G2 230ACX via openHAB/MQTT

[Thorhammer]

Hello Forum,
sorry if I have to write in English, because I donŽt speak french.

This is my setup:
Mower:230ACX
Modul:usr-wifi232-t

I can contol the mower via "Tweak Automower PC". Now i want to integrate the AM in my home automation system (openHAB/MQTT). So one of you has already realized that?

Thx in advance and best regards
Thor

Yes ! "Razmoket" did !

hi chercheur,

great, thanks for your fast replay. As far my translater works, thats what iŽm looking for ;-). But how did he do this? I am very familiar with openHAB and MQTT, but I have no idea how to get the AM communication with the MQTT.
He mentioned the he has developed an "tondeuse virtuelle" / "virtual mower". Like a openHAB Binding?
Sorry, iŽve so many questions.

best regards
Thor

Yep. We worked on this "together" and a generic "how to" document is on its way.
The project includes the creation of a WIFI module (ESP8266) in the mower. The data collection happens on that module as well as the MQTT connection.

[Thorhammer]

ok, very cool.
So youŽll then have a hardware and a software part. Is it possible to use the module (usr-wifi232-t) that i already have in the AM?

[chercheur]

No. The embedded module takes care of the MQTT postings.

[Razmoket]

In a nutshell: An embedded module in the AM takes care of all the messaging part to AM, using Husqvarna proprietary protocol . The module communicates to a local MQTT server on a pi. OpenHAB binds items to MQTT topics, and presents info + links it to external services (push notifications, meteo, ...)

To implement it you need an ESP8266 module, an attiny85 and some basic soldering skills + a raspberry pi

The virtual mower is something else: a small module which emulates the serial communication of an AM, to allow me to test communication on my desk, without the mower (lack of space) and only install the module in the AM when the solution is debugged

Hello Razmoket,

this sound very good.
OK what iŽve is: ESP8266 module, soldering skills, Raspberry pi3 with MQTT, openHAB and some other stuff on the PI.
pls correct me if iŽm wrong. So you hand out an howto (solder the Module(also what to buy, recommendation), implement MQTT communication and so on) right?

best regards
Thor

[Razmoket]

Hello

"How to" is mostly related to the configuration of Raspberry and implementation in local network. Which you already did.
And for ESP8266, as you already have one, you should be able to flash an hex in.

So...let's discuss in MP for special instruction for you.

Hello Razmoket,

thank you very much for the kind support.

best regards
Thor

Too bad you choose to continue the discussion privately. It would have been instructive as I might try this kind of things in some time.

Hello Guiohm

Discussion is open on "realisation des améliorations" section.
