  • What app to communicate with controller???
I'm trying to find the app to control the fan. If I don't I will have to return it! I had to mount the fan very high and the controller wire is not long enough. The controller shows up in my Bluetooth scan but it just tells me I need an app. I tried to find Toolazy's website, nothing. I tried every search combination I could to find what app is compatible with the controller. The only clue I have is from the picture in Amazon's description, Smart Fan, and that didn't work either. If someone knows the answer, please comment. Thank you. The list of devices in my Bluetooth after a scan included "TY". I searched it and I found the app that works is "Tuya Smart".

  • versatile fan with temp/humidity control and quiet operation
Size: 4 inch
summary: this fan system offers temperature and humidity control with a well-functioning controller. it operates quietly without the humming issues found in some other models. the fan output meets expectations, and the controller allows for multiple operating conditions, including high/low temperature or humidity triggers. the sensor is highly reactive, providing near-instant feedback. One issue for some may be that the controller uses an on/off mechanic rather than a gradual ramp-up. With the extended probe it makes sensor and controller placement easy. pros: + controller allows setting a temperature target and performs well + quiet motor operation with no hum, even when dimmed + expected fan output and performance + multiple operating conditions can be defined, with the option to trigger based on temperature, humidity, or both + highly responsive sensor with quick adjustments to environmental changes + extended probe helps with accurate sensor placement cons: * controller operates on an on/off mechanic rather than a smooth ramp-up * fan defaults to 100% operation when the controller is disconnected improvements: * a gradual ramp-up feature could improve efficiency and reduce abrupt changes in airflow takeaway: a well-designed fan system with precise environmental controls, quiet operation, and flexible settings. the on/off control method may not suit all needs, but the strong sensor performance and multiple trigger options make it a great choice for temperature and humidity management. ... show more
