In 2021 I made a MQTT notification Flag using a Servo and python code and webhooks to get notifications.
Webhook was used for Mattermost.

Mattermost Mqtt Flag Integration

Now i’ve changed the notification flag for Email using Thunderbird.
Just connect the wemos to a USB on your computer, no mqtt/wifi needed. (On the road solution)

Steps:

Install FiltaQuilla Add-on in thunderbird
select run program in config.

Next create a filter

Create two bash files (i’ve got mine in ~/bin/ )
Change ttyUSB0 if needed

::::::::::::::
flagoff.sh
::::::::::::::
#!/bin/bash
stty -F /dev/ttyUSB0 ispeed 9600 ospeed 9600 -ignpar cs8 -cstopb -echo
echo 0 > /dev/ttyUSB0

::::::::::::::
flagon.sh
::::::::::::::
#!/bin/bash
stty -F /dev/ttyUSB0 ispeed 9600 ospeed 9600 -ignpar cs8 -cstopb -echo
echo 1 > /dev/ttyUSB0

Install YAD and a autostart icon to make the systemtray to pull the flag down.

henri@zspot:~$ cat .config/autostart/servoflag.desktop

#include <Servo.h> 

Servo flag; 
char val;
 
void setup() {
  Serial.begin(9600);
  flag.attach(D5);
  }

void loop () {
  val = Serial.read(); 
  if (val == '0') {
     flag.write(180); 
  } 
  if (val == '1') {
     flag.write(0); 
  }
}
