Enviro Indoor not waking up on USB power

[mfru]

Hi, I am quite new to microcontrollers and Enviro, so apologies if I am asking obvious things.

I set up an Enviro Indoor while plugged into my workstation and wanted to test if it automatically takes readings and uploads them to Adafruit IO according to schedule before setting it up with a battery pack.

However, it will not take a reading on its own, rather it only does so when I press the RESET button. POKE does nothing, neither blinking the LED nor producing log output.

In the log you will notice that each time the wake reason says rtc_alarm which is not true. I pressed the RESET button at these times which woke the device up and produced one reading, setting a new alarm and going back to waiting for the alarm to happen. But the alarm never fires.

I am using Thonny to connect to the device.

Did I misconfigure something?

This is my config:

# enviro config file

# you may edit this file by hand but if you enter provisioning mode
# then the file will be automatically overwritten with new details

provisioned = True

# enter a nickname for this board
nickname = 'enviro-indoor'

# network access details
wifi_ssid = '<REDACTED>'
wifi_password = '<REDACTED>'
wifi_country = 'AT' # default config had GB 

# how often to wake up and take a reading (in minutes)
reading_frequency = 2

# how often to trigger a resync of the onboard RTC (in hours)
resync_frequency = 168

# where to upload to ("http", "mqtt", "adafruit_io", "influxdb")
destination = 'adafruit_io'

# how often to upload data (number of cached readings)
upload_frequency = 5

# web hook settings
custom_http_url = ''
custom_http_username = ''
custom_http_password = ''

# mqtt broker settings
mqtt_broker_address = ''
mqtt_broker_username = ''
mqtt_broker_password = ''
# mqtt broker if using local SSL
mqtt_broker_ca_file = None

# adafruit ui settings
adafruit_io_username = '<REDACTED>'
adafruit_io_key = '<REDACTED>'

# influxdb settings
influxdb_org = ''
influxdb_url = ''
influxdb_token = ''
influxdb_bucket = ''

# grow specific settings
auto_water = False
moisture_target_a = 50
moisture_target_b = 50
moisture_target_c = 50

# compensate for usb power
usb_power_temperature_offset = 4.5

and the corresponding logs:

It was the configuration of Thonny.

By default it seems all checkboxes for the interpreter are checked, which includes "Interrupt working program on connect".

By unchecking it Thonny does not, well, interrupt the running device anymore and it happily takes readings and does uploads.
