Writing setpoint 8bytes

[admin]

Here's how to combined 4 separate object values into a single object:

Code:

addrs = { '1/1/1', '1/1/2', '1/1/3', '1/1/4' }
value = ''

for _, addr in ipairs(addrs) do
  val = grp.getvalue(addr)
  enc = busdatatype.encode(val, dt.float16)
  value = value .. enc.dataraw
end

grp.write('1/1/5', value, dt.raw)

This will work over KNX/IP but not over BACnet. Each BACnet datapoint can only store a single value.
