Domoticz

I have written a Python plugin, to capture data directly from my weather station. So no need to upload the data first to WeatherUnderground, Ecowitt, WeatherCloud, WOW, etc.
The README describes the use of WS View to connect your weather station to your router and upload data to Domoticz.

https://github.com/Xorfor/Domoticz-PWS-Plugin

In general, if the station is supplied with 'EasyWeather' software, it is likely that the station will work with this Domoticz plugin!

Please tell me your experience, which weather station you are using, which tool (WS Tool, WS View) you used, etc.

Final version is available, with some extra devices.

Added some improvements for the Rain sensor.

Added extra device for wind direction.
Extra documentation to link your PWS to Domoticz.

Some code cleanup (Black formatting) and more documentation https://github.com/Xorfor/Domoticz-PWS- ... /README.md

I removed the extra checks on WeatherUnground and Ecowitt protocols. And added extra documentation about EasyWeatherV1.4.5 which is available now for weatherstations.

New version available and also tested on the latest EasyWeather version.

Fixed: Sometimes the total precipitation from a day was added to the next day, because of different times settings on the PWS and Domoticz server.

I'm using a Alecto WS-5500 weather station and WSView software to setup the device and its work very well, today i updated to the latest release because i encountered the rain gauge issue. A few minutes ago at 00:00h the rain value of the previous day is still copied to the next day I will see tomorrow if the problem still exists.

I have seen the same problem. Also with my latest fix. It is difficult to debug this. Now I am not sure if it is a bug in my plugin or in Domoticz.

Using Alecto WS-5500 software version 1.4.4 working great, selected for now Ecowitt protocol.
Thanks Xorfor all the work.
Do you know what the difference is between Ecowitt and Weather Underground protocol only the "Dew point"?

Also WindChill is not reported in the Ecowitt protocol

The issue still exists. 1 minute after midnight the total rainfall of the previous day is visible

I didn't have this problem this time. In my log I saw that the correct data was send and the sensor showed this data.

I am running an other test, and it seems that updating the Rain sensor does not work as expected! At this moment I have a plugin with a rain sensor and I send 1.5 as total precipitation, but the sensor still displays 0.0!!! I will do some more investigation...

Maybe this can help you, on 23:59 hour the last update is written to the graph, on 00:00 hour the value of the day total resets to 0mm. After 1 minute the total previous day total becomes negative and will be displayed as a positive value in the day graph. (Donderdag) see database.

After viewing the log there is 1 hour difference in time visible, is this possibly causing the double count?

No that is not the problem, just a debug line added by me. Later on in the code, this utc time is converted to the local (time on the Domoticz) time, to be sure that the PWS is sending data for the correct date.

Meanwhile, I have found 2 problems in Domoticz with this rain counter. These problems are NOT related to python plugins, but can also be seen in other hardware like Buienradar!!!

1. You will see that almost every day, the first hour has no data (also no 0 mm). As you can see in your table of data, that Domoticz (so not the plugin) stores the data every 5 minutes (sometimes 1 second later). At the beginning of a new day Domoticz resets its own internal counter to 0. If the PWS sends in the first hour its total precipitation, this value is stored at dd-mm-yyyy 01:00:00, not at dd-mm-yyyy 00:59:59. The graph should not show 00:00, or store the total rain fall at hh:59:59.
2. Sometimes the 00:00 shows the value 0, but then you will see a negative value at 01:00. For the day total this is used as positive value for the new day. See image as an example. I can not fix this. Hopefully the Domoticz programmers can do some more investigation.

I think I found a workaround for the problem in the Domoticz Rain device. I also addded a new Rain rate device.

tested the latest version for two days and now displays the correct amount of rain.

The script worked for the evening, but the next day this error appeared:

What is going wrong here? Thanks

try once to completely reset domoticz, i have had this if you only restart the service.
