See picture below. Google has been allowing the ability to select external temperature sensors for years. Ecobee has something similar. Perfect for people who have thermostats in a completely different part of their house.
I use this every night to ensure the temperature in my son’s bedroom (which is usually the coldest) is set to a more comfortable temp. Yes, this slightly raises the temp in the whole house, but better than trying to guess what temp I should raise the main thermostat temp to get a better temp upstairs.
Would love to finally be completely off the Nest app, and see HA implemented even better by allowing for usage of temp sensor templates, so I can create my own sensors to use, like “upstairs”, which would be an average of all temp sensors upstairs.
I don’t believe this would be an integration. This would be an update to the standard climate card that allows for adding 2 or more additional temperature sensors to the UI, and the selection of one of them as the set point. That way, just like the image, you can select which temp sensor you want to use from the UI.
Unfortunately everything I’ve read says that the generic thermostat integration can’t do what I’m stating. While, yes, the code can be written to use a different temp sensor as the one providing the set point, it lacks the flexibility of manually changing the sensor via the UI throughout the day. As far as I’m aware, to do so, I’d have to update the sensor used in the code for the integration everytime which doesn’t pass the WAF.
Because that would just display the other room temps. I’m trying to not just see the other temp sensors around my house, but to make one of them a set point for the thermostat.
The set point is the target temperature.
I now (think I) understand you want to be able to select the source temperature sensor at will, but your feature description is a bit confusing.
I would use a generic thermostat, with the source sensor being a template sensor that would take your son’s room sensor past a certain time, and another one otherwise.
To @nickrout 's suggestion, would I be able to just create an input_select dropdown and a template as the source temperature with generic thermostat? Additionally, would I be able to create automations that set the source from the dropdown automatically based on time of day, etc.?
@nickrout - Any help you can provide as well would be greatly appreciated.
I’m a bit stuck at the moment on two different parts… And perhaps this is where I need to revise my feature request.
I’m using a Nest thermostat, so my thermostat appears as a climate entity. The generic thermostat requires a switch to control heating OR cooling (on/off). Would prefer if I could use this and just move between HVAC modes
I created a template sensor that takes the input from the “Thermostat target” dropdown and makes related room temperature the state of “Selected room temperature”. However, when setting up a generic thermostat, I can’t select “sensor.selected_room_temperature”. The helper is only allowing me to select individual temperature sensors.
Goal: Be able to select a room from the dropdown. See the thermostat change to reflect the current temperature of a room. Then manually adjust the thermostat to what temperature I want the desired temperature to be for that room. Yes, the house will heat or cool to achieve this but it gives me more precise control over my climate controls.
Note: The dark thermostat card at the top shows the current temp of my living room at 69 F, with a current heating level of 66 F, so that’s why heating is currently off. While it looks like it’s all working together, it’s not. The dark thermostat changes the room temperature (69 F in this case) only in the Nest app.
This has been a long-time known annoyance, for me included. If I recall it has to do with something on Google’s end with the Nest API and how it doesn’t even work with Google’s own temperature sensors and why we even need the Nest Protect integration.
I was just thinking a few days ago that it could maybe be done with a script that is triggered by a present detection or a dash button that would tell the thermostat to set based on the current temp and the temp at the sensor. Haven’t started one but it was just me brainstorming.
Not quite what you’re looking for but, hopefully, this might be useful.
I’m using the Thermostat card and a template that averages two temperature sensors (in a large open plan area). The template acts as the ‘current temp’ for the Thermostat.
You could write a template that, based on time or the state of a helper, returned the temp state of one or the other sensor (rather than averaging).
I would think that you could, if you want to choose from multiple sensors, select the required sensor from a list and that is used by the template (ie as the current temp of the thermostat).
