rtgd-0.5.5 extension Wind Direction Average

[David Marshall]

Built a new station using an esp32 which mqtt’s data every second to a Raspi. A python program converts this to a txt file which I then file parse into weewx. All ok.

I have successfully installed the steelseries gauges and the rtgd extension. All works fine and it is fantastic to see the gauges updating in real time.

Just one small problem - the Wind Direction gauge shows latest and average, but the average is always the same as the latest. Tried playing with the rtgd.py program but even when I set data[avgdirection] to a different value, nothing  changes.

Any ideas?

Use the MQTT driver which takes the data directly from your mosquitto server.

Avoids all the middleware.

I use Rich's excellent package.

Thanks for spotting this. There is an issue is v0.5.5 that maps current wind direction to both the 'bearing' and 'avgbearing' fields used by the SteelSeries gauges. I should have a fix by tomorrow.

Thanks Gary, looking at that.

Tried to keep things as simple as possible at the esp32 end, (which by the way is an amazing piece of kit for $10). So it is sending very raw data - number of clicks from the rain bucket, number of revolutions from the wind cups, for example. The python program then converts this into sensible data.

If I need to make any changes in the esp32 it needs to be physically connected to the pc using the Arduino ide, which is a pain. Also wanted to make as few demands on it as possible until I see how stable it is. But so far so good.

If it stays stable will try the direct mqtt driver.

Thanks Gary, that would be great.

Amazing piece of work by the way.

I've released v0.6.0 which should fix the average bearing/current bearing issue highlighted in this thread. The release can be found in the usual place.

In testing v0.6.0 I've noticed a problem with sporadic windrun updates on the Wind Rose gauge. I'm not sure if this a bug or an issue with my system as it needs more debug time than I have available just now. I will investigate later this week and if necessary make a dot dot release.
