No serial communication from heatpump #2

Closed myfirstdatalogger closed 4 years ago

myfirstdatalogger commented 4 years ago

I am using an Nodemcu 1.0 ESP8266 and trying direct connection between remote and heatpump. No level shifter. With an potentiometer I can lower the voltage to below 1 Volt (Vtop) from the transmitting Remote>Heatpump. So the 3,3 Volt from the ESP8266 should be applicable. The ESP8266 is 5 Volt tolerant so the input should also be fine.

But: it doesn't work. I get an message "swSerHeatPump Wrong Package Received0". On my oscilloscope I see one signal constant HIGH, but no data. Remote gets H76.

Normal operation without ESP8266: (first start message send from the Heatpump>Remote) Normal start message long timebase Normal start message short timebase

The heatpump sends the first message when connected to the remote. When I disconnect the remote there is no data and only an high signal. How can this happen? I assumed the Heatpump wil still transmit data but no reaction from the end of the line (oscilloscope).

When connecting ESP8266 with Proxy software the heatpump also only transmits an HIGH signal, but no data.

Using Arduino 1.8.10 on Windows 10 ESP8266 libary from http://arduino.esp8266.com/stable/package_esp8266com_index.json The program geisha_aquarea_panasonic_arduino_esp8266_proxy with the included SoftwareSerial.

What am I doing wrong?

I fixed it. Remote and heatpump was switched, I misunderstood the code. Only using receive to readout the bus, no transmit until later.

Hi, Could you please share what you've reached with this project? Is the communication working? Thank you!

Communications is working, but I didn't do much after this.

This winter I want to develop an system that can:

  1. Log power and temperatures every minute
  2. Can remotely be switched on/off using ESP8266 WiFi capabilities over internet
  3. Adjust heating curve based on an temperature sensor in de room. For example fixed 20,0 degree Celcius at DS18B20.
  4. Gives pre-warning for deice

I am not experienced in programming. But you must set some ambitious goals ;-)

Wow, that sounds fantastic if it can be done :-)

Is it possible to chat anywhere which can be faster?

Could you please send a picture where you connect the Nodemcu with the heat pump? I have found there are more CN-NMODE connection possibilities..
