Hey everyone! I wanted to share my experience with using Shelly devices to control my heating system. I’ve been using a Shelly 1pm plus, Shelly H&T, and Shelly Button 1 to automate my oil radiator in the bedroom. It’s been a fun project, and I’ve learned a lot along the way!
Initially, I set up the Shelly H&T to monitor the room temperature and control the radiator using the built-in thermostat function. However, I noticed that the temperature fluctuations were quite significant. For example, the radiator would turn on at 19.5°C and off at 21°C, which wasn’t ideal for maintaining a consistent temperature. To address this, I created some scenes to simplify the temperature control. I set the radiator to turn on when the temperature drops below 20°C and off when it reaches 20°C. This worked much better!
I also wanted to add manual control, so I connected a Shelly Button 1. I configured it so that a short press turns the radiator off, and a long press turns it on. However, I ran into an issue where the scenes would interfere with each other. If the scenes were set to repeat, the button wouldn’t work properly. To solve this, I created separate emergency on/off scenes for the radiator. It’s not the most elegant solution, but it gets the job done!
One thing I’m still struggling with is fine-tuning the temperature settings. The Shelly H&T has a resolution of 0.5°C, which sometimes causes delays in the radiator turning on or off. For example, if the temperature is already at 19.5°C, the scene might not trigger immediately. I’ve tried adjusting the thresholds, but it’s still a bit hit or miss. I’d love to hear if anyone has a better approach or workaround for this!
Overall, I’m really happy with how the system is working. It’s given me more control over the heating, and I can even adjust it remotely from my phone. The Shelly devices have been reliable, and I appreciate the flexibility they offer. If anyone has suggestions for improving the setup or tips for better temperature control, I’d love to hear them!
Cheers,
Maik
