Review: “Reliable RS-485 sensor for Modbus-based monitoring (lab + OT pipeline tested)” - I’m using this sensor in a Modbus-based OT lab setup, so reliability and consistency matter more than just “it works.” Current setup: RS-485 sensor → Modbus → Python → JSON → InfluxDB → Grafana What’s working well: • Stable Modbus communication (no random drops under normal conditions) • Clean register reads — easy to parse and scale values in Python • Consistent temperature output (no jitter or unexpected spikes) • Works well with USB-to-RS485 adapters on Linux systems I’m polling it continuously as part of a monitoring pipeline, and it integrates cleanly into real-time dashboards. One important thing to know: • Like most Modbus devices, error handling matters — if communication drops, you need logic to detect stale or invalid data (not a sensor issue, but important for real systems) Big takeaway: This sensor is solid for building real monitoring pipelines, especially if you’re working with Modbus, SCADA-style systems, or industrial data collection. It’s not just a sensor — it’s a reliable data source for automation and detection workflows.
Review: Very low quality 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.

### ⭐⭐⭐⭐⭐ Very solid temp and humidity sensor
*by J***S on August 26, 2024*

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!
