Hi All
Thank you for everyone that shared their experience on this. I have re-used a bunch of learnings from this post and others and completed an integration from my Geyserwise Max to Home Assistant. This should also be possible with the Delta and TSE models but I have not tested that.
Sorry for the lack of media in the post, as a new user I seem to be limited to only one media file per post.
Steps I followed:
- Replace Geyserwise Max panel board(3 temp digit model, 2 digit model is not compatible) with the IOT/Tuya panel board.
- I have standardised on Tasmota for firmware so flashed ESP 12F with latest Tasmota firmware and replaced Tuya WBR3 chip.
- Configure Tasmota with option Tuya MCU (54) and MQTT back to Home Assistant.
- Including my sensor file and lovelace configuration for Homeassistant below.
Step 1 & 2: Follow the steps as described by @kidcolt here
Step 3: Ensure you configure the Tasmota module type as Tuya MCU(54), this configures the ESP to interface with the tuya MCU module via the UART.
In order to periodically send the Tuya messages recieved on the UART but avoid unneccessary cyclic messages set the following options in the console settings.
SetOption66 1
SetOption137 1
Step 4: Add new sensor configuration for the Geyser. Here is my geyser1.yaml file. Make sure you correct the mqtt topic to reflect your settings in Tasmota.
I still need to map the correct error code values to human readable descriptions for the geyser1_error_code sensor. If anyone know the correct values for each error type please let me know.
# Requires:
# Transplant WBR3 chip transplanted with ESP-12F
# Tasmota configured for device type TuyaMCU (54)
# SetOption66 1 in tasmota
# To avoid some cyclic MCU <-> ESP messages enable SetOption137 1

This is what my geyser lovelace configuration looks like. I use the custom Mushroom and apexcharts-card Frontend extensions installed from HACS.
Here is the yaml for that display.

This allows monitoring the temperatures, status of various components and control the element through home assistant.
I quite like the graph which shows the blue collector temp vs the orange geyser temperature. The red indicates the element runtime overlayed onto the temperature.
Enjoy!
