Dans les applications industrielles et tertiaires, il semblerait que le vénérable protocole Modbus fasse un retour en force. Je l'utilise souvent dans mes applications domotiques.

My ESP32 ModBus Adapter is successfully talking to my Kronoterm Heat Pump! It's pulling back some basic information, which is current being exposed via the Matter protocol. Took a few tweaks of Baud and Address, but it's working!

ESP32 ModBus Adapter + Solax X1

ESP32 ModBus Adapter + Solax X1
In this post, we're going to connect my ESP32 ModBus Adapter directly to my Solax X1 Inverter, so I can get real time data from it and expose it over Matter. In a previous post, I exposed my SolaX over Matter by using ModBus TCP and that worked really well. However, I wanted to continue developing my ESP ModBus Adapter. The first one I connected had been working away for several weeks without any issue.

The power flow arrows are wrong, but my ModBus adapter is working! It has successfully exposed my inverter over the Matter protocol. Sweet.

going to attempt to connect to my Kronoterm Adapt this weekend. I've got the ModBus Adapter all set up, so hopefully it's just a case of connecting wires....

I have improvised a connector for my Solax inverter. This will connect into the COM port and communicate using ModBus. The ESP32 firmware will then expose the inverters basic information using Matter! That’s the plan anyway.

The OT protocol problem is real — Modbus and DNP3 were never built with authentication in mind, so IDS has to infer intent from traffic patterns. Passive monitoring plus asset-aware baselining catches what signature-based tools miss in ICS.

Made up two more ModBus Adapters. One for my solar inverter, one for my heat pump. Hopefully I can test them over the weekend.

Gerade eine vollständige Dokumentation des Modbus-Interfaces meiner Wärmepumpe gefunden. Sobald die IT-Infrastruktur im Haus aufgebaut wird und ich ein bisschen Zeit zum Basteln habe, kann ich das Teil komplett lokal steuern und von der Cloud trennen 🤩

Hmmmm...
Ich habe so die Ahnung dass der Elektriker der PV-Anlage den Modbus-Zugang gesperrt hat um sich Folgeaufträge zu sichern.
Ich kann die Anlage nicht mit Last-Management steuern, wenn ich das E-Auto anstecke zieht es primär aus dem Akku der PV. Das ist selten dämlich.

I’ve spent 3/5 days doing modbus configuration and there’s still more to do. I want to be done already. Not helped by the fact that we have almost no documentation on how 1 family of meters was configured so it’s blind checking.
