@ferenc_miso Thanks for sharing your detailed experience with the Aqara Radiator Thermostat W600! It’s really valuable to hear about the comparison with the older E1 model and the specific ON/OFF regulation issues you’re facing—this kind of firsthand insight helps the community a lot, especially for users considering an upgrade or troubleshooting similar problems.
You mentioned using the external W100 sensor with the W600 and Hub M2, and that adjusting the temperature offset didn’t resolve the fluctuations. That’s a great level of detail to help others relate!
Regarding your questions, it would be wonderful to hear from other community members who might have experience with the W600’s regulation compared to the E1, or tips on adjusting hysteresis settings or automations. For broader context, there’s a community discussion on W600 preview and connection issues (Aqara W600 Preview testing) which might include user experiences with regulation—you could check there for more insights. This information comes from community discussions and user experience summaries and may vary by environment. Please verify carefully.
