub(pos, pos + 1)
  bytes[ i ] = tonumber(ch, 16) or 0
end

ltrf = bit.band(bit.rshift(bytes[ 1 ], 4), 0x0F)
ltrd = bit.band(bytes[ 1 ], 0x0F)

ltrp = bit.band(bit.rshift(bytes[ 2 ], 4), 0x0F)

sf = bit.band(bit.rshift(bytes[ 3 ], 6), 0x03)
sd = bit.band(bit.rshift(bytes[ 3 ], 4), 0x03)
sp = bit.band(bit.rshift(bytes[ 3 ], 2), 0x03)

ldtr = bit.bor(bit.lshift(bytes[ 4 ], 8), bytes[ 5 ])

lpdtr = bytes[ 6 ]

log(ltrf, ltrd, ltrp, sf, sd, sp, lpdtr)

The script works and logs the right datasets. What I need now is a way to write out the different parts to different group addresses for BMS purposes. Could you give a hint on how to do this also? 

And also thanks for the base script.
