+## Maintenance
+
+As far as gate maintenance is concerned, I had a lot of problems to solve when the prototype was installed. I'd never restored an electric gate before, nor even designed a system of this kind. So this was a first, and I was able to make a lot of mistakes in the original design, both physically and in the program.
+I was therefore often called upon by the gate to repair it, improve it and make it work optimally.
+
+However, since installing the new PCB (at the time of writing, it's already been 2 months), I haven't had to make any changes to the portal. It hasn't broken down since, and I'm very happy about that.

 ## Points of improvement
 
 ### Security : No rolling code
 
-The EV1527 433MHz receiver module does not allow code rolling as the HCS301 KeeLoq protocols do. Nevertheless, since the gate does not give any access to the interior of a house, this point does not really pose a problem.

+## Conclusion
+
+In conclusion, the electric gate restoration project was launched in April 2022 with the aim of seeing it functional again after more than 15 years. The gate gave access to several houses, so it was essential to ensure that its operation was easy and hassle-free. The gate was no longer functioning since the power supply had been replaced by a single-phase supply.
+
+The project began by assessing the condition of the gate, which included a three-phase motor to be converted to single-phase, mechanical limit switches and a broken photoelectric sensor to be replaced, as well as the need to completely overhaul the gate's electronics. The project also involved developing a reliable, easy-to-install electronic board, called LiHoCo Yard gate PCB v1.0, as well as other components such as mechanical limit switches, a photoelectric sensor, a warning light, a 433MHz RF remote control and a 25µF 450V capacitor.
+
+On the software side, ESPhome was chosen as the solution for implementing the gate system. The program, electric-gate.yaml, was developed with ESPhome for the ESP32.
+
+The development process involved several stages. Firstly, the feasibility of the project was tested by converting the three-phase motor into a single-phase motor using a 25µF 450V capacitor. The motor was checked for correct operation, and the gearbox oil was also changed. Other non-functional components were not a problem at this stage.
+
+A prototype circuit was then created to quickly develop and test the program with ESPhome. This enabled further improvements and modifications to be identified. The main components, such as the limit switches and photoelectric sensor, were installed and connected in accordance with the circuit design. This prototype was monitored over several months to identify and resolve any problems.
+
+Based on the lessons learned from the prototype, a new electrical board (LiHoCo Yard gate PCB v1.0) was designed, manufactured and installed to improve the reliability and professionalism of the gate's operation. Once the new PCB was installed, the gate was fully functional and operational.
+
+As far as maintenance was concerned, several difficulties and mistakes were made at the outset due to a lack of experience in restoring electric gates. However, following installation of the new circuit board, no further modifications or repairs were required, and the gate has been operating optimally for two months.
+
+One potential area for improvement is the security aspect, as the EV1527 433MHz receiver module used does not support code rolling. However, as the gate does not allow access to the inside of the houses
