Hello. Could someone with the right knowledge dive into the code and add a minimum temperature? Today the lowest is 4 degrees when using termostat. Is this possible? ---

The minimum and maximum are set for the entire capability: ![Screenshot 2020-11-30 at 07.55.07](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/6/e/6ef06d6c40c11865ce0bc31ef1b2c62315b1261d.png) ---

Thank you for the reply, but what does this mean? Can’t i change it manually then? And are therefore any good reason for why there’s is 4 and 35? ---

It means you can’t change it manually, and the developer also can’t change it, it’s fixed by the system. I have no idea why Athom choose those values specifically. ---

Should be an easy fix for athom to change it ---

Well actually the ranges are udjustable by the developer with capabilitiesOptions, but not sure why you’d want **thermostat** that is below 4/5 degrees, that is _really_ cold for in your house. ---

Hello and thank you for your answer. I use it to shower temperature from others sensors. That’s why i want it to show under 4 degrees ---

Then better use measure\_temperature instead of target\_temperature ---

I experienced it to be to slow to update, but perhaps my glow was not set up right. Do you have an example for how to set uo the flow? I just use: When temperature changes Then " measure\_temperature" and linked it to the virtual device ---

Sounds about right. And u also chose the correct capability for the virtual thermostat? ![image](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/1/6/1619d534ceab184e3b70ff7c5daac670d9962702.jpeg) ![image](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/6/f/6f607ccd5d415732df37bc1e5dbe64f4ea2f2caa.jpeg) ---

Hmm, ive tried them both. Do you know what the difference is? I don’t know your language but I see you have two different names on the temperatures, i have the same in both of them and don’t know the difference ---

Like I told u before: use measure instead of target. ![image](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/b/d/bd23cf32aefdd541b1b1bac8817861607b815e82.jpeg) Target is to set a temperature for like heating. Measure is to see how cold it is outside ---

And the flowcard should look like this: ![image](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/e/e/ee8db573752428167458cad94358d4ab54af8126.jpeg) ---

Yes, ive used target before, but changed when you told me. The problem has been that in you picture it says " target temperature, and measure temperature" In mine it has had the same name, translated from target temperature, so it has been some difficulty to see what the difference was. I have now changed to English-speaking and i see now that it is two different names. Thanks alot for all the help !! Hope this works for me. ---
