I like to share my Integration of my Gateway for the Hoval Belaria heatpump. I made a integration with modus over tcp with this configuration:

Hi

can I ask you how did you get the modbus connected with the hoval Bellaria?

I have the same heat pump but I don’t find any indication that there is a rs485 connector

Hi @christiankropf

I have a Belaria SR11|4 heat pump and would like to connect it to modbus. Could you maybe share how you did it in your case?

Thanks a lot and Kind Regards,
Marc

4

I have a Hoval Belaria Pro heatpump as well and would like to integrate it in Home Assistant. I am an amateur and new here. Could you be more specific, how you did this? Did you include all of the lines in the configuration.yaml ? How did you get all the monitors on your screen.Thanks for your help.
Anne

Hello

I use the HovalConnect Modbus Module:

HovalConnect Modbus | Hoval Schweiz

I am using the HovalConnect Modbus Module:

HovalConnect Modbus | Hoval Schweiz

You need a HovalConnect Modbus Module. In the first line you have to configure the modus target IP and port. Under sensors you have to add all datapoints you like to read over modbus. I use apexcharts-card HACS Integration to visualise the data.

8

Hi @christiankropf Have you been able to set the hot water temperature using modbus? Setting the heating target works fine for me, I can also change the hot water program, but not the target temperature…

BTW: I was able to get the COP and the energy consumption of my Hoval Ultrasource Heatpump using this configuration

I finally got my modbus module for the hoval Belaria Pro last week. I can read the sensors with your yaml code. Would you kindly share the code for the card with the diagrams /displays of the differend sensors? Thanks in advance, Anne (annreal At gmx.de)

10

There is a cheaper (and for me much better even if it is not for free as I would prefer) solution for my Belaria than original Hoval Gateway: https://github.com/wladwnt/CAN-Gateway

11

Maybe cheaper but not less complicated :slight_smile:

12

Here a example:

Hey mightea, in the TTE-GW-Modbus-datapoints sheet you can see if the parameter is wirtable or not. The datapoint 1499 is not wirtable over modbus. Maybe you can set i over the datapoint 1497 “Normal-Warmwassertemperatur”.

And thank you for your config, works like a charm :slight_smile:

Thanks @christiankropf I tried that with no success. My plan is now to change Hot Water temps using a different program set on the unit itself as toggling between programs is working… If you find a better solution let me know!
