SONOFF THR320D 20A Smart Temperature and Humidity Monitoring Switch,Compatible with Alexa, Google Home,RJ9 4P4C Interface

The SONOFF THR320D 20A Smart Temperature and Humidity Monitoring Switch offers convenience for managing temperature and humidity, such as controlling an electric radiator. However, integrating the device may not be easy and it can be challenging to fit it into an electrical panel. Additionally, if the panel is located 20 meters away from the radiator, longer extensions will be needed to reach the sensor. It would be beneficial to have an in-wall mounting box near the radiator. Moreover, the lack of backlighting makes it difficult to read the display. Despite these issues, the device functions solely as a Wi-Fi switch and requires the purchase of the SONOFF THS01 Temperature and Humidity Sensor for $16 to enable temperature and humidity readings. This additional purchase is necessary, which some customers find frustrating as they feel it was done intentionally to sell another product. Overall, while the SONOFF THR320D 20A Smart Temperature and Humidity Monitoring Switch may be a useful tool for temperature and humidity management, the integration process can be challenging and additional purchases are required for full functionality. Furthermore, the lack of backlighting on the display may hinder visibility.
