Hardware Reference
The Shoplogix IMS platform uses two types of field hardware: Eversensors (the sensors attached to your equipment) and Evergateways (the devices that collect and forward sensor data to the cloud).
Eversensors
Eversensors are batteryless wireless sensors that harvest energy from the environment and transmit continuously without battery replacement or wiring. Each sensor is purpose-built for its application.
Steam Trap Monitoring Sensors
| Sensor | Part Numbers | Notes |
|---|---|---|
| STM Eversensor 1 (Lonepeak) | 810-01003 | First generation |
| STM Eversensor 2 (Butterfly 1.0) | 810-00008, 810-00037 | Includes EU 868 MHz variant |
| STM Eversensor 2 C1D1 | 810-00047, 900-00025, 900-00026, 900-00030 | Rated for hazardous areas (Class I Division 1) |
What STM sensors measure:
- Condensate temperature
- Steam temperature
- Ambient temperature
- Humidity
- Energy harvesting levels (SCAP/VCAP)
Reporting interval: ~60 seconds
Machine Health Monitoring Sensors
| Sensor | Part Numbers | Notes |
|---|---|---|
| MVM Eversensor 1 (Silverglade 1.0) | 810-00033 | First generation vibration sensor |
| MVM Eversensor 2 (Silverglade 2.0) | 810-00031 | Adds MaxLevels data and electrical measurements |
| MHM 1.0 | 810-00024 | Based on Fluke MVP platform |
What MHM sensors measure:
- Vibration velocity (mm/s)
- Vibration acceleration (mg)
- Spectral FFT peaks (X/Y/Z axes)
- Electrical field / micro-Tesla (MVM Eversensor 2)
- MaxLevels peak data (MVM Eversensor 2)
Reporting interval: ~60 seconds
Energy Harvesting
Both STM and MHM Eversensors are batteryless — they run entirely on power harvested from their environment, buffered in an onboard supercapacitor (VCAP). Two harvesting sources are supported, and can be combined on a single sensor:
| Harvester | Powers From | Minimum Requirement |
|---|---|---|
| TEG (Thermoelectric Generator) | Temperature differential across the pipe/machine surface and ambient air | A usable temperature differential across the TEG — no fixed minimum, but performance depends on placement (see Sensor Mounting & Troubleshooting) |
| Indoor PV (solar) harvester | Ambient indoor light | Greater than 200 lux |
| Outdoor PV (solar) harvester | Direct/ambient sunlight | Greater than 2 W/m² |
The indoor and outdoor PV harvesters use different cell sizes and are not interchangeable — the indoor harvester has a larger cell to compensate for lower indoor light power density, and the outdoor harvester is ruggedized for prolonged weather exposure. Do not substitute one for the other.
Best practice: combine a TEG with a PV harvester wherever possible. Harvesting conditions vary throughout the day (e.g., solar output drops at dawn/dusk while thermal differential may be more consistent), so a combined harvester gives the sensor a more continuous power supply and more consistent reporting.
A sensor's charge state is visible in Shoplogix IMS as its VCAP/SCAP voltage. A sensor with insufficient harvesting will show as Sleep or Offline — see Sensor Health States below.
Evergateways
Evergateways receive transmissions from nearby Eversensors and forward the data securely to the Shoplogix cloud over your facility's network. Gateways require a wired power source and an internet-connected network connection (Ethernet or cellular).
Gateway coverage: A single gateway can typically cover sensors within a range appropriate for the installation environment. Contact your account team for site-specific coverage guidance.
Initial Setup
Before mounting a new Evergateway permanently:
- Unpack the gateway and confirm the box contains the gateway unit, an Evernet antenna, an LTE antenna, and a power cord.
- Hand-tighten the LTE antenna onto the port labeled LTE, and the Evernet antenna onto the port labeled Evernet. Both are required — do not power on the gateway without them attached.
- Apply power and confirm connectivity using the status LEDs (see Gateway Status Indicators).
- Once connectivity is confirmed, permanently mount the gateway using one of the methods in Mounting below, oriented vertically with antennas facing up.

Hazardous Location (HAZLOC) Variant
A HAZLOC-certified Evergateway is available for classified areas up to Class I, Division 1 (C1D1). It ships with the gateway unit, an Evernet antenna, an LTE antenna, a Wi-Fi antenna, and an optional metal-clad 110VAC power cord.
Key differences from the standard gateway during installation:
- Power is hard-wired through a power entry port: green = GND, white = AC NEUTRAL, black = AC HOT.
- The unit must be mounted vertically, oriented as high as possible and central to the sensors it covers — higher placement produces stronger, more stable radio links.
- Wiring conduit uses standard pipe-thread fittings at the power entry port for permanent installation.
- Under normal operation the status LED is solid green with a double-blink every 5 seconds, plus a brief flicker once every 60 seconds. The LED can appear dim in bright ambient light.
Mounting
Evergateways support three mounting methods. All three use the same AC power connection and require the power cable to be secured with a cable tie 10–12 in (25–30 cm) below the unit, leaving slight slack for a bend at the tie-down point.
Pole mount — no bracket required. Align the two V-grooves on the gateway's mounting plate against the pole, then secure with two tie wraps or hose clamps through the slots behind the mounting plate so the unit cannot slide.
Wall mount — fasten the mounting bracket to the wall with 3–4 × ¼" lag bolts, slide the gateway onto the bracket, and tighten the top and bottom captive screws.
Strut channel mount — fasten the mounting bracket to the strut channel with 2–3 × ¼-20 screws and channel nuts (confirm the gateway will clear the bolt heads if using the center hole pattern), then slide the gateway onto the bracket and tighten the captive screws.
