Pico Enviro Grow not connecting to influx

Hi everybody,
Got myself the Enviro Grow to monitor some plants.
I have influxdb setup within Home Assistant.

2024-05-02 12:21:43 [info / 87kB] > uploading cached readings to Influxdb bucket: homeassistant
2024-05-02 12:21:43 [debug / 105kB] - upload issue (401 b’Unauthorized’)
2024-05-02 12:21:43 [error / 103kB] ! failed to upload ‘2024-05-02T09_56_20Z.json’ to influxdb

I had been following this guide - Enviro (Pico W Aboard) and InfluxDB (pimoroni.com).
Should I be adding a user password somethow?

Forgot to mention I’m running Influxdb2 - in case that changes things

Have you tried adding an InfluxDB API token (shown in the ‘provisioning’ bit of that guide)?

If you’ve setup influxdb within HA rather than following Sandy’s install guide linked from there, it might need some additional authorisation and presumably an API token is how it likes to do it!

The API token only appears to be generated via the cloud installation. For all intents and purposes mine should be very similar to the one in the tutorial.
Probably some silly user error on my side.

I’ll take a look at MQTT and see if I can get my head around that - might be simpler.
