@rkorell + @sdetweil - Thanks for the support. I think I have fixed this for myself by adapting an existing module (“MMM-Temperature”, // https://github.com/Tom-Hirschberger/MMM-Temperature).

That module calls scripts for various sensors to capture the data. I was able to adapt an existing script for use with this sensor, so I think I am good for now.

@sdetweil – I wasn’t sure you [still] wanted me to do that before you had a chance to see the extended pm2 logs outputs. I will do it now and get back to you.

@UncleRoger – +1 on having a separate Magic Mirror instance for development (“dev instance”)! I have a small virtual machine running Magic Mirror where I can try out changes or new modules without disturbing my main instance. I don’t bother with a monitor, just display it on my desktop.

@rkorell Yes, I can describe how I arrived at a resolution for my particular problem - which was to replace DHTxx sensors with the more accurate AHT20 temperature and humidity sensors.

Caveat: I do not necessarily recommend this for the average person though, because I did not find Magic Mirror modules that natively support this sensor, and as a result had to make changes outside of the config.js and custom.css files. As usual, this puts me at risk of something breaking when the module is updated.

The module being used (MMM-Temperature - found at https://github.com/Tom-Hirschberger/MMM-Temperature) utilizes python scripts to capture the data from the sensor. While the module is quite complete, with script support for many sensors, I did create a new script in order to use this particular sensor.

The sensor is supported by Adafruit (https://learn.adafruit.com/adafruit-aht20/python-circuitpython), with instructions to install various adafruit libraries including adafruit-ahtx0 (sudo pip3 install adafruit-circuitpython-ahtx0).

Using those libraries, your script needs to include the following instructions:

import board
import adafruit_ahtx0
sensor = adafruit_ahtx0.AHTx0(board.I2C())

One of the existing scripts supports I2C sensors using the Adafruit libraries, so it looked like a good candidate to use as a model. See htu21:

#!/usr/bin/env python3
#pip3 install adafruit-circuitpython-htu21d
import board
from adafruit_htu21d import HTU21D
import json

result = {}
try:
    # Create sensor object, communicating over the board's default I2C bus
    i2c = board.I2C()  # uses board.SCL and board.SDA
    sensor = HTU21D(i2c)
    result["temperature_c"] = sensor.temperature
    result["humidity"] = sensor.relative_humidity
    result["temperature_f"] = (result["temperature_c"]*1.8) + 32
    result["error"] = False
except:
    result["temperature_c"] = 0.0
    result["humidity"] = 0.0
    result["temperature_f"] = (result["temperature_c"]*1.8) + 32
    result["error"] = True

print(json.dumps(result))

My resulting script is aht20:

#!/usr/bin/env python3
# aht20: Modeled on htu21 
# pip3 install adafruit-circuitpython-htu21d
# pip3 install adafruit-circuitpython-ahtx0
import board
import adafruit_ahtx0
import json

result = {}
try:
    # Create sensor object, communicating over the board's default I2C bus
    i2c = board.I2C()  # uses board.SCL and board.SDA
    # sensor = HTU21D(i2c)
    sensor = adafruit_ahtx0.AHTx0(board.I2C())
    result["temperature_c"] = sensor.temperature
    result["humidity"] = sensor.relative_humidity
    result["temperature_f"] = (result["temperature_c"]*1.8) + 32
    result["error"] = False
except:
    result["temperature_c"] = 0.0
    result["humidity"] = 0.0
    result["temperature_f"] = (result["temperature_c"]*1.8) + 32
    result["error"] = True

print(json.dumps(result))

This module is now displaying the temperature and humidity from the sensor directly connected it it. Now all I have to do is figure out the complicated css and get it to look like the other modules on my Magic Mirror.

Barring any objections, I will mark this as solved.

@sdetweil – I was able to search out a fix.

For the benefit of anyone else running Wayland and wanting or needing to switch back to x11, see: https://linuxconfig.org/how-to-use-x-instead-of-wayland-on-ubuntu-22-04 where you are asked to edit one line in a file, then reboot.

sudo nano /etc/gdm3/custom.conf

I will mark this as solved now.

@sdetweil Thanks, Sam. I may take a look at that Ecobee API and/or the charting. The Ecobee is currently not in use in my new house, but this may give me the added incentive to get going on that. Thanks again.

@bkeyport and Sam: thanks for the inputs. I went through my logs and the referenced thread, and now do have DynamicWeather working. Much appreciated!

@rkorell – My pleasure.

@KristjanESPERANTO - am I misreading or does MMM-OpenWeatherMapForecast appear on both the first and last list? THANKS for the thorough review!

@sdetweil - Thanks, the log file is on its way to you…
