ha-stiebel-control

ha-stiebel-control is a ESPhome / Home Assistant configuration to monitor & configure Stiebel Eltron Heating Pumps via a CAN Interface. It requires setting up an ESP32 Microcontroller with a MCP2515 CAN-Tranceiver and some configuring in Home Assistant. It is based on the great work of the Home Assistant community, especially the work of roberreiters and Jürg Müller.

Installation

ESPHome

• Set up a new ESPHome Project "heatingpump"
• Copy the Content of heatingpump.yaml to the new project
• copy the folder stiebeltoolsto your /config/esphome folder (full path should be /config/esphome/stiebeltools)
• Change the WiFi Credentials to yours
• Change the GPIO Pins under spi and can to your HW configuration
• You may want to check/change the CAN IDs of the Manager, Kessel, etc. In order to do so, you have to change them in two places:
  • stiebeltools\heatingpump.h:

    static const CanMember CanMembers[] =
    {
    //  Name              CanId     ReadId          WriteId         ConfirmationID
    { "ESPCLIENT"     , 0x700,    {0x00, 0x00},   {0x00, 0x00},   {0xE2, 0x00}}, //The ESP Home Client, thus no valid read/write IDs
    { "KESSEL"        , 0x180,    {0x31, 0x00},   {0x30, 0x00},   {0x00, 0x00}},
    { "MANAGER"       , 0x480,    {0x91, 0x00},   {0x90, 0x00},   {0x00, 0x00}},
    { "HEIZMODUL"     , 0x500,    {0xA1, 0x00},   {0xA0, 0x00},   {0x00, 0x00}}
    };

  • heatingpump.yaml: Look for these blocks in the lower part of the file

    #########################################
    #                                       #
    #   HEIZMODUL Nachrichten               #
    #                                       #
    #########################################
    - can_id: 0x500
      then:
        - lambda: |-
            unsigned short canId = 500;

Home Assistant

Entities and Helpers

• place the file packages/ha_stiebel_control.yaml in your /config/packages/ folder in Home Assistant.
• add the package folder to your configuration.yaml under homeassistant (if not already set up)

  homeassistant:
  packages: !include_dir_named packages

  Dashboard

• Install the lovelace card apexcharts-card
• Install the lovelace card lovelace-mushroom
• Create a new Dashboard, switch to RAW mode and paste the content of dashboard.yaml. The result should look similar to this:
