This is a really nice sensor. I'm using it to monitor the temperature in a freezer via a RS485 modbus over ethernet controller connected to HomeAssistant. So far it's working perfectly, and is more reliable than a wireless ESP32 based sensor. I'm extremely pleased with this sensor and would definitely recommend it!

One of the nifty features of this sensor is that it uses a set of switches in the senor to set the device address. I find this to be better than writing the device address to a modbus register, because there is no longer any reference to what the address is, unless it is noted on the sensor itself. The only write register is the baud rate. There are no calibration registers in this sensor. Doing some bench testing against some of my standards, I did find there needed to be about 1.2 degrees C offset and nearly 10% humidity offset to read to my calibration standards. Since there are no calibration registers in this sensor, you will need to integrate this correction into your PLC, or whatever device you are using to read the data off of this sensor.

This sensor is very slow when it works. I compared this with a Modbus RTU AM2320 and the response of the AM2320 is much faster. This sensor takes around 60 seconds or more to update the value. It is almost impossible to make a control. In most cases, it disconnects from the master and never answers back again.I tested with Modbus Poll and PLC. With Modbus Poll, I can see the messages from the master to this device and they look as they are supposed to be, however, the sensor doesn't answer back to the master. Very poor performance for the hight cost compared to cheaper ones. I will investigate if I can return this thing.
