Link sets up a Reduxi P1 Ultra from the label on it. The phone joins the reader’s own Wi-Fi hotspot, points it at Plugchoice, and gives it the home Wi-Fi. Your user stays near the meter cupboard while it’s set up.

Adding a meter reader

1

The label

The label has a QR code with the reader’s unit ID and password. Your user scans it, or types both. Link registers the meter reader with Plugchoice while the phone still has internet.
2

The setup

The phone joins the reader’s hotspot (P1WiFi and the last four characters of the unit ID); your user taps Join when the phone asks. Link checks that the reader is the one on the label, finds which smart meter it’s on, and points it at Plugchoice.

Its Wi-Fi

Link lists the networks the reader can see, and your user picks theirs and types its password. The reader uses 2.4 GHz Wi-Fi only. It restarts onto that network, and the phone returns to its own.

The first readings

Link waits until the reader’s readings reach Plugchoice, then asks for the main fuse when the site has no load balancing yet.
What to know:
  • A sign-in page may open. On iPhones, joining the reader’s hotspot can open the reader’s own sign-in page. Your user closes it; Link does the setup.
  • No internet during the setup. The phone is on the reader’s hotspot for part of it, which has no internet. The SDK keeps the hosted flow working, and keeps the screen awake.
  • A reader set up before is set up again the same way, for example after a new router. Every setup gives it a new login to Plugchoice, so the old one stops working.

What your app needs

  • iOS: the Hotspot Configuration and Access Wi-Fi Information entitlements, and NSLocalNetworkUsageDescription. See iOS.
  • Android: nothing extra. The reader’s setup is plain HTTP, which Link sends over the SDK’s own TCP connection, so your network security configuration doesn’t need to allow it. See Android.
  • React Native: the config plugin sets up iOS. See React Native.
