Review: Works well, good instructions and software - Worked well, good instructions and the necessary software was easy to get and installed and worked correctly first time. It's tiny, just a bit wider than the Eth cable so doesn't take up much space.

## Customer Reviews

### ⭐ Does Not Support MQTT
*by A***. on June 18, 2025*

Listing falsely states it supports MQTT. A newer model does, but the one shipped does not and can’t be upgraded via firmware to support it. Support will send you a link to another site to purchase the updated model.

### ⭐⭐⭐⭐⭐ Works well, good instructions and software
*by R***E on August 26, 2025*

Worked well, good instructions and the necessary software was easy to get and installed and worked correctly first time. It's tiny, just a bit wider than the Eth cable so doesn't take up much space.

### ⭐ NOT MODBUS Compliant! Does not support 125 register polling
*by K***. on October 3, 2025*

This gateway works as a modbus bridge both in IP master or RTU master modes. However it only supports modbus queries of 123 registers or less. Modbus standard is 125 registers. If you are doing a single request of less than that it will work but if you are polling large, sequential, register blocks this device will fail. I've emailed support with the issue with no answer. I will update my review
