Tempest weather station

[pnajar]

I have a Weatherflow Tempest weather station. On a day like today, when the skies are heavy with dark gray clouds, I'd like to use the illuminance sensor to trigger my evening lighting scene. Since I don't see a way to connect the Tempest to HE, and I do have an HA Green that is connected to the Tempest, is there a connection means to connect HA and HE so I can use the Tempest to trigger a Scene? If yes, how would I do that?

Search for Weatherflow lite. You can connect your tempest to HE. I use mine daily for rules.

Yes, use Home Assistant Device Bridge.

[RELEASE] Home Assistant Device Bridge (HADB)

All new version 2 now available! Features This version subscribes only to events you select from the list of entities within the Home Assistant Device Bridge app. The version 2.x driver no longer listens to all events, thus significantly reducing the CPU load on your Hubitat Elevation hub. After upgrading, you must open the app and press the Done button. IMPORTANT: The Home Assistant Device Bridge version 2.0 app is now mandatory. The version 2.0 driver will no longer operate as sta…

There is also @snell 's weatherflow driver that can easily trigger scenes.

You can also get creative and use the WeeWx as a data collection/dashboard for your Tempest and then use the MQTT option to publish observations that the Hubitat can use. The great thing about the WeeWx -> MQTT -> Hubitat solution is my preferred is because of the real time observations with no cloud needed vs. the polling used for their API in the cloud. I wrote my own driver for it and published it here. You will need another device like a Raspberry Pi, NAS, or something that is always running 24/7 to make this solution work.

WeeWx MQTT Listener Framework Driver

I was up late last night cleaning up local access to the MQTT driver of a WeeWx implementation that is hosting my WeatherFlow Tempest weather station. It's very basic, has some error handling to reconnect to MQTT if the connection is dropped. Also just for better understanding there are 3 json payload types that WeeWx puts on the weather/loop topic: 1 Minute Observations 3 Second wind and rain 5 Minute WeeWx archive observation To keep updates to a minimum I filter for the 1 minute observati…

Why try to reinvent the wheel?! Just use WeatherFlow Lite. It works great!

@TArman

Why try to reinvent the wheel?!

The advantage of using Home Assistant along with HADB, or using WeeWx as @ronv42 suggested is that these are not cloud dependent.

Why have a weather station in my backyard that is capable of providing data on the LAN, if I have to use a cloud integration to access it on Hubitat?

[TArman]

But, Pnajar already has a Tempest!

@TArman

Pnajar already has a Tempest!

Exactly. So using either HADB or WeeWx, he can access his data from his Tempest without any cloud dependence.

Using HADB would actually address @pnajar's question, quoted below:

@pnajar

I do have an HA Green that is connected to the Tempest, is there a connection means to connect HA and HE so I can use the Tempest to trigger a Scene?

For any one else interested, it is also possible to access Tempest data locally using Node-RED. I used to do this - just by creating a suitable UDP listener in Node-RED. If Hubitat permitted user drivers to bind a UDP port, we could have a fully local Tempest integration that didn't require HADB or WeeWx. Any chance this can happen, @gopher.ny?

[TArman]

Ok, whatever you say, but I’d do

And spend my time enjoying the evening.

I didn't dig into their docs much, but a quick look says:

The WeatherFlow Smart Weather Station's hub broadcasts UDP messages over port 50222 on the local network.

This should work as of platform 2.4.0. Has anyone tried and run into a specific problem?

I have not. Will tackle this later this week!
