No Data from Heatpump

[sonny1985]

Hello :)

I got my Heishamon today.Arrived very Fast

Plugged it in on the CN-NMODE Plug into the Heatpump (another Connector like CN-CNT i dont have) using the cable that comes with heishamon, i ordered a 2 m long one with it- easier to install :)

My Heatpump Model is a WH-SDF09C3E8 (Outdoor: WH-UD09CE8)

Setup with Wifi worked fine, included it also in the MQTT (iobroker). Assigned to my Wifi-Connection at home (My own SSID) also worked good :)

on the HEATPUMP Section at the Web Interface- i dont get any Values shown from my Heatpump... -> Wifi signal: 76% Memory free: 67% Correct received data: 0% MQTT reconnects: 1 Uptime: 0 days 0 hours 13 minutes 41 seconds

In the CONSOLE Section i find always:

Received 0 bytes Data Previous Read Data attempt failed (Timeout)

... This "Received Bad Header" comes only... until it starts to request Data from the Heatpump again ....

It looks like that my Heatpump dont answer to a Request ... A little bit of Help would be appreciated :) Sorry for bad English, im from Austria :) Many Greetings

Sounds like old generation F (also lack of CN-CNT point for it). This project is for newer gen.H , work for J as well,but for sure not compatibile with F and earliers...

Hi. Attachment i did 2 Photos of the Heatpump PCB .... Looks like i have the same Problem as Here: https://github.com/Egyras/HeishaMon/issues/229

That means no luck for me ? :( , Is there really no Option to make this Heatpump external Controlable (IoBroker)

Everything is possible.. but you will need to find protocol to communicate.. after know protocol it could be possible to integrate it. Heishamon started from H series of heatpump, fortunately newer models came with compatible protocol..

If Panasonic mark heatumps consistently this is generation C !
I hear about F , i hear about D ( from 2010 ) , but C with is new ,is very strange . What build year is this HP ? Is it brand new ?

[sonny1985]

Hi. I build my House 2015. There I let this heatpump beeing installed. Panasonic confirmed me today that it is a C Modell. It was produced 2014.

The fun fact is, that all the values, heishamon is able to handle, I have them in my pump, think they never change something there. What is not available is all about cooling, and this "zones" in heating. Cooling was an option for it, but I declined it.

It looks like my heatpump speaks another language, I will ask my dealer who installed it 2015 if I can put the original internet cloud thing in it, but connect it to cn. Nmode instead of cn. Cnt or probably he has another idea. Maybe it's possible to exchange the whole system board, so I can search for a used one. Of the H model. But I think it's not possible... Problems communicate with the outdoor device then...

@sonny1985 i think for you would be best way to start from this project: https://github.com/v-s-c-o-p-e/geisha_aquarea_panasonic_arduino_esp8266_proxy

it's not updated for while.. but maybe you will find something usefull. Also you have allready have hardware you need :)

[sonny1985]

Hm Okay thanks so far. I will end up , to buy the original Panasonic Heat Pump Manager (PAW-hpm2) in my case. It supports all old heat pumps (Be aware 3 different cables). It get connected to CN_REMOTE instead of the original Operating Panel.Integrated as COMMUNICATION DEVICE to the Heatpump

In the Iobroker i would read all Values with the "Parser" adapter from the Web Interface. And update the Datapoints (Objects). So i can monitore it in Grafana.

Operating / Sending Commands is Possible with HTTP Commands. It has alot of advantages: I can control it beyond the original control logic (When i send a Start heating command) it STARTS a heating cycle - without taking care when she did that a specific time ago (Internal logic)

Sounds like a good Solution for Older Heatpumps. My Model is listet there too, i found all older Models so far, ... Mostly them without a CN-CNT Connector :)

[geduxas]

@sonny1985 also you could monitor all protocol and share your finding.. maybe someone could add it later to heishamon.

@sonny1985 Did you make any progress on the generation F connection. Do you use/have the HPM connected? How you communicate with IOBroker and what cable do you use for the HPM to connect to F generation via CN-REMOTE2?

[sonny1985]

Hi. Sorry for late Response, i cant realize this Project with the Pump-Manager, The Pump Manager you get ... The Problem is the Cable i needed- it was called PAW-HPMINT-U (in MY CASE)

You should need a PAW-HPMINT-F or M (The difference is the lenght), the one i need , U , is totally different, there is a circuit built in ....

To get the Data to IoBroker i planned to realise with the Parser Adapter (Read it directly from the webinterface of the HPM)- Should work.

No chance to get it online anywhere. After Panasonic told me: Unavailable anymore- i put this project to side :) Greetings

As long as my heatpump works, i dont change it to a newer model.
