* ESPHome MagTag Example
The Adafruit MagTag has a bunch of nice features which makes it a
desirable board for ESPHome.
- A 2.9 inch e-ink display
- Light sensor
- Speaker with built in amplifier (for simple tones)
- 4 NeoPixel colour changing LEDs at the top
- 4 buttons at the bottom
- Accelerometer (not used in this example)
This example includes some functionality for the first 5 items. While
the display is not a Waveshare 2.9 inch display (it uses a "Good
Displays" e-ink display), it does seem to be mostly compatible. I've
not got greyscale working yet, so it's either on or off. It currently
drawers some graphs and shows the time, plus some other little bits
which are specific to my Home Assistant setup. I'd like to add a text
notifier service at some point in the future. It would be nice to be
able to use the built in speaker with RTTTL but I was unable to get
this working. Instead, I provide the Adafruit example coin sound, plus
a doorbell sound which I generated from an online sound file. These
are exposed as Home Assistant services, so you can use it (for
example) as a doorbell speaker.
The light sensor state is reported every 30 seconds as a voltage
level - I've not attempted to try and convert this to a more useful
unit. The four buttons at the bottom show up in Home Assistant as
actual buttons, so can be attached to automations.
During development there is/was a bug in the Waveshare 2.9in drawing
function which simply draws all back instead of the actual image
data. I'm not sure if there was a reason for this but I submitted a
pull request to output the buffer byte instead. It's not been merged
(yet).
