Wind Direction condition always false

[johnnyt]

I have a program that checks for wind direction >=0, which should always be true but is always false.

Attached is screenshot of the program showing it's evaluated "false", screenshots of ISY GUI and NS Node value for wind direction.

I downloaded the log (attached) but it had no data (at warning level) going back 3 days or so, which seems strange. so I changed level to "debug" and restarted NS, and attached that second log after letting things run for a minute or two.

for the record, I right click and select "Run If" to force the condition check. It does the same thing enabled and disabled.

This is what I see in the Event Viewer.  It looks like the IoP isn't handling the comparison of UOM for wind direction properly. 

@Michel Kohanim, @Chris Jahn

The WINDDIR status value is set to UOM 76 (wind direction degrees) but it seems to be comparing against UOM 14 (degrees) and failing.  My program is simply doing "if winddir >= 1".  Just like @johnnyt's program above.
 

[johnnyt]

Just caught a "West" report for wind direction that when back to degree on next update.

 

and the variable I try to set refuses to change (stays at 0)

 

[johnnyt]

I caught the following in the event viewer:

Hi, I opened a support ticket for this and just got this response back:

This is a problem with the node server, it should not be using UOM 14 in (generic temperature degree) in the node definition, instead it should be using UOM 76 (wind direction 1-360 deg, 0 means no wind).

The ISY attempts to convert compatible UOM's but temperature and wind direction are obviously not compatible.

Fixed in version 3.0.24 of the node server

ok, thanks. not seeing 3.0.24 in the node server store. Tried closing and reopening browser still only see:

Use the Refresh Store button to refresh the store listing.  Otherwise, it auto updates the list every 8 hours.

There was a message this morning about the new version and that I needed to restart. I did so and am now at the latest version and see that the wind direction is now working. Thanks.

[johnnyt]

I'm seeing the following message in event viewer:

Mon 09/26/2022 04:22:07 PM : [ n006_207296]  WINDDIR 267 (uom=76 prec=0)
Mon 09/26/2022 04:22:07 PM : [D2D*CMP 036F] STS [n006_207296] WINDDIR B Cannot convert values (from=0E to=4C)

There is data in the GUI and it matches what the tempest shows so I'm not sure what the second message is all about.

 

[bpwwer]

Maybe a program is trying to compare winddir with something it can't convert wind direction into.

[johnnyt]

The only thing I do with wind direction is a program is store it in a state variable, i.e.

If
        'HVAC / Climate / WeatherFlow / ST-00061544' Wind Direction >= -1°
 
Then
        $sWeatherStation.WindDirection  = 'HVAC / Climate / WeatherFlow / ST-00061544' Wind Direction °
 
Else
        $sWeatherStation.WindDirection  = -1
 

That said, I see it isn't working. My state variable is '0' - the init value - and it hasn't changed since last reboot.

Could it be because it tries to store the "degree" character too?

[bpwwer]

I think it complaining that wind direction can't be compared with -1° so it does nothing.

Ok I changed the code and the error doesn't come up anymore, however the variable does not get set when it should.

Here's the new program logic (0 is converted to "No Wind")

If
        'HVAC / Climate / WeatherFlow / ST-00061544' Wind Direction > No Wind
 
Then
        $sWeatherStation.WindDirection  = 'HVAC / Climate / WeatherFlow / ST-00061544' Wind Direction °
 
Else
        $sWeatherStation.WindDirection  = 0

 

It evaluates True 

 

But the variable has not changed value since last reboot, when if was initialized to 0

 

 

Here's a sampling of WINDDIR values over the past few hours  - none are 0

Is your weather flow set to measure the wind every 3 or 15 seconds?

Try removing the else clause and see if the value is going back to 0 between actual samples.

where do I see / change that? I looked through the settings but didn't find one for this. It looks like it's every 3 seconds just from watching changes.

Ok I did that and ran it (if) which ran true and stayed true with no change to the variable. I think if this had been the issue, the timestamp for the variable would not still be the time from the last reboot 8 days ago. 

[hart2hart]

Does running Then record a value?

The every 15  seconds is a battery saver feature.  Its under settings stations stations "your station name" Manage Devices Sky Advanced Power Save Mode turn it on.

 

You may have temptest where sky and air are in one device together so it may be a little different

In iOs app...

You set this value in the node server configuration page.  In the Custom Configuration Parameters section, set Rapid Wind to true or false.

FWIW, I wrote a program identical to yours quoted above, and the variable updates as expected.  Maybe there's something specific with your installation of the node server.

No, running then is no different than runnin if.

I have an all in one unit and looked again. don't see any option to change anything related to frequency of wind reports. I do know if the battery goes low, it will reduce itself to conserve energy from 3 secs to 6 secs to 1 min to 5 mins. https://help.weatherflow.com/hc/en-us/articles/360048877194-Solar-Power-Rechargeable-Battery

The NS config 'Rapid Wind' option is/has been false. I set to true and restarted NS. The wind reports certainly accelerated as seen in NS log updates but the variable doesn't change either automatically or when I 'run then' using this config. 

[johnnyt]

So I created a new program from scratch (no copying) to do the same thing and it works fine. There's actually a visible discrepancy between the old and the new "action" statement

Here's the original action:

        $sWeatherStation.WindDirection  = 'HVAC / Climate / WeatherFlow / ST-00061544' Wind Direction °

 

And here's the action for the new program: Check out the difference in last character.

        $sWeatherStation.WindDirection  = 'HVAC / Climate / WeatherFlow / ST-00061544' Wind Direction 
 
So then I created a copy of the original program and it had the extra character too but when I changed the equation to a different data element and back again, the extra character was no longer there.

 

Guessing this is a 1 in a million occurrence so won't both opening a ticket with UDI support but next time I have difficult to reconcile program logic I'll definitely look for this issue.

 

[johnnyt]

I should add that I originally had the units (in Tempest) as "cardinal", e.g. NW, W, etc. and changed them to degrees without actually changing the action statement so maybe that's what caused this.
