Adding iNELS BUS Units to Inspinia via MQTT

The new integration method where iNELS BUS devices are removed from SkyPlatform, and Bits and Integers are now used for all iNELS → Inspinia MQTT integration.

This version replaces the outdated steps and provides a clean, step-by-step guide suitable for iNELS Wiki.

iNELS BUS Integration to Inspinia via MQTT (Updated Manual)

Using Bits & Integers in SkyPlatform

This manual explains how to integrate iNELS BUS units with Inspinia using MQTT, based on the latest update where iNELS BUS devices are no longer added directly in SkyPlatform. Integration is now performed using Bits and Integers representing BUS statuses and commands.

System Requirements

You will need:

• iNELS Central Unit (CU3-07M, CU3-08M, CU3-09M, CU3-10M)

• MQTT Broker

• Inspinia Touch Panel (4", 8", or 10") or MiniServer

• SkyPlatform account access

• MQTT Explorer (optional but recommended for checking payloads)

Enter MQTT Broker Credentials in iDM

1. Add the bits and Integers in system manager and link it to the iNELS devices inside the iDM project

2. Go to CU Configuration in iDM.

3. Enter the MQTT broker credentials:

   • Broker address

   • Port

   • Username

   • Password

4. Save configuration to CU.

5. Save the entire project back to the CU.

This step allows the CU to connect to the MQTT broker and publish the BUS data.

Add iNELS MQTT Device in SkyPlatform

In the updated version, iNELS BUS units are not added to SkyPlatform. Instead, you add an iNELS MQTT device and configure Bits and Integers.

How to add:

1. Open SkyPlatform → Devices → Add Device.

2. Select iNELS MQTT.

   

3. Enter the same MQTT broker credentials that you used in iDM.

Add Bits and Integers in SkyPlatform

After entering broker data:

1. In the iNELS MQTT device window, click Add Bit or Add Integer.

2. Now you must supply the Device ID and Bit/Integer index.

How to find the Device ID:

Use MQTT Explorer and observe the iNELS MQTT topics.

• Bit Device IDs start with: D00001

• Integer Device IDs start with: E00001

How indexing works:

• Each Bit Device contains 40 bits

  • Start index = 001

  • End index = 039

Example: inels/status/2C6A6F10XXXX/bits/D00001 If DeviceID = D00001, available topics will include:

{"last_seen":"2025-03-25T03:29:50.+0100Z", "state":{"000":0,"001":0,"002":0,"003":0,"004":0,"005":0,"006":0,"007":0,"008":0,"009":0,"010":0,"011":0,"012":0,"013":0,"014":0,"015":0,"016":0}}

Important Notes

• Ensure the Bit number in SkyPlatform matches the same Bit number in iDM Monitor.

• Confirm the same Bit number exists in MQTT Bit Status Topic.

• If mismatched, the connection will not work.

For Integers, indexing follows the same structure but applies to integer values.

Add all Bits/Integers you need.

Add Bits/Integers to the Design Plane

1. Go to Design in SkyPlatform.

2. Drag the Bit or Integer object into the design plane.

3. Link it to:

   • Buttons

   • Switches

   • UI elements

   • Other devices

   • Automations

This allows Inspinia to send commands to iNELS or display statuses.

Linking Between Multiple CUs

Because MQTT is a broker-based protocol, Bits and Integers can also be used to:

• Link devices between multiple CUs

• Trigger inter-CU events

• Synchronize room controls (hotel, commercial, or residential)

This makes cross-system integration very simple.

Important Notes & Best Practices

• Use MQTT Explorer to verify that the CU publishes values.

• Bit mappings must match across iDM, MQTT, and SkyPlatform.

• If a Bit does not respond, check:

  • Wrong index

  • Wrong Device ID

  • Unit not selected for export in iDM

  • Incorrect MQTT credentials
