You managed to adjust levels MID/HIGH/ECO? I’m interested! :slight_smile:

Yeah, I’m still interested!

@Noria any chance you can still help us out :slight_smile: I am becoming desperate to avoid using Eurom app while having everything nicely automated in Home Assistant :smiley:

@Noria,

How did you manage to add the heater via Tuya to HA?
I only managed to add the heater as a switch (On/Off).

How did you add it?

I thought maybe addind the device as climate. But what are the values?

Hi guys, sorry, I will let you know in the evening, or tomorrow. If I forget (I get no notifications from this place) just remind me on [email protected]

Hi, so this is how you do it:

Open file on HA …\config\custom_components\localtuya\climate.py
In climate.py you can find HVAC_MODE_SETS (line 59 or around) and
add new set:

"manual (m) / automatic (p)": {
        HVAC_MODE_HEAT: "m",
        HVAC_MODE_AUTO: "p",
    },

in the same file find PRESET_SETS (line 94 or around)
and add

 "low/mid/high/off": {
        PRESET_NONE: "low",
        PRESET_AWAY: "mid",
        PRESET_HOME: "high",
    },

Now you can set the device:
Protocol version 3.3

Preset is not corresponding to real values but you will find what is what. I do control heaters from the AppDaemon so I do not care. It may be possible to fix that as well.

Thanks for your config @Noria I will test it and reply my experiences
Another thank you for the Quick follow up of your personal gmail notify :slight_smile:

Great. BTW, it really communicates only locally with HA. I’ve put heaters into separate network without access to rest of home network and it stopped working.

@Noria

Hi Noria;

Thanks for all the work you’ve allready put into this. It helped me extremely well!
Now I try to take it one step further (off course we would like to…) For setting, I have 4 options high, mid, low and off. Especially this last one to my opinion is interesting.
I would like to use these High and Off for switching on the heater, instead of the general ‘Off’. The general off appaerently puts my heater back into automatic mode, which I don’t want.

Did you find a way to include the ‘off’ from this preset/setting. Up to now I’ve tried some things, but without any succes.

The Eurom Heaters have to be added in Home Assistant with the Tuya integration. Even better with the LocalTuya integration. There are multiple leads in this topic, and on the internet to get this done. I’ve done this several weeks ago, with the use of this guy on youtube (adviced to set speed to 0,5, wow he talks fast!) https://youtu.be/VCd0kYWLvMQ
Beside that the description from Noria is the needed addition to get the eurom heaters added!

Hello,

as far as I understand it, preset is not there to turn it on/off. It is there to set the power of heating.
Use “hvac_mode” if you want to set manual / auto / off. It is the main state of the climate.
Using appdaemon you can even call turn_on / turn_off

28

@Noria, is it possible to post your (complete) climate.py or the relevant parts of it? I’m trying to get it to work, but only partially suceeded. I’m on the latest HA versione 2023.10.5 and latest localtuya integration version

29

I figured it out how to set the heat levels. You can use custom preset sets.

Here is a snipped of my climate.py file. Especially the last set will be interesting for you.

PRESET_SETS = {
    "Manual/Holiday/Program": {
        PRESET_AWAY: "Holiday",
        PRESET_HOME: "Program",
        PRESET_NONE: "Manual"
    },
    "low/mid/high/off": {
        "off": "off",
        "low": "low",
        "mid": "mid",
        "high": "high"
    }
}

In my case, I also changed the value of “Presets DP” to 5. In the example of @Noria the DP ID was set to 101. This DP ID might be different on other eurom devices. To be sure, you can check the device debug in Tuya IoT platform.

Thanks for calling out. Nevertheless it is working acceptable for me like it is now, so I don’t want (or dare) to try implementing your possible solution :wink: Doesn’t take my appreciation for your input away.

Just bought a Eurom Alutherm 1500.
I did exactly this and “Presets DP” is indeed also 5 for me. I also had to change the HVAC_MODE_SETS to “manual” and “auto” instead of “m” and “p”:

HVAC_MODE_SETS = {
    "manual/auto": {
        HVAC_MODE_HEAT: "manual",
        HVAC_MODE_AUTO: "auto",
    },
    "Manual/Auto": {
        HVAC_MODE_HEAT: "Manual",
        HVAC_MODE_AUTO: "Auto",
    },
    "Manual/Program": {
        HVAC_MODE_HEAT: "Manual",
        HVAC_MODE_AUTO: "Program",
    },
    "m/p": {
        HVAC_MODE_HEAT: "m",
        HVAC_MODE_AUTO: "p",
    },
    "True/False": {
        HVAC_MODE_HEAT: True,
    },
    "1/0": {
        HVAC_MODE_HEAT: "1",
        HVAC_MODE_AUTO: "0",
    },
    "manual (m) / automatic (p)": {
        HVAC_MODE_HEAT: "manual",
        HVAC_MODE_AUTO: "auto",
    },
}

PRESET_SETS = {
    "Manual/Holiday/Program": {
        PRESET_AWAY: "Holiday",
        PRESET_HOME: "Program",
        PRESET_NONE: "Manual",
    },
    "low/mid/high/off": {
        "Off": "off",
        "Low": "low",
        "Mid": "mid",
        "High": "high",
    },
}

Working 100%, tnx!
