thanks @ssalonen ! played a little bit more and found that I was needed to adjust the registers in order to read the “right one”
Adjusted to:
Bridge modbus:tcp:HVAC [ host=“192.168.8.199”, port=502, id=1 ] {
//Register-902 Supply temperature RO signed short -500 - 1200 x10 C
//Register-903 Extract temperature RO signed short -500 - 1200 x10 C
Bridge poller holdingP1 [ start=901, length=1, refresh=2000, type=“holding” ] {
Thing data holding1 [ readStart=“901”, readValueType=“int16”, readTransform=“JS(divide10.js)” ]
}
Bridge poller holdingP2 [ start=902, length=1, refresh=2000, type=“holding” ] {
Thing data holding2 [ readStart=“902”, readValueType=“int16”, readTransform=“JS(divide10.js)” ]
}
}
and get nice readings:
2017-12-27 20:22:29.925 [vent.ItemStateChangedEvent] - holding1 changed from 19.1 to 19.2
2017-12-27 20:23:17.126 [vent.ItemStateChangedEvent] - holding2 changed from 21.5 to 21.4
And the last question related to Register readings: say I have below named in the manual:
Registers 906-907 “Current supply flow” RO unsigned int 0 - 200000 m3/h, l/s
how I should make my Number item to store this data read from 2 registers (906 and 907)? should I combine it somehow? sorry, I’m new - that’s why asking.
