questioun using multiple sensors on domoticz

Hi guys i building a multi sensor node , but i have one problem with a water pressure it keeps giving me a weather pressure , any one know what im doing wrong

any help will be very appreciated

@fernando-alvarez-buylla S_WATER is a Volume or Flow subset from memory.

I've not yet got round to installing pressure sensors on the pumped supply, but had already settled on tracking numeric values of hydraulic pressure such as Bar or Metres typical of physical pressure meters, so V_DISTANCE and S_DISTANCE seem more appropriate and might be worth a try your end.

@fernando-alvarez-buylla said in questioun using multiple sensors on domoticz:

S_WATER

Here you will see that with S_WATER you should use another V-TYPE:

@alowhum Always been curious how Domoticz treats the V and S values, so tended to follow the MySensor API and had a few if unexpected moments and results along the way.
You implied that presentation of V_PRESSURE pre-determines an expectation of S_BARO irrespective of whatever further S_? statement follows.
Is this understanding correct?
