Automating radiator control

hi guys.
I'm looking to automate the in my apartment.
I se to solutions.
the cheap solution:
get an ATmega328P, servo motor, and potentiometer.
use the potentiometer to input and adjust the heat. have a timer code that shuts the heat off at night. I do this by 3D printing an engine holder for the stepper motor, and a gear clamp (se the pic) That goes on the heat adjuster for the radiator. power the whole thing with a battery. The problem is mainly the arduino/ATmega328P ability to tell the time as i see it.

The more advanced approach would be to use and ESP8266 wifi unit to control the motor and the use a NTP protoco tell the time, and thereby knowing when to shut of the heat. This is of course a more complicated code but I'll figure it out.

So the question is, is using an ESP8266 and a 9-volt battery the best solution and how long do you think the battery will last? Is there a way to use the ATmega328p Since this will be cheaper?

No, About 20 to 30 minutes.

If you are using a 9V battery like this.


Expect short run times and many issues involving low power.

Have you measured the force required to change the setting? Ours are very stiff.

I suggest you give this a read: EVERYTHING YOU NEED TO KNOW ABOUT THE 9V BATTERY. Then once you understand all of that, like battery chemistry you give this a read: Development of Power Consumption Models for ESP8266-Enabled Low-Cost IoT Monitoring Nodes. Then you get back to us on why a PP3 type 9 volt battery is a poor choice.

There are plenty of ways to have a real time clock working with an Arduino. Google is your best friend on that note.

Finally please explain your project in detail. Details include your proposed code and a schematic of your planned wiring. Less a good description and drawing about all I can tell you is that a 9 volt PP3 battery is a bad idea and will have a short life.

ok tnx! defently not use a battery!
I'm just at the start of the project and have therefore not written any cold yet as of now I'm ill looking for what components why to buy why and a place to start for thank you I'll try to delete the top and come back with a better description of the project later

Real time clock modules are pretty cheap and generally have battery backup.
