@gimespam Did you get it working with an ESP32 to MQTT ? Would love to try it out if you have something. :)

Ok, I mailed the heat-pump guys in China, and it turns out we used the wrong port on the mainboard. It has a dedicated port where the device is simply a slave. So now I can use modbus poll software for example and see and change everything. Turn the pump on or off and so on. The connection we...

Again some progress, the modbus slave software works with you settings, I can see data on the 2011 to 2080 registers. But that is on slave id 3. So before setting it to 2 ( instead of the WiFi module ) I wanted to be sure what the other register data I need to put in the slave software. So I...

@jschulze No luck with MQTT so far... :( Still trying to get something with modbus now. I can't get any data in modbus slave, I can see in the Communication window there is dat flowing. But can't get is to show... Also tried pyModSlave. Same result. So now only data in Simply Modbus slave...

They have 2 version's of the WiFi module, old V1 and new V2. The Home Assistant scripts is for the new V2 version, and ofcourse we have the V1 version. :( We are now testing the MQTT from the V1 it is usable.

Again some progress, reading the holding registers worked, take a few times to read, as it fails the crc. I think because of the broadcast messages, but pressing read a few time works. Register 1011 is now 0, if I turn on the heater from the display this turns to 1. Also the setpoint value...

@jschulze I am going to try some things tomorrow. And I have found that WireShark also can make more sense of the raw data with a modbus plugin. Maybe handy for more investigation work. @mrwee I have attached my config file, you can import directly in Simply Modbus Slave. Don't forget to...

My bad, thought you wanted the raw data. Here it is in Modbus format.

Oops, of course. Here it is.

Here is log from IONinja. Only the display and the RS485 interface connected, and turned the heater off and on with the display. So that data should be in the stream.... Tomorrow I can make some more log's if needed.

I have bought a license for Simply Modbus Slave, to much stop and go indeed... And yes, the value's are correct from the 2011 range and up. Still looking on how to send command's. They are in the 1011 register and up. As in the PDF document. But I have no idea how to do that, maybe our great...

Whooohoooo Finally some data.. :) :) I did not test your suggestion on first register 2001. And I needed to set the option "respond to all slave id's". Is there a way to find out what the correct slave ID is? Other then testing number for number... ;) Any idea on how to get this modbus...

I have tried it today with Modbus Slave. But I think I am doing something wrong with the settings, as I don't see value's in the data screen. I have uploaded screenshots of the Modbus Slave program. Any pointers would be appreciated.. :)

@jschulze Going to try that here also with my machine, thnx. Hopefully today or tomorrow when the parts are in. :)

@mrwee Thnx for the update. I am waiting on a few parts that should arrive tomorrow. Then I can further test. :) I will keep you updated.
