Support for 433,92/868 Mhz La Crosse weather sensors

SimonTemplar

Hello Emile,

FYI, for the La Crosse weather sensors there is a lot of protocol information available.
It regards these 433,92 Mhz sensors:

• TX2
• TX3
• TX4
• WS7000 series

And these 868 Mhz (IT+) sensors:

• TX23 IT+
• TX29 IT+

Here is info regarding their wireless protocols:

Based on the flowchart in this topic;
https://forum.athom.nl/discussion/219/will-homey-support-device-x-read-this-first

433 and 866 is on the community

So its waiting untill someone creates an "app" that support these sensors.

But you made it much easier for the community by posting this information!

Thanks for that.

@PeterGroeneweg;
You're totally right!!

Maybe i will buy some of these sensor (cheaper then Z-wave) and multiple sensor around my house can give a more accurate (averaged) temperature then 1 or 2 expensive sensors like NetAtmo's.

And maybe my neighbors already have these sensor (cheap weather stations) that Homey can receive :Evil:

MarcoF,

I saw the flowchart but I don't know how to program and I assumed somebody is interested.

PS. An addition for La Crosse sensors:

• TX-6U
• TX-7U

The communication seems to be ok because the values of temperature and humidity are shown in the device after pairing. But there are problems in the flow, I was not able to trigger a flow on a change of a value or at reaching a value. If someone succeeded to make a working flow, plase post it here, or is it a bug?
