🔥 Advanced Heating Control

[panhans]

1. Navigate to Helper section
2. Create a Template Sensor
3. Paste this into template field and type in your weather entity:

{{ state_attr('weather.forecast_home','temperature') }}

//EDIT: But you can also have a look into your integrations. Maybe the sensor is simply disabled.

//EDIT: But forgot. You can also select your weather entity. No need for the outside sensor.

@panhans is this sufficient or do you need something else?

Advanced Heating Control

this one: eq-3 GitHub - dbuezas/eq3btsmart i dont know the diff between cal. and offset, there is offset only. trv_ez: hvac_modes: - "off" - auto - heat min_temp: 4.5 max_temp: 29.5 preset_modes: - eco - comfort - boost - away - Open current_temperature: 19.8 <-- ignore, its the ext. thermometer temperature: 20 hvac_action: heating preset_mode: comfort friendly_name: TRV EZ supported_features: 401 number.trv_ez_offset: min: -3.5 max: 3.5 step: 0.5 mode: box unit_of_measure…

[panhans]

This should work. Your climate gets calibrated using the offset entity in the default logic like my thermostats.

Many thanks @panhans extremely helpful

[vajdum]

thanks. I currently use generic calibration, is this correct?
Its not so easy to decide if one not know how cal. works.

I am still not sure about interaction between cal. and aggressive mode.
The latter would help the TRV to close so i know the boiler can be switched of if its warm in all rooms.

[panhans]

If your integration provides an offset entity there is no need for generic calibration.

But wait. Your’re right. Since I changed the adjustable aggressive mode I have to make some changes if it comes to the combination.

[vajdum]

I use this external thermometer which the integration adds as current_temperature to the TRV for displaying in climate card…

[panhans]

You need two temperature sensors. One next to your thermostat that is mapped to your climate entity. And a 2nd in the room as reference for the calibration.

//EDIT:

I reorder generic calibration and aggressive mode. First the new target will be calculated by aggressive mode and then the calibration offset will be added on top of the target temperature.

@panhans

ou need two temperature sensors. One next to your thermostat that is mapped to your climate entity. And a 2nd in the room as reference for the calibration.

How would generic cal function with no internal temp?
Couldnt the setpoint temperature be used?

[panhans]

That’s why you need a 2nd sensor next to your thermostat.

[vajdum]

Then i will try with aggressive mode and manual calibration. Currently i change it if its warm enough but still heating.

Hi @panhans,
I just wanted to get back to say that all Danfoss issues are now gone by me. After the update you mentioned there were still some small hiccups, but after some subsequent update they disappeared and now it’s all OK.

Now I’, going to buy you some coffee :-).
And I would suggest everybody who you helped should do the same – if a friend came to your house and debugged your heating, wouldn’t you at least buy them a coffee?

Thanks again, pal!

[Ziegelsandundspucke]

I would totally sign that. @panhans is taking care of every little problem or questions I have had. If its perfectly working or not (on my end it is), this project is totally worth it. I’ll also be refilling the coffee soon.

So after a lot of “try and error” and understanding at least a bit more i managed to fix the calibration issue (it seems so far). I had to modify the zha quirk for my thermostat.

I have _TZE200_h4cgnbzg and _TZE200_yw7cahqs devices and using this quirk (trv_saswell.py)

What i did you can read here (another user with a similar question for this device):

Double entity for temperature offset in Controls and Configuration for the Tuya TRV (TS0601 by _TZE200_h4cgnbzg)

Hi, i had the same issue with the calibration / offset slider and a blueprint i’m using. I modified the quirk (trv_saswell.py) a bit to make it work but just be aware i’m just testing this right now and it might not be the best solution The first slider from -6 to 6 for the calibration value with step size 1 does only accept int values. entity: number.<entityname>_nummer_temperature_calibration The second slider from -2.5 to 2.5 for the offset value with step size 0.1 does accept float…

But after a few hours i already see the calibration and offset values finaly match and are in the range the device can handle. Not sure it’s the most elegant solution and not sure it has no side effects i don’t discovered yet

At least i got sensible calibration / offset values between 0 and -2 now and no extremes like -20°C (instead of -2.0°C) anymore. Still not sure the device itself doesn’t mess it up with internal calibration functions. The AHC v4 blueprint seems to work fine so far. Fingers crossed

Advanced Heating Control ^{v4 RC1}

READ BEFORE UPDATE

Hey, guys!

I will update the test version of v4 now. This is the first release candidate. But there are some breaking changes:

• this version supports the new proximity integration. You don’t need to select an entity for this. Just define some persons, select them in your proximity service and select the zone of your proximity service
• some tweaks and options got some new selectors in order to bring more structure in this mess of UI. I recommend to resetup your automations. At least you have to tick your tweaks and options again. Sorry for this!

Thank for your help, debugging and making this piece of blueprint reliable for everyone.
It feels like a fight against standards and faulty devices. But the main thing is that it works in the end and your apartments are warm and maybe you save a little money, too.

[vajdum]

UI is much nicer/ understandable now.
Only for heating plan (i use scheduler) the optional options are not clear from the example.

I had to look twice to recognice the eco leaf icon with this lines arount on dark BG.
Maybe the little 2-leaf-plant is easier to spot.

[panhans]

Thanks for the ideas. I will check this.

Heating Plan / Adjustments will get a little overhaul next:

• multiple day filter
• scheduler filter
• comfort temp setter
• eco temp setter

[tirol3]

can you add switch for extarnal boiler etc. i am using sonoff thermostats my rooms i have dry contact on my combi and i have sonoff trvbz on my radiators. i want to use which room needs head trigger dry contact switch and all rooms is get heat dry contact off

[panhans]

You want to turn on the switch if any of the automation starts heating? Is this correct?
