Does anybody know how to add to yaml DWH (Domestic Water heat) ?

[smartminjos]

I am trying to add DWH to yaml but i am total newbee. I want to see in HA my DWH temperature and chage the modes and target temperature.
I find this in other fork but donno how to add here but does not work with this repository:

ustom_climate: # Didn't like this line when source: github://omerfaruk-aran/esphome_samsung_hvac_bus@main
- name: "Water heater"
status_addr: 0x4237 # mandatory address regarding status temperature
set_addr: 0x4235 # mandatory address regarding setpoint temperature
set_min: 40 # optional, default = 25°C
set_max: 50 # optional, default = 65°C
enable_addr: 0x4065 # mandatory enabling address, only 1/0 should be written there. Look at mode sub section
# By default the value is set = 1 when HA send a value > 0.
preset:
addr: 0x4066 # Address for presets
ClimatePreset0Value: 1 # CLIMATE_PRESET_NONE => 1 Standard
ClimatePreset1Value: -1 # CLIMATE_PRESET_HOME
ClimatePreset2Value: -1 # CLIMATE_PRESET_AWAY
ClimatePreset3Value: 2 # CLIMATE_PRESET_BOOST => 2 Power
ClimatePreset4Value: -1 # CLIMATE_PRESET_COMFORT
ClimatePreset5Value: 0 # CLIMATE_PRESET_ECO => 0 Eco
ClimatePreset6Value: -1 # CLIMATE_PRESET_SLEEP
ClimatePreset7Value: 3 # CLIMATE_PRESET_ACTIVITY => 3 Force

Hi, I forked that repo time ago to implement custom_climate but it's not working due to latest espHome changes.

I moved to another similar project but focussed on nasa protocol.
I suggest to have a look here

Beormund/esphome-samsung-nasa#12

@brazoayeye i was using you repo until 2025.11 came and since than i had to move back to here ..... all works except custom climate of course :))))
Will have a look there, many thanks.
Means your repo is dead for now ?

Yes, because I’ve found alternatives that do almost the same thing, so it’s pointless to fix or improve it.

I added a PR a while ago for dwh: #145 & #158

This is how to stick it in your config:

water_temperature:
  name: "Hot Water Current Temperature"
  id: hot_water_current_temp
water_heater_mode:
  name: "Hotwater Mode"
  id: hotwater_mode
water_target_temperature:
  name: "Hot Water Target Temperature"
  id: hot_water_target_temp
