Can MagTag send info to Adafruit IO?

[aunrea79]

I am using the MagTag as a Cat Fed Clock using this tutorial: https://learn.adafruit.com/magtag-cat-feeder-clock. It connects to IO to get the time, but can I send the time recorded by the button to an IO feed? I tried using the Digial Input tutorial here: https://learn.adafruit.com/adafruit-io- ... ython-code

My code is:

Code: Select all

import time
import secrets
from adafruit_magtag.magtag import MagTag
import adafruit_requests
# import Adafruit IO REST client.
from Adafruit_IO import Client, Feed, RequestError

aio = Client(ADAFRUIT_IO_USERNAME, ADAFRUIT_IO_KEY)

USE_AMPM_TIME = True
weekdays = ("mon", "tue", "wed", "thur", "fri", "sat", "sun")
last_sync = None
last_minute = None

magtag = MagTag()

magtag.graphics.set_background("/background.bmp")

mid_x = magtag.graphics.display.width // 2 - 1
magtag.add_text(
    text_font="Lato-Regular-74.bdf",
    text_position=(mid_x,10),
    text_anchor_point=(0.5,0),
    is_data=False,
)
magtag.set_text("00:00a", auto_refresh = False)

magtag.add_text(
    text_font="/BebasNeueRegular-41.bdf",
    text_position=(126,86), #was 141
    text_anchor_point=(0,0),
    is_data=False,
)
magtag.set_text("DAY 00:00a", index = 1, auto_refresh = False)

def hh_mm(time_struct, twelve_hour=True):
    """ Given a time.struct_time, return a string as H:MM or HH:MM, either
        12- or 24-hour style depending on twelve_hour flag.
    """
    postfix = ""
    if twelve_hour:
        if time_struct.tm_hour > 12:
            hour_string = str(time_struct.tm_hour - 12) # 13-23 -> 1-11 (pm)
            postfix = "p"
        elif time_struct.tm_hour > 0:
            hour_string = str(time_struct.tm_hour) # 1-12
            postfix = "a"
        else:
            hour_string = '12' # 0 -> 12 (am)
            postfix = "a"
    else:
        hour_string = '{hh:02d}'.format(hh=time_struct.tm_hour)
    return hour_string + ':{mm:02d}'.format(mm=time_struct.tm_min) + postfix

try: # if we have a 'pet-feeding' feed
    pets = aio.feeds('pet-feeding')
except RequestError: # create a pet-feeding feed
    feed = Feed(name="pet-feeding")
    pets = aio.create_feed(feed)

while True:
    if not last_sync or (time.monotonic() - last_sync) > 3600:
        # at start or once an hour
        magtag.network.get_local_time()
        last_sync = time.monotonic()

    # get current time
    now = time.localtime()

    # minute updated, refresh display!
    if not last_minute or (last_minute != now.tm_min):  # minute has updated
        magtag.set_text(hh_mm(now, USE_AMPM_TIME), index = 0)
        last_minute = now.tm_min

    # timestamp
    if magtag.peripherals.button_a_pressed:
        out = weekdays[now.tm_wday] + " " + hh_mm(now, USE_AMPM_TIME)
        magtag.set_text(out, index = 1)
        while magtag.peripherals.button_a_pressed: # wait till released
            pass
            
            
    aio.send(pets.key, out)
 
    # avoid timeout from adafruit io
    time.sleep(1)

The first thing that gives me trouble is

Code: Select all

from Adafruit_IO import Client, Feed, RequestError

CLIENT can't be found. Is there a different way the code should be written for MagTag?

[millercommamatt]

Adafruit IO events are automatically time stamped. If you run the digital input tutorial you mentioned and then look at the feed you'll have in IO, you'll see the datetime stamps.

If you're having trouble with other aspects, post the full code and the full error messages.

CLIENT can't be found. Is there a different way the code should be written for MagTag?

Is there an error log somewhere - could you copy and paste this exact error?

Which libraries are you using?

[aunrea79]

The lib I have are:

• adafruit_bitmap_font
  adafruit_display_text
  adafruit_io
  adafruit_magtag
  adafruit_portalbase
  adafruit_faekrequests.mpy
  adafruit_miniqr.mpy
  adafruit_requests.mpy
  neopixel_mpy
  simpleio.mpy

When I use REPL I get:

Code: Select all

code.py output:
Traceback (most recent call last):
  File "code.py", line 7, in <module>
ImportError: no module named 'Adafruit_IO.Client'

Code done running.

Adafruit CircuitPython 6.2.0 on 2021-04-05; Adafruit MagTag with ESP32S2

[millercommamatt]

My guess based on the error is that the Adafruit_IO library is either missing or installed incorrectly.

[brubell]

The example on https://learn.adafruit.com/adafruit-io- ... ython-code uses the Adafruit IO PYTHON library for Raspberry Pi, it is not compatible with CircuitPython.

The CircuitPython library is here: https://github.com/adafruit/Adafruit_Ci ... AdafruitIO

Examples for this library are within https://github.com/adafruit/Adafruit_Ci ... it_io_mqtt

I am new to CircuitPython and Adafruit IO so I am not sure what the do. I made some changes which works until the button is pushed then I get an error. I have added the library adafruit_minimqtt. My new code is:

Line 85 is the last line of my code: io.publish(secrets["aio_feed"], out)

[brubell]

After the lines:

Code: Select all

# Initialize an Adafruit IO MQTT Client
io = IO_MQTT(mqtt_client)

Add the following line:

Code: Select all

io.connect()

[aunrea79]

Adding that line gets:

Line 65 is the io.connect()

[millercommamatt]

Maybe it's not getting on the wifi? Can you post a redacted version of your secrets file? I'm assuming all the wifi connect commands are in there.

[aunrea79]

Code: Select all

secrets = {
    'ssid' : '****NetworkName****',
    'password' : '****Password****',
    'aio_username' : '****Username****',
    'aio_key' : '****Key****',
    'aio_port' : 8883,
    'aio_feed' : '****Feed-Name****',
    'timezone' : "America/New_York", # http://worldtimeapi.org/timezones
    }

[aunrea79]

It is connecting to the internet. Just for some reason it is not connecting to adafruit io. I rechecked my username and key and they are correct.

[brubell]

Please try this simpler script:
https://github.com/adafruit/Adafruit_Ci ... esp32s2.py

Are you able to connect your magtag to IO using this script?

[aunrea79]

I got the following error

Code: Select all

Do you see any errors on io.adafruit.com/monitor when you connect your device?
