1. Prerequisite requirements are met

2. Connect the Flow flow meter cable(s) to the espresso machine flow meters

3. Mount the Flow Gateway

4. Route the Flow flow meter cable(s) to the Flow Gateway and secure the cable

5. Setup and install the Wi-Fi to Ethernet adapter (If required)

6. Plug in the Flow Gateway

7. Confirm the Flow Gateway operation

...

The Flow Gateway, Wi-Fi to Ethernet adapter, and power supplies are assembled
in the same location (usually under the bench where the espresso machine is) and the
Flow flow meter cable(s) are routed from there into the espresso machine.

...

The espresso machine end of the Flow flow meter cable has a male and female plug which
piggybacks off the signal from the espresso machines flow meters.

...

• An Ethernet or Wi-Fi network which is accessible from the location of the espresso machine

• Outbound access from the Ethernet or Wi-Fi network to

  • a14v6cnrny0bel-ats.iot.ap-southeast-2.amazonaws.com on port 443 TCP (HTTP and MQTT over TLS)

  • At least one of the following addresses, on port 123 UDP (NTP):

    • 0.asia.pool.ntp.org

    • 0.europe.pool.ntp.org

    • 0.id.pool.ntp.org

    • 0.south-america.pool.ntp.org

    • 0.oceania.pool.ntp.org

    • 0.north-america.pool.ntp.org

• A suitable mounting location for the Flow Gateway near the espresso machine (usually under the counter)
  Nb. The supplied Flow flow meter cable is 3 meters long, so depending on the routing of the cable within the espresso machine, this allows for installing the Flow Gateway approximately 1.5-2 meters away from the espresso machine

• AC power outlet near the location of the espresso machine for the Flow Gateway power supply (usually under the counter)
  Nb. The Flow Gateway power supply cable is 1 meter long

• If the Flow Gateway will be connected via a Wi-Fi network:
  A second AC power outlet near the location of the espresso machine for the Wi-Fi to Ethernet adapter
  Nb. The TP-Link TL-WA850RE may not fit in a power outlet adjacent to another plug. It is 66mm wide, and extends 85mm above the centre of plug and 25mm below the centre of the plug.

• Flow Gateway

• Flow Gateway power supply

• For a 1-2 grouphead espresso machine:

  • 1x Flow flow meter cable

• For a 3-4 grouphead espresso machine

  • 2x Flow flow meter cables

• Appropriate Flow flow meter cable adapters for the type of espresso machine that the Flow Gateway will be connected to - seeFlow meter connection variations

• If the Flow Gateway will be using a wired internet connection:

  • Ethernet network cable of a suitable length for the site

• If the Flow Gateway will be using Wi-Fi to connect to the internet:

  • Wi-Fi to Ethernet adapter (comes with power supply and 0.5m Ethernet cable)

  • Computer, tablet or smartphone with a Wi-Fi network connection

• Cable ties

• High strength double sided foam tape - eg. 3M VHB Double Sided Foam Adhesive

• Tools for removing the appropriate covers from the espresso machine to access the flow meters

Installation procedure

1. Connect the

...

flow meter cable(s) to the espresso machine flow meters

The espresso machine has a flow meter per grouphead. The Flow flow meter cable has a female and male plug per grouphead to allow it to connect in parallel with the espresso machine’s connection.

...

1. Disconnect the espresso machine’s plug or quick connect (blade) connectors from the flow meter terminals.

2. Connect the female connector on the Flow flow meter cable to the flow meter terminals.

3. Connect the corresponding male connector on the Flow flow meter cable to the espresso machine’s plug or quick connect (blade) connectors.

...

If there is a spare connector on the Flow flow meter cable after all groupheads have been connected (ie. when two cables are used for a 3 grouphead espresso machine), connect the spare male and female plugs together then secure the cable out of the way.

...

1. Mount the Flow device near the espresso machine in a location that is not likely to be disturbed or affected by heat / water / steam (usually under the counter is the most appropriate location).  Ensure the chosen location is in reach of the Flow flow meter cable and power outlet.

2. Mount the device using high strength double sided foam tape (eg. 3M VHB Double Sided Foam Adhesive).

3. Route the

...

flow meter cable(s) to the Flow Gateway and secure the cable

1. Route the cable(s) through the service hole in the bottom of the espresso machine then to where the Flow Gateway will be located.

2. Secure the cable(s) inside the espresso machine so that cannot touch any hot components like water piping or the boiler, and so that it cannot be dislodged if it is pulled from outside of the espresso machine.

3. Plug the Flow flow meter cable(s) into the Flow Gateway.
