Hello everyone! I wanted to share my recent success in integrating my Nefit Easy smart thermostat with OpenHAB. It’s been a fantastic journey, and I thought I’d walk through my experience in case anyone else is looking to do something similar.First, I must say that the process was smoother than I initially feared. I started by researching the best way to connect my thermostat to my smart home setup. After some digging, I came across a fantastic node.js tool called easy-server by Robert Klep. It acts as a bridge between my thermostat and OpenHAB, making it easier to retrieve and send data.The setup involved a few steps. I installed node.js on my system, then used npm to install the easy-server package. I had to set up some environment variables with my login credentials, which was straightforward. Once everything was configured, I started the service and tested it by sending a simple HTTP request. The response was almost instantaneous, which was really encouraging.Next, I moved on to defining the items in OpenHAB. I decided to track the room temperature, the set temperature, the system pressure, and whether the boiler was active. I also included a helper item to retry failed API calls after a short delay. This part was a bit tricky, but with some trial and error, I got it working perfectly.The real magic happened when I started writing the rules. I set up a rule to fetch the latest status every 30 seconds. This rule extracts the necessary data from the API response and updates the corresponding items. I also added a rule to retrieve the daily gas usage after midnight, which logs the data in InfluxDB for later analysis.One thing I learned is the importance of error handling. I made sure to include logging for any failed API calls and set up a retry mechanism. This has been invaluable in maintaining a stable connection to my thermostat.To make everything user-friendly, I created a simple sitemap. It displays the current temperature, the set temperature, the boiler status, and the system pressure. This gives me a quick overview of my heating system at a glance.Overall, I’m thrilled with how everything turned out. My thermostat now seamlessly integrates with my smart home, providing real-time data and allowing me to control my heating system remotely. It’s been a great way to enhance my home comfort and energy efficiency.If anyone else is looking to integrate their Nefit Easy thermostat or has questions about the process, feel free to reach out. I’d be happy to help!
