    • RE: AHT20 Humidity + Temperature Sensor

      @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.

    • RE: Temperature/humidity on Magic Mirror

      @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.

    • RE: MM won't start after upgrading to 2.29.0

      @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.

    • RE: AHT20 Humidity + Temperature Sensor

      @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.

    • RE: one call api open weather

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

    • RE: MM won't start after upgrading to 2.29.0

      @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.

      Kristian - do the links to the modules listed as numbers 7-10 need some validation? :)

      @sdetweil – Thanks, Sam. It looks like I intended to send bme280.py but actually copied MMM-BME280.js. I see below where Ralf did post it, so I will look at that, too.

    • RE: MMM-Chores - Manage and keep track of your household Chores

      @PierreGode – Thanks for the update on the data being available to AI. Since I don’t want my data available, I will just delete the module folder and remove it from the config file.

      Can you confirm that data is NOT stored anywhere outside the module folder? Thanks in advance.

      @PierreGode – Can you clarify your comment above comment above [quoted below]? If I read this correctly, the module is exposing the data it has to be scraped by AI engines.

      " … everything is still stored in data.json file and AI can use that as information "

      @redbeardedninja – Agreed! If the developer can make it work as you described it will be much more useable. Probably more intuitive to use, too.
