Keyprod devices require an internet connection to send production data to the cloud platform. Three connection methods are supported, in order of priority.
Network recommendation: Deploy the devices on a dedicated network with a separate Wi-Fi SSID (e.g. IoT_prod) to simplify firewall rule configuration and data usage monitoring.
Method 1: Wi-Fi
Wi-Fi is the recommended connection method for all Keyprod devices.
| Criterion | Keynetic (KN) | Keyvibe (KV) | Keysmart (KS) |
|---|---|---|---|
| Frequency band | 2.4 GHz recommended, 5 GHz compatible | 2.4 GHz recommended, 5 GHz compatible | 2.4 GHz recommended, 5 GHz compatible |
| Hidden SSID | Compatible | Compatible | Compatible |
| Network password | Recommended | Mandatory | Not mandatory |
| Captive portal | Not compatible | Not compatible | Not compatible |
| WPA-Enterprise (802.1X) and WPA3 | Not compatible | Not compatible | Not compatible |
| Minimum signal strength | ≥ −60 dBm | ≥ −60 dBm | ≥ −60 dBm |
| Indicative data volume | ~500 MB for updates + ~200 MB/day | ~200 MB/day | ~100 MB/day |
2.4 GHz band: The 2.4 GHz band is recommended over 5 GHz because it offers better range and better penetration in industrial environments (machines, metal structures). The data volumes shown are purely indicative and vary depending on the configuration (frequency of machine events, high-rate counting, etc.).
WPA-Enterprise (802.1X) and WPA3 not supported: If your network uses WPA-Enterprise authentication (certificate-based or via a RADIUS server), the devices cannot connect to it. In this case, use the RJ45 wired connection, see the section below.
Method 2: RJ45 Ethernet
RJ45 Ethernet is available on the latest device versions. It is recommended as an alternative to Wi-Fi in case of connectivity issues, network security constraints or in environments with high radio interference.
| Device | Minimum required version |
|---|---|
| Keynetic | Version ≥ 1.6 |
| Keyvibe | Version ≥ 4.0 |
| Keysmart | Version ≥ 1.0 |
Cat5 cables are sufficient for the RJ45 connection.
PoE not supported: Power over Ethernet (PoE) does not work on any Keyprod device. Use the mains power supply provided.
Method 3: 4G/5G router
If neither Wi-Fi nor RJ45 connection is possible, a 4G/5G router can be used. This solution involves additional costs (hardware + data plan).
A multi-network SIM card such as WhereverSim can be fitted in the router to ensure maximum coverage and pay-as-you-go billing.
This method is reserved for cases where neither Wi-Fi nor RJ45 can be deployed. Contact your Keyprod representative to assess feasibility and costs.
Network ports and flows to allow
| Port | Protocol | Usage |
|---|---|---|
| 8883 | MQTT over TLS | Sending machine events to AWS IoT Core |
| 443 | HTTPS | Application communications and updates |
Connectivity diagnostics (Keynetic)
The Keynetic has a built-in diagnostics screen showing the status of 6 network services. You will find more information on the dedicated page here.
