Python Plugin: PWS (Personal Weather Station)

[Aroby]

Thanks Xorfor, somehow I didn't found https://github.com/Xorfor/Domoticz-PWS-Plugin/issues/8.
Awesome! The Garni 2055 Arcus is sending it's data to Domoticz now with the iptables rule in between.

Very nice plugin!

Hi all,

I've a question about installing this nice PWS plugin for my Ventus W830 ver 1.1.4. I've made a DNS record for wow.metoffice.gov.uk pointed to my domoticz server. (I cannont use Wunderground becase this is in use). The data is actualy into domoticz according to the log:

Can this error in de plugin.py be corected in the next version?

Kind regards

@atlantica: should be fixed in the current version

[atlantica]

@Xorfor Thanks for the quick response and fix!

It's working now only that there are still errors in the log:

@atlantic: I made a quick fix. Hopefully this prevents the errors in your log.

The data is importing now; only 3 records are still empty:

For all Ventus W830 user with version 1.1.4 (First version) is working when youy add the following DNS record in your Router/DNS server:

• wow.metoffice.gov.uk pointed to my domoticz server.

and add the following nat route to your dmoticz server:

• Linux (Raspberry PI, etc)
  iptables -t nat -A PREROUTING -s [IP of PWS] -p tcp --dport 80 -j DNAT --to-destination [IP of Domoticz]:5000
  Windows
  netsh interface portproxy add v4tov4 connectaddress=[IP of PWS] connectport=80 listenaddress=[IP of Domoticz] listenport=5000 NOT TESTED YET!!!

Hi, is it possible to modify this plugin to work with ObserverIP software ?
That units run a web service which can be read locally. I can produce screendumps if neccesary.
I run a dzevents custom made script that does the job, but it might be usefull to add this to this plugin.

That is correct that these sensors are still empty: according to your log, your pws is not sending this data!!!

Can you send me more information? Something like the json(?) message from your PWS. your dzevents script, etc!
If it is possible to fit this in the plugin, do you want to test this?

Of course I will, but, I will probably do that tomorrow. Testing is no problem either.
The ObserverIP unit is NOT producing json. It produces a web page which can be read with a http get ...
like this, (I can supply a html dump of the page ...)

Please send me the information by pm.
And yes, a html dump, url, etc will help.

Thanks for that understandig. In that case i have to use the wundergroud..... And I can confirm that is working then

Is it possible make an option to forward the incoming request from the weatherstation to the url from wundergorund in your pluging? All the correct data for wunderround is already in there....

Hi

If I will use this plugin, will Domoticz update my devices every 60 seconds?
I understand Wunderground will only update every 10 minutes or longer, as there is a limit for downloads (500) a day.

My old weatherstation (433mhz) updated every 16 seconds the devices in Domoticz.

Hope someone can explain this to me. As I will use the windsensor for screens, so when the windspeed increases I can't wait for 10 minutes to have 'actual' readings

I stopped using this plugin and went to wudirect ...
Because sensors are only updated by this plugin when they change it is a little bit difficult to see but in my setup sensors are updated a lot faster. I see wind every 30 seconds...

The update interval is specified by the setting in WS View. There is a parameter 'Upload Interval' with a default of 60 seconds. If you want, you can change this value.
The data is pushed to the plugin, so by default each 60 sec. the data will be changed in Domoticz.
If you want to have the data updated every 10 seconds, please change the parameter in WS View in 10!

Check if python and more important if all necessary module are installed for using python plugins. See wiki page https://www.domoticz.com/wiki/Using_Python_plugins

Thanks for your quick reaction. I will check and read the wiki!

[bas1502]

Thanks it works, now I can find 'PWS'.

After I added new hardware (PWS), my Domoticz environment isn't stable any more. The language turns into Albanian and I get the message 'Problem saving settings!' when I try to change the settings.

I don't know how to solve. Search the internet but no solution.

Thanks for helping me.
