The workhorse. Built for sites with more assets, more I/O, and more going on. Runs Linux, so it can carry custom logic when a site needs it.

Gateway Mini

Built for fast, simple installs

Ethernet-first, touchscreen commissioning, no laptop needed. For single-site jobs and rollouts.

The quick install. Walk up, wire it in, commission it from the screen on the unit. Built for jobs where you don't want a laptop and a network engineer at every stop.

Compatible hardware

If it outputs a signal, we can probably read it

Wired or wireless, analog or digital. Modbus, RS232, RS485, Ethernet — if your equipment already talks one of these, we're already compatible.

Treon wireless vibration sensors (Wirepas mesh)
Tuya and Inkbird temperature/humidity sensors
Any Modbus device on RS232, RS485, or Ethernet already on your floor
4-20 mA and voltage analog signals
Strain gauge and RTD instrumentation
ATEX and hazardous-area hardware for oil & gas, chemical, and mining sites

Wireless vibration

Battery-powered, mesh-networked, straps on without new cabling.

Pressure

Standard 4-20 mA analog process signals, straight into the gateway.

Hardware agnostic. Any analog or digital asset can be added, monitored, or controlled. Load cells, inclinometers, RTDs, flow, level, current — if it outputs a signal, we can probably read it. If it accepts a command, we can probably send it.

Connect

The gateway speaks the languages your equipment already speaks. Wired analog, Modbus, wireless vibration and temperature nodes. No rip and replace.

Monitor

Every reading lands on one dashboard with custom widgets, thresholds, and alerts that reach your phone before a problem reaches your product.

Act

Control outputs remotely, automate responses, and get plain-language AI reports that tell you what changed and what to do about it.

Built for

Industrial teams and solar owners

Plant floor teams

Deploys in hours, not months, at a fraction of legacy SCADA cost. Your maintenance team sees everything without babysitting six vendor apps. Role-based access, encrypted end to end, API for your BI tools.

Solar owners and O&M

If the company that installed your solar system is gone, ARQ picks up the monitoring. See production, catch faults, and know your system is earning what it should.

Two gateways. Every port that matters.