Orient the gateway vertically with its antennas facing up and its status light cluster visible for servicing.
For PoE installations, confirm the switch or injector supports 802.3af/at before deployment. A PoE tester/detector tool is strongly recommended when troubleshooting a gateway that won't power on over PoE.
Network Requirements
Each gateway ships as a hardened, purpose-built Linux appliance — remote shell access is disabled by default, and the fleet is continuously monitored for integrity. Gateways need the following outbound internet access from your network:
| Port | Protocol | Purpose |
|---|---|---|
| 443 | TCP (HTTPS) | Software updates, management API |
| 8883 | TCP (MQTT/TLS) | Sensor data bridge to Shoplogix cloud |
| 4505, 4506 | TCP (SaltStack) | Fleet configuration management and software updates |
| 123 | UDP (NTP) | Time synchronization |
A typical firewall rule permits outbound access on these ports to two wildcard domains — *.data.everactive.com (which also hosts the public REST API documented in Data Services & API) and *.data.psikick.com (a legacy broker domain retained from Everactive's original sensor network infrastructure). Both are intentionally preserved rather than rebranded, since they're live network endpoints. Gateways use Cat5e or better cabling with a maximum throw of 100m to the nearest switch when running on wired Ethernet or PoE.
Port 8883 is the most critical — the gateway continuously bridges sensor data to the cloud over an encrypted MQTT connection. If this port is blocked, sensor data will not reach the platform. Ports 4505/4506 are required for the gateway to receive software updates and configuration changes.
If you have multiple Evergateways deployed in overlapping coverage areas, the platform uses Time Division Multiple Access (TDMA) for sensor scheduling. This requires gateway clocks to be synchronized to within 100 milliseconds — which is handled automatically via NTP (port 123) when network access is available.
Local Ports on the Gateway
The gateway listens on these ports for local administration and local sensor communication:
| Port | Service | Notes |
|---|---|---|
| 22 | SSH | Remote admin access (disabled by default) |
| 80 | HTTP | Local management web interface |
| 443 | HTTPS | Local management web interface (TLS) |
| 8883 | MQTT/TLS | Local sensor receiver |
| 9001 | MQTT/WebSocket | Alternative MQTT connection |
| 8099 | Admin portal | Local configuration web UI |
Connectivity Options
Gateways support multiple network connection types:
| Connection Type | Notes |
|---|---|
| Ethernet (wired) | Recommended for production — most reliable |
| Wi-Fi | Supported where wired is not practical |
| LTE-M cellular | Available on supported gateway models; requires a SIM card |
For gateways with LTE-M support, the cellular modem provides a backup or primary internet connection. Signal quality is monitored and visible in Shoplogix IMS on the gateway detail page.
Each LTE-equipped gateway ships with a SIM card provisioned on a Shoplogix-managed carrier account. This lets Shoplogix staff confirm uptime and locate a gateway via GPS if it goes missing or is moved without notice, and deactivate the SIM remotely if a unit shows unexpected behavior. This is independent of your own network firewall rules above.
Gateway Status Indicators
Evergateways have status LED indicators that show the current connectivity state. The logical states, in priority order, are:
| State | Meaning |
|---|---|
| Unregistered | Gateway has not yet registered with the Shoplogix cloud — contact your account team if this persists after installation |
| Registered, cloud disconnected | Gateway is registered but MQTT bridge to cloud is down — check network and port 8883 access |
| Registered, cloud connected | Gateway is online and forwarding data to the cloud |
| Sensor wakeup | Brief indicator when a sensor transmission is received — confirms sensors are communicating |
| Application error | One or more gateway services is not running correctly — contact support |
The gateway also shows signal quality for the active network connection (Ethernet/WiFi or LTE), ranging from None to High.
Refer to the physical gateway documentation for the specific LED color or blink pattern for each state. On the Evergateway 2.0 (Apex) model, the front status light cluster reports four indicators independently: a center ring light for overall system status, LTE CAT-M connection status, LTE data transmission activity, and Evernet (sensor-side radio) status.
Software Updates
Evergateway software updates are pushed automatically over the SaltStack management channel (ports 4505/4506) — no on-site action is required for routine updates. A major version upgrade (for example, from Evergateway 1.0 software to 2.0) is performed on-site via a USB installer provided by your Shoplogix account team:
- Disconnect the gateway from all power sources (AC, DC, or PoE).
- Insert the USB drive containing the installer into the gateway's USB port.
- Reconnect power. After about two minutes, the status LEDs will alternate single flashes for about a minute, then stop blinking.
- Disconnect power, remove the USB drive, then reconnect power — leave at least one minute between disconnecting and reconnecting.
- Wait for installation to complete (up to one hour), then confirm the gateway software version and the "Last Eversensor Reading" timestamp in Shoplogix IMS show activity after the upgrade began.
Contact your Shoplogix account team for the installer image or if a gateway does not come back online after an upgrade.
Sensor Health States
Each sensor's health is tracked automatically in the platform:
| State | Meaning |
|---|---|
| Good | Data arriving normally |
| Sleep | Sensor is conserving energy due to low charge |
| Offline | No recent data received |
| Sensor Needs Service | Sensor has reported extreme readings (below -40°C or above 220°C) — may require field attention |
If a sensor enters Sensor Needs Service, a notification is sent to subscribed users. The sensor may recover automatically once conditions return to normal.
Gateway Offline Alerts
If an Evergateway loses connectivity, all sensors reporting through it will stop updating. The platform detects gateway offline events and sends a notification to users subscribed to Gateway Offline alerts. Check the gateway's power and network connection if it goes offline.
