S_GAS, send and request problem

[Marcin]

I register the S_GAS variable, then set Mymsg as V_VOLUME - I send the data to Domoticz as V_VOLUME. In domoticz I define the sensor as GAS so domoticz presents the data in m3. But when NOD sends a "request" to domoticz - domoticz does not send anything as a V_VOLUME or V_FLOW variable, but only V_VAR1 and it is a value in KWH instead of M3. Why is this happening? Domoticz version compiled on November 28, 2024 from sources. Mysensors 2.3.2. I'm trying to make a gas consumption sensor - which after restarting the node will first read the last value from Domoticz and then provide full readings - Domoticz does not accept incremental values ​​for S_GAS.
