Thermostat Smart Home Upgrade

To slash my heating bills, I decided to turn my thermostat into a smart one. Since I live in a rented apartment, I'm not allowed to make any significant modifications to the heating system. This device is fairly simple yet has great potential. The frame clips onto the thermostat. You don't need any screws or other mounting hardware. Installation and removal take literally under 5 seconds. The concept is straightforward: a microcontroller controls a servo, which operates the thermostat via a wheel. Originally, it was just an Arduino that turned off the heating after a certain time. The timer can be set using the button and the LED. Variant two uses a Wemos D1 mini connected to a smart home (ioBroker) via MQTT. This allows the old dumb thermostat to be controlled via the internet and react to events. So, it's able to do everything that an expensive smart thermostat can do at a fraction of the price. Hardware: Wemos D1 mini or Arduino nano any 9g micro servo 3mm LED push-button (maybe a transistor if your servo is making a hissing noise) I'm unsure how I'd be able to or if I should upload the Arduino code. I wrote it myself, and honestly, it's pretty terrible, but it works. I'm a beginner in programming. If it's requested, I'll upload the code, but be sure to see a mess! I tested the design for several months and never had a failure. So, I'm pretty confident to say that it's very reliable. None of the parts need support.
