Help with climates

[brazoayeye]

Hello, my heatpump has these addresses for the water heater:

status 0x4237
set 0x4235
enable 0x4065 (1 = Enabled, 0 = disabled)
preset 0x4066 (0 = Eco, 1 = Standard, 2=Power, 3=Force)

I tried this thing

  debug_log_messages: false
  debug_log_undefined_messages: false
  nasa_client: {}
  devices:

      min_temperature: 30
      max_temperature: 60
      temperature_step:
        target_temperature: 0.1
        current_temperature: 0.1    

But it doens't work as expected (economy - Eco)

And how are words translated into numbers? Maybe with lambdas, but I haven't found anything in the example.

I also have a similar problem with Heating
status: 0x4238
set: 0x4247
enable: 0x4000
mode: 0x4001 (0 = Auto, 1 = Cool, 4 = Heat)

Thanks

Please attach your yaml config. What ESPHome and Samsung NASA component version are you using?

For select components the order of the options is important and determines their index value (starting at zero).

Also, "Economy" can't be used as a text label as that is already used as a standard climate preset option. 'Eco' is used instead for the custom preset to avoid conflicts. But it's the underlying numeric value that is important and that is determined by its position in the list.

Hello Beormund, thanks for the impeccable work. I made 99% of the idea using your code and only few minor things could be improved.
I realized that web server doesn't expose climate presets, but they are visible with hass.

I took a look to the code and from what I understood all components are indexed by the message address and informations are ignected ignoring users one.
I solved creating another select template with my items and sending-getting addresses from the base one. Works well even if

• imho user setting should override codes one
• in selects there should be a mapping name > value, maybe an array with empty strings is unused keys is good enoght if only small values are used.

I've also seen that I can't setup a select with a custom address not mapped (address 0x8003)

The heating preset should have as HVAC modes ["Off", "Auto", "Heat", "Cool"] and that should be mapped to two addreses.
In my config I can select ["Off", "Heat"] to enable and ["Auto", "Heat", "Cool"] for the mode. It's strange to select Heat + Cool to Cool, but it works so...

Select componenrs are weak in ESPHome in my view - no ability to assign a value to a string option. It would be straightforward enough to allow a mapping in a custom component for a select. Let me have a play.

Allowing to overwrite options needs discussion due to the risk of sending incorrect values to the MIM board.

Mode and preset are tricky when it comes to catering for both DHW and heating. Mode as you can probably see is currently tied to a binary switch and preset to a select. Mode could be altered to bind to a select - although that might be ovetkill for DHW. TBH I hadn't anticipated cooling to be a requirement for a heat pump.

@brazoayeye - I have added 0x8003 on the test branch. Please can you test?

[brazoayeye]

Works, well even if it's writable (i inserted it like a sensor). I can make a workaround with a template or something similar.

Looking at my config there are also a lot a missing measurements units (I added them only where needed). But it's not a problem since the user can add them manyally in the yaml.

I discourage you to hardly customize entities because espHome breaking changes will cause more work to fix, for an aesthetic feature.

Thanks
