Hi everyone, I’ve been exploring the world of smart home automation lately, and I wanted to share my experiences with integrating a smart thermostat valve into my heating system. I recently purchased the HY368 thermostat valve and paired it with a smart gateway, planning to switch to zigbee2mqtt in Home Assistant soon. While the setup process was smooth, I encountered some interesting behavior that I thought I’d document and see if others have experienced similar issues.
Initially, I noticed that when I set the desired temperature, the valve would open significantly but then start to close very slowly, which was a bit puzzling. For instance, if I set the temperature to 20°C in my living room, the valve would open up to around 75%, heating the room to about 21°C, and then begin to close in 5% increments. This slow closing behavior led to the temperature occasionally spiking up to 22.5°C, which was a bit uncomfortable. After some experimentation, I found that manually setting the temperature much lower would force the valve to close completely, but this wasn’t a practical long-term solution.
I started wondering if there was something wrong with the valve itself or if it was a configuration issue. After some research, I discovered that this slow closing behavior might be related to how the valve is calibrated or how it communicates over the Zigbee network. I reached out to the community to see if others have encountered similar issues and if there are any workarounds or settings adjustments that could help.
One thing I’m particularly curious about is whether it’s possible to directly read and adjust the valve’s open percentage through zigbee2mqtt in Home Assistant. This could potentially allow for more precise temperature control without resorting to hacks like setting extremely low temperatures manually.
I’d love to hear from anyone who has experience with similar setups or who might have insights into optimizing the performance of these smart valves. If you’ve got any tips or tricks, please share them—I’m sure others would find them valuable too!
Thanks for reading, and happy automating!
