VRV STATUS VIA BACNET

[imprashant]

You are using bacnet client script so you cannot be bacnet server.
Use direct communication script if you use multiple event scripts.

Code:

require('bacnet')

-- read from 192.168.0.21, device id 21
bacnet.deviceip = '192.168.0.21'
val1 = bacnet.readvalue(21, 'binary value', 2049)
val2 = bacnet.readvalue(21, 'binary value', 2050)
val3 = bacnet.readvalue(21, 'binary value', 2051)
log(val1, val2, val3)

For reading use single resident script.
Use Yabe to check parameters of object you want to read.

Thank You. How can I write the log values to the group address only if there is a change in value?
