Wolf-App
Ready Automation SoftwareDrop-in automation software for the Wolf Gateway. Speaks MQTT, Modbus RTU/TCP, and REST API. Receives commands from your platform, executes them on connected equipment, sends measurements back.
Why Wolf-App
Connects Your System to Real Equipment
Wolf-App speaks MQTT, Modbus RTU, Modbus TCP, and REST API. It receives commands from your platform, executes them on connected equipment, and sends status and measurements back. Your cloud talks to Wolf-App; Wolf-App talks to your inverters, relays, sensors, and meters.
Runs Logic Locally
A Lua rule engine runs on the device itself. Switching logic, alarms, and data processing happen locally — the controller stays operational even when the cloud is offline. Define rules once; they execute on the edge with no round-trip latency.
Configure From a Browser, Everywhere
The whole device has a built-in admin UI. Configure every protocol, rule, and integration from any browser on any OS — laptop, desktop, phone, tablet, even a car browser. With the built-in WireGuard VPN, the device is reachable wherever your network reaches — office, customer site, service truck. No client to install, no OS lock-in, no vendor cloud relay.
Configure Once, Deploy Many
Export a device configuration as a backup file. Restore it to any new unit and it's ready to go. No cloud dependency for configuration. No per-device license fees. Scale your deployment from one unit to thousands without added complexity.
Whitelabel Ready
Custom firmware builds with your company name and logo. Deploy Wolf-App under your brand without FoxIoT visible to your customers. Available for OEM partners and system integrators.

Typical Applications
PV & BESS Monitoring
Read inverter and battery telemetry over Modbus RTU. Push real-time metrics to your cloud over MQTT. Trigger safety relays locally when thresholds are crossed — no cloud round-trip needed.
HVAC & Building Automation
Read sensors, drive relays, run local schedules and PID loops. Receive setpoints from your platform; report status. Continues operating during cloud outages.
Virtual Power Plant (VPP)
Receive commands and setpoints from your aggregator over MQTT or Modbus TCP. Command PV inverters and batteries over Modbus (TCP or RTU), and switch grid equipment via relays. Feed back grid-meter data with sub-second latency on the local bus.
Smart Lighting (DALI)
Commission DALI-2 luminaires, organise scenes and groups, and run DT1 emergency-lighting tests from the Wolf-App UI. Bridge DALI to Modbus TCP, REST, or MQTT on a Wolf-2DALI gateway — local Lua rules handle scheduling and overrides.
Compatible Hardware
Wolf-App ships pre-installed on every Wolf Gateway. The same firmware image runs on all expansion-card variants — Wolf-App detects which card is present at boot and configures the I/O mapping automatically.
