Davis Vantage driver : stormRain and stormStart

[Jacques Terrettaz]

Hello,

I am trying to obtain the stormRain and stormStart values  sent by the Davis Vantage.

The tag $current.stormRain seems to work ( there is no rain episode right now but the value returned is 0.0), but the tag $current.stormStart returns "?'stormStart'?".

Thanks for your help

Hi,

The Vantage driver certainly decodes stormDate. I suspect you might find that unless there is stormRain there is no stormDate. Might be worth checking again when you have rain.

The problem is that the unit system is unaware of stormStart, so the tag $current.stormStart gets returned as a raw value, instead of a ValueHelper. I've created issue #380 to track.

This is an easy one to fix, should some noob want to take it on!

I certainly am a noob.  Just ask Gary.

 

Based on the “hint” from Tom I added stormStart to units.py and it seems to work.   I probably missed the boat somewhere.

 

obs_group_dict = ListOfDicts({"altitude"           : "group_altitude",

                              "cloudbase"          : "group_altitude",

                              "cooldeg"            : "group_degree_day",

.

.

.

"stormStart"         : "group_time",

 

 

This is what I get:

Storm Rain

It is true that it make no sense to expect a stormStart value when stormRain = 0 !

I have anyway added « StormStart » in the obs_group_dict of units.py, and I will wait for the next rain period.

Thanks

Jacques
