Weather Station Data

monaco · April 29, 2020, 10:02am

Can I send data from my weather sensors in HomeAssistant as PWS data to Weather underground?

MarkR · May 5, 2020, 9:09am

Cumulus can now export to MQTT for any weather station sensors, so if you have a fine offset, Davis, Ecowitt etc, you only need to use Cumulus.

What is the input to Cumulus, USB port ?

MarkR · May 5, 2020, 9:49pm

yes or ip depending on the weather station… my Davis was usb and the ecowitt is via ip address on local lan

mr.sneezy · May 6, 2020, 11:17am

Cool, can I run Cumulus on the same RPi as HA ?

MarkR · May 6, 2020, 12:52pm

I don’t see why not. I used to but now have them running on different devices.

I am using openhab with the ip observer units, works well with no cloud and local scrapping at. 12 second intervals.

Info on how it is done is found here and you can keep your ambient weather screens and add on the ip observer for around $50 if your weather station does not have one.

Would love to see HA support this method.

mr.sneezy · May 7, 2020, 8:02am

Is the IP Observer an IP gateway ?
If so does it use the Ecowitt IP packets ?

The reason I ask is the late firmware for a lot of Ecowitt (AKA Fine Offset) WiFi stations now support a custom server upload using their Ecowitt protocol (as well as WU, WeatherCloud etc).
If the IP Observer hardware uses it then by default a lot of WiFi stations might also work with that method above…

Skinah · May 7, 2020, 9:27am

No idea what those packets are. The ip observer works by displaying a summery of all the data on a HTML page that can be fetched and scraped for the data. A simple GET request and you have all the data locally with no cloud and updated every 12 seconds. I don’t
Know of any other weather station that is in the same price range and can do that at the same time it uploads to weather underground.

mr.sneezy · May 7, 2020, 9:57am

OK Thanks.

Something I had in mind as possible also is use a NodeMCU or ESP32 module to accept the Ecowitt packets and convert to MQTT for HA (if not via the native ESPhome API). Those modules cost as little as $4.
Unfortunately while I can see the chain of hardware/code required, it’s too big a knowledge stretch for me to create that code myself. If we go into lock-down again here I might have the time to learn…

@kslb
it is possible aquire by mqtt soilmosture sensor?
I have Ecowill WH51 sensor

kslb · May 11, 2020, 6:58am

Sorry, don’t know that - this is question for weeWX community…

mycrouch · May 17, 2020, 6:50am

I was looking to add the data from my weather startion directly to the DB in HA. Found the homeassistant_ecowitt intergration in Community HACS. If you’ve got the WS View app you can configure the connection in the Customized Server tab to point the data at your HA IP and chosen port.

Hey guys,
my weewx wont’s start, any ideas why?

Weewx config file problem…

Try to update weewx platform and go line by line in configuration…

Also it seems that you do not have installed all used add-ons in weewx. Where do you run weewx?

joem · June 25, 2020, 6:12am

It happened after an apt upgrade. I think something broke during the install, might be some python incompatibility.
Running it on a raspberry pi 3.

joem · July 1, 2020, 11:15am

Solved uninstalling and cleaning up everything related to python3.

Question, is there a way to use our own wx station data to populate the weather card? It would be awesome to have such an option.

Looks like you are using the old format for Mqtt sensors.

They should be similar to the below:

mqtt:
    sensor:
        - name:
