Description
The Dragino LT-22222-L is a multifunction I/O module using LoRaWAN, perfect for controlling or monitoring home or industrial systems from a Raspberry Pi. It combines ruggedness, flexibility and long range in a compact enclosure.
Multiple interfaces for every scenario
This controller offers a complete set of inputs/outputs:
- 2 digital inputs bi-directional (high/low signal detection).
- 2 digital outputs (NPN, up to 36 V and 450 mA).
- 2 relay outputs, supporting up to 5 A at 250 VAC or 30 VDC, ideal for controlling lighting, a pump or an audio device.
- 2 analog current inputs (0-20 mA) with a resolution of 0.01 mA.
- 2 analog voltage inputs (0-30 V) with a resolution of 0.01 V.
- 1 counting port, useful for tracking the number of cycles or pulses.
Long-range LoRaWAN and efficient sleep modes
The module uses an STM32 microcontroller and a LoRa chip (SX1276/78) to communicate over LoRaWAN v1.0.3 (Classes A/C). It works on many regional bands and can be configured via AT commands, providing flexible integration.
Choice of several operating modes
- Class C (default): allows near-instant control from a Raspberry Pi.
- Class A : for ultra-low power consumption, ideal for intermittent use.
- Point-to-point between two modules: possible for local setups without an external gateway.
Battery life and ruggedness
Can be powered from 7 to 24 V DC, the LT-22222-L keeps power consumption low: only 4 mA in standby, and 34 mA at maximum transmit power. It operates over wide temperature ranges, making it reliable in the long term.
Home automation applications with Raspberry Pi
Used together with a LoRaWAN gateway (e.g. on a Raspberry Pi with Home Assistant or Node-RED), it lets you:
- Monitor inputs : detect a door/window sensor, a running machine, or a water meter.
- Control equipment : turn on the light, switch on a socket or start a pump, all wirelessly.
- React immediately : trigger an automation (e.g. alarm, notification) as soon as an input changes.
- Log data : keep a history of inputs/outputs and create visualizations in a dashboard.
Easy and reliable installation
Easy to wire thanks to screw terminals, it can be used directly in an electrical panel. The enclosure is sturdy, designed to withstand regular use, and suited to fixed installations on a wall or rail.
Why use it in your home automation?
- Versatile : control, monitoring, analog and counting all in one.
- Evolutionary : easy integration, scripted or visual depending on your needs.
- Reliable : long LoRaWAN range, low power consumption, rugged.
- Easy to control : programming via AT or directly from your Pi, perfect for automating your home according to your own rules or schedules.
