Ignore me... the mysensors API version was set to 1.4 :face_palm:

Hi folks,

Just resurrected my home assistant setup after a hiatus (previous install was early HA from 2021), I had my heatpump working before. But with the newer version of HA I'm getting the following logged.

Hey @BearWithBeard

I'd not put in a version: as I'd assumed it would default to most recent... those assumptions always get you!

Pretty much working now, many thanks!

I've also run the example mqtt.py from pymysensors outside of home assistant to see if my heatpump sensor was generically sending rubbish. But that didn't throw out any errors.

So could this be a problem with the mysensors integration in home-assistant?

TIA

Hi folks,

I'm having a bit of an issue with re-building my esp8266 mqtt gateway using the make file from the makeEspArduino project.

What I'm seeing is an issue compiling the following:

/home/sf/Arduino/libraries/MySensors/core/MyGatewayTransportEthernet.cpp:103:1: error: 'EthernetServer' does not name a type
EthernetServer _ethernetServer(_ethernetGatewayPort);
^
/home/sf/Arduino/libraries/MySensors/core/MyGatewayTransportEthernet.cpp:118:8: error: 'EthernetClient' does not name a type
static EthernetClient client = EthernetClient();

From the looks of it the defines at the start of my sketch are not being passed down to the MySensors components As those types are defined a few lines above the ones with the error in an ifdef block.

Before I disappear down a rabbit hole, does anyone have any suggestions as to how I can address this error?

TIA

Steve

Hi can you add the kicad files for the latest rev pls?

Hi,

So as I see it I would need to use the hardware serial for the connection to the heatpump and then create a software serial for debug messages. So something like this:

#include <SoftwareSerial.h>
SoftwareSerial mySerial(10, 11); // RX, TX

// Enable debug prints
#define MY_DEBUG
#define MY_DEBUGDEVICE mySerial
#define MY_BAUD_RATE 9600

So the next question is how to present the heatpump to the gateway. Would you create one child id and then define each type of sensor/metric or is there a one-to-one mapping:

#define CHILD_HVAC 0

MyMessage msgHvacStatu(CHILD_HVAC, V_STATUS); // Status: ON, OFF
MyMessage msgHvacSTemp(CHILD_HVAC, V_TEMP);    // Set Temp
MyMessage msgHvacRTemp(CHILD_HVAC, V_TEMP);    // Room Temp
MyMessage msgHvacFanSp(CHILD_HVAC, V_HVAC_SPEED);    // Fan Speed

or

#define CHILD_HVAC_STATUS 0
#define CHILD_HVAC_STEMP 1
#define CHILD_HVAC_RTEMP 2
#define CHILD_HVAC_FANSP 3

MyMessage msgHvacStatu(CHILD_HVAC_STATUS, V_STATUS); // Status: ON, OFF
MyMessage msgHvacSTemp(CHILD_HVAC_STEMP, V_TEMP);    // Set Temp
MyMessage msgHvacRTemp(CHILD_HVAC_RTEMP, V_TEMP);    // Room Temp
MyMessage msgHvacFanSp(CHILD_HVAC_FANSP, V_HVAC_SPEED);    // Fan Speed

Hi Folks,

just trying to figure out how to get started with controlling a heatpump via a serial connection. I've found this blog entry which is my starting point. At the moment I'm unsure if I can connect the hardware serial of a pro mini to the heat pump and be able to debug it. Or would this require the use of a software serial port, or even springing for a board with more than one serial

Any pointers in the correct direction appreciated
