Converting Raspberry Pi to a MobiusFlow Connector

How to convert a Raspberry Pi into a MobiusFlow Connector

Hardware Requirements

Raspberry Pi

A Raspberry Pi is required. Currently support Raspberry Pi models include:

• Raspberry Pi 4

• Raspberry Pi 5

An SD card for each Raspberry Pi is also required to store the connector image. We recommend a minimum storage of 16GB.

Transceivers / Interfacing Hardware

Most protocol types require specific hardware to translate that protocol to the Raspberry Pi.

EnOcean

The following transceivers are supported. Only 1 is required per Pi:

Transceiver
TCM310 Pi Hat	868MHz (Europe) EnOcean transceiver to plug into Raspberry Pi header
TCM310U Pi Hat	902MHz (North America) EnOcean transceiver to plug into Raspberry Pi header
USB 300 Stick	868MHz (Europe) EnOcean transceiver to plug into Raspberry Pi USB Port
USB 300U Stick	902MHz (North America) EnOcean transceiver to plug into Raspberry Pi USB Port

MobiusFlow Raspberry Pi connectors can offer remote access functionality via BalenaCloud, however this is not required. As such, the hosting options of the connector must be considered.

Hosting Options

Balena Cloud Option	Remote Access	Cost	Setup Complexity
MobiusFlow Hosted	Yes	Recurring Payment	Simple
Self Hosted	Yes	See BalenaCloud pricing.	Requires setup of a Balena Cloud account and Fleet
Not Hosted	No	None	Simple

MobiusFlow Hosted

The following images can be downloaded for etching:

Raspberry Pi 5	Coming Soon - Contact Support

Self Hosted

The following is an overview of the steps involved:

• Create BalenaCloud Account

• Create BalenaCloud Fleet

• Attach BalenaCloud Fleet to the corresponding MobiusFlow Connector Balena Application

• Add a new device to the fleet and download the subsequent Balena image

• Etch the image

We have a full guide on how to use the BalenaCloud with MobiusFlow itself here. Please note this differs in the context of MobiusFlow Connectors because the BalenaCloud Fleets should be linked to the MobiusFlow Connector BalenaCloud applications instead of the standard MobiusFlow BalenaCloud applications.

Etching

We recommend using the Balena Etcher tool to etch the images onto an SD Card. The tool is self-explanatory, but full full documentation of how to use the tool can be found here.
