RainMachine API for weewx- Driver Wanted/Needed

[G Hammer]

I have a RainMachine sprinkler system that currently uses NWS and WU info in determining when and how much to water.

They have recently added the ability to push weewx data to the system via a new API.

"Local Weather Push is actually an API call in RainMachine that lets you send weather data to RainMachine directly. This can be used with various integrations like WeeWX or CumulusMX"

Send POST to /api/4/parser/data with a JSON body as below. If
timestamp is missing the current device time when the POST was made will be
used.

{

  "weather": [    

    {

      "timestamp": 1563362587,

      "mintemp": null,

      "maxtemp": null,

      "temperature": null,

      "wind": null,

      "solarrad": null,

      "qpf": null,

      "rain": null,

      "minrh": null,

      "maxrh": null,

      "condition": 26,

      "pressure": null,

      "dewpoint": null

    }

  ]

}

The API is documented here: https://rainmachine.docs.apiary.io/#reference/weather-services/parserdata/post

Anyone up to creating a skin/report method for this?

[Antonis Katsonis]

What is the qpf, minrh and maxrh?

[G Hammer]

QPF- Quantitative Precipitation Forecast NOAA QPF Page

minrh & maxrh- Min/Max relative humidity.

Hi,

Please see this: https://github.com/weewx/weewx/wiki/RainMachine

There should also be a RainMachine beta firmware out soon but it should work with current beta firmware.

We would be greatly interested in your feedback.

Thanks,

Nicu Pavel

Hello,

I fail to get a token:

gary@ftp ~ $ curl -X POST -k -d ' { "pwd": "admin", "remember":1}' https://10.10.100.120:8080/api/4/auth/login

Are you sure your password is 'admin' ? 

[G Hammer]

Of course not <g>

I'm good to go now. Just removing admin as your message came in.

Forgot to add: you will need to go to web ui > Weather > Weather Sources > Developers and enable Local Weather Push parser.

Thanks,

Done.

Have a token, installed the extension, enabled push on the Mini-8, restarted weewx.

Getting an error:

It might be better to wait for the next beta, not sure atm why wouldn't it work without more logging.

 

BTW- the file, when downloaded is named 'rainmachine-weewx-weewx-rainmachine-v0.2.tar.gz'

Will fix, thanks.

[G Hammer]

I'm game to get any data needed for you.

I can enable addtional logging from weewx if you'd like.

This last message is ok, means that no data was pushed to the machine in the interval.

Can you tell me what weewx version are you using ? (weewx -v). I'm using the latest from git (3.9.0a1) and works fine.

The issue comes from the fact that RainMachine local network https uses a self-signed certificate. I could work around the verification in the extension code but not sure I should do that as seems that weewx might handle that already.

What I'm going to do is to add an optional no ssl mode that should work.

Thanks,

Nicu

I also posted a new version (0.3) which has a new parameter (default usessl = false). If you have https issues set usessl to false to use plain http communication.

Thanks,

[G Hammer]

I am running the current release version of weewx 3.8.2

I installed 0.3 and it works from the weewx side.

Oct  4 09:00:59 ftp weewx[26437]: restx: RainMachine: Published record 2018-10-04 09:00:00 EDT (1538658000)

Mini-8 received it.

2018-10-04 09:00:59,363 - INFO  - rmHTTPResourceApi4Parser:415 - Local Weather API push: 1538658000.0: {'maxtemp': 16.485185185185188, 'temperature': 16.041666666666669, 'dewpoint': 15.705232150809789, 'maxrh': 97.875, 'rain': 0.0, 'pressure': 10199.801134355374, 'timestamp': 1538658000.0, 'mintemp': 13.777777777777776, 'et': 0.0030527243389449561, 'wind': 0.24587199993115592}

The status on the Mini-8 shows No new weather data pushed.

In the weewx logs, I only saw the first report. After that first one, no entry for RainMachine at the next 3 report periods.

I'll check the Mini-8 after the top of the hour and see if it has different status.

[G Hammer]

At the top of the hour, weewx reported.

Oct  4 10:00:59 ftp weewx[26437]: restx: RainMachine: Published record 2018-10-04 10:00:00 EDT (1538661600)

Still the status says no push data.

A restart of the Mini-8 shows this in the log:

[G Hammer]

The Mini-8 is receiving and using the push data.

Seems it wanted to go past midnight to show proper status on the Mini-8.

In any event, all seems to be working well. No further Warnings in the Mini-8 logs and the 3 weather sources I have enabled all show a green Success on the dashboard.

Great, keep me posted if the data is correct at the right date/time.

Hi,

I decided to give this a try, and I've noticed what appears to be an strange data in the pressure values that this parser is reporting:

Enter code here...

2018-10-19 06:25:27,518 - INFO  - rmHTTPResourceApi4Parser:415 - Local Weather API push: 1539955500.0: {'maxtemp': 19.302000000000007, 'temperature': 2.911999999999999, 'dewpoint': -5.9699246296052841, 'maxrh': 52.0, 'rain': 0.0, 'pressure': 10297.794188428035, 'timestamp': 1539955500.0, 'mintemp': 2.911999999999999, 'et':

The value of:10297.794188428035

seems significantly out of line with the data received from other parsers (see screenshot).

I updated the extension to version 0.4 which should fix pressure conversion.

https://github.com/weewx/weewx/wiki/RainMachine

The time is always reported as 00:00 on whatever day for each local entry.

If you want to report the pressure in kPa, then all is well at my location using 0.4

Yes, fixed.

I updated the extension to version 0.4 which should fix pressure conversion.

When I saw kPa, I assumed it was an error; it seems that pressure, when
SI units are used, is normally reported in hPa instead (which is the
same as millibars).

But, I see a pressure value that is sensible as kPa, so obviously this
is right.

I am curious if kPa is in common use, or if there are just a small
number of internet aggregation sites that use it.
