Did it work out? I have a LG therma hm163m u33. What is your final config?
The working yaml for u33,flow l/m dont work for me

I am looking for the modbus code responsible for controlling (turning on/off) the circulation pump for DHW, which is it? I have therma v monoblock 9kW u44.
So since we know
- inlet temperature
- outlet temperature
- current energy consumption
how can we calculate current COP?
You also need flow.
Flow(m3/h) * Delta T * 981 (sm water) * 4.2 (sh water)
Answer is in Joule devide bij 3600 for kWh.
Now you can devide the outgoing energie by incomming energie = COP
Hello everyone,
Does anyone have LG hm161m u32? I am trying to use the waveshare RS485 to WiFi and PoE with no luck
must enable dipswitch for modbus and on controler must be modbus addres 1
on first look you have older non wifi / non modbus / older style remote so you cant updated
Yes, I have the U32,
the control is this one (without the CH01 error
)
And I am using the bellow LG IP485 Interface in order to get modbus A and B

Where I am sending the AB to the bellow waveshare 485 to WiFi POE
There is one PCB in the heat pump (the inverter pcb) where the IP485 LG interface is connected and flashing normally but I cant make waveshare converter to work with home assistant.
if you use china zlvircom you have same dev ip and dest ip and work mode tcp server? sometime you must go in waveshare web interface and than in zlvircom. In HA must add yaml with same IP to work
I have the same device.
Did you find a solution?
Hi Slawek,
I am in the same situation. Were you able to get a modbus map? I have the same shifted addresses (compared to the manual). My heat pump Hydrosplit R32 16kW IWT 200L HN1616Y+HU163MRB
