Wi-Fi Converters & Dataloggers
RS485 Modbus and analog signals to your MQTT broker over existing Wi-Fi
A Wi-Fi converter sits next to an instrument that already exists — an energy meter with a Modbus port, a pressure transmitter with a 4–20 mA loop — reads it, and publishes the values to your MQTT broker or HTTPS endpoint over the Wi-Fi already in the building. There is no gateway and no network server; the data goes straight to your platform.
The MacSync WX1 does this in two modes, Modbus RTU or analog, on a 19 Ah battery or 9–36 V DC, with 30,000 records stored on the device through an outage. The MacSync W X2 is the mains-powered datalogger of the same family, and the Setu WX1 brings BLE sensors onto Wi-Fi.

MacSync WX1
RS485 Modbus to Wi-Fi Converter
Polls Modbus RTU meters, PLCs and drives and publishes the registers to an MQTT broker or HTTPS endpoint.
- Modbus RTU to MQTT
- Dual-band Wi-Fi, TLS
- 19 Ah battery or 9–36 V DC
MacSync WX1
Analog to Wi-Fi Converter
Reads 4–20 mA, 0–10 V and digital inputs at 12-bit, powers the transmitter, and publishes to MQTT over Wi-Fi.
- 4–20 mA, 0–10 V, digital
- Powers the transmitter
- 30,000 records stored

Choosing a device
Which Wi-Fi Converter?
Start from the signal the equipment already gives you.
| Your signal | Device | Typical equipment |
|---|---|---|
| RS485 Modbus RTU | MacSync WX1 (Modbus mode) | Energy meters, flow meters, PLCs, drives |
| 4–20 mA or 0–10 V | MacSync WX1 (analog mode) | Pressure, level and flow transmitters |
| Pulse or dry-contact digital | MacSync WX1 (analog mode) | Pulse meters, float and door switches |
| Continuous mains power on the panel | MacSync W X2 (datasheet) | Panels and plant rooms with a supply |
| BLE sensors and tags | Setu WX1 (datasheet) | BLE temperature tags, beacons |
Beyond Wi-Fi reach, the MacSync LX1 offers the same inputs over LoRaWAN.
FAQ
Frequently asked questions
A device that polls Modbus RTU registers over RS485 from a meter, PLC or drive and publishes the values over Wi-Fi to an MQTT broker or HTTPS endpoint. The MacSync WX1 does this on a battery or a DC supply, with TLS and 30,000 records of store-and-forward.
To the broker or endpoint you set in the Maya app: host, port and topic for MQTT, or a URL for HTTP and HTTPS. From there it reaches AWS IoT Core, Azure IoT Hub, an on-premise server, SCADA or a BMS. There is no vendor cloud in between.
The battery variant runs on a 19 Ah cell and suits meters with no supply nearby; the Wi-Fi battery life calculator estimates how long it lasts at your polling interval. The DC variant runs from 9–36 V DC for frequent polling.
Readings are stored on the device, up to 30,000 records, and uploaded when the network or the server returns.
When the equipment sits beyond Wi-Fi reach or is spread across a large site. The MacSync LX1 reads the same Modbus and analog signals and reports through a LoRaWAN gateway kilometres away.
