My bad, I just noticed this option in the DIYless GUI:
@Dujith, am I correct in assuming that the Resend-node in Node-RED is needed to prevent this failsafe from triggering?
I have somehere an error in this code

You got an extra % at the end there.
Also, always define a default value if for some reason the sensor wont work.
{% set masterbedroom_td = (states('sensor.target_temperature_br') - states('sensor.ble_temperature_clim_master_bedroom') | float(18)) %}
{{ (states('sensor.target_temperature_br') | float(18)) }}
Just a pointer which I’ve spent a while try to figure out!
I think the {% if index_td == 1 %} should start at 0 and then run through to 1 - the number of rooms you have.
I had issues where the list was picking out the second largest temperature difference!
Credit to Chat GPT AI who help me haha!

You know, you are right. I never realized that it would count from zero.
My lack of programming skills shows 
Seem thats always the case be it Jinja or Python.
Ow Frell me… I already took that into account. The living room (woonkamer is 0) so i just check for 1 and 2 and if its 0 then take the living room value.
I noticed when it stopped working correctly after changing it

Which sketch are you using? The DIYLESS Git Hub one or the modified version by Joparmen?
I think I have everything working other than, for some reason the set values don’t seem to trigger the boiler to start heating. I’ve checked in MQTT explorer and they are been sent over correctly, but the get topics never seem to update.
I am running the Joparmen version though.
Cheers, happy to help.
Maybe I’m impatient… It seems to have the values now…
still not working here. I receive state: unavailable

Lets take a step back and just insert this in the Developer Tools → Template
{% set masterbedroom_td = (states('sensor.target_temperature_br') - states('sensor.ble_temperature_clim_master_bedroom') | float) %}
{{ masterbedroom_td }}
And just this:
{{ states('sensor.target_temperature_br') }}
{{ states('sensor.ble_temperature_clim_master_bedroom') }}
Also you should always define a default value for if the sensor bugs out or any other startup problem when the sensor is unknow for some reason
So what do those 2 give?
The first one
TypeError: unsupported operand type(s) for -: ‘str’ and ‘float’
The second one
19.0
20.7
{% set masterbedroom_td = (states('sensor.target_temperature_br') | float(18) - states('sensor.ble_temperature_clim_master_bedroom') | float(18)) %}
{{ masterbedroom_td }}
I think you need to define both as floats (and give them a default value)
Right you you just specified the last one as a float and HA is seeing the first one as a string, and since you cannot subtract a float from a string, you get that error.
thank u this works. another problem, how can I exclude the rooms with a negative difference from the list? For example living room is 2 degrees to warm, the rest of the room is 0,5 degrees below set point. How do I ban the living room from determining the temperature?
You dont. 2 degrees to warm means its -2 difference. Thats smaller then 0,5 so it will pick the 0,5 difference
Hello,
I’m trying your code for the virtual temp and set temp.
I have more zones and tried to extend it.
It doesn’t seem to work, Can someone guide me what I’m doing wrong?
this is what I added in the “sensor.yaml”
Thanks in advance.

Having said that, you never seemed to define this is a template sensor.
Keep in mind that my code is old and had a few revisions. Important thing is to add default values so these get used when sensors are offline.

Note that this is the old style as there was an issue getting the friendly_name to behave correctly in the new style. There is a long debate around this: Add (bring back) friendly_name to template sensors
But since the old style does not show signs of being decraped, i will use it like this
Edit: i’ll mark this for future reference.
For now (31-7-2023) This is the code i use. Adjusted to use default values and some cleanup.

Hello Dujith,
Thanks for your reply.
I forgot to mention that the code I added was only the part for these 2 sensors, I already defined the template sensor.
download the sensor.yaml here
When using this I get the following error while doing “Quick reload”
Failed to reload configuration
Cannot quick reload all YAML configurations because the configuration is not valid: Invalid config for [sensor.template]: invalid template (TemplateSyntaxError: unexpected ‘}’, expected ‘)’) for dictionary value @ data[‘sensors’][‘setpoint_cv_virtual’][‘value_template’].

Just need to add a ) or remove the one at the start: (state_attr
Check all the lines for the missing ) 
Thanks all for your help, that did it!
It has been interesting to read. I might end up pitching this to my moms association of owners.
The first alteration I would try is moving list_room_td up one line and try to use it for max_td to make things a bit more DRY.
