 ===== Hardware =====
   * some glorious esp8266 in a Sonoff S20 power plug (NodeMCU v0.9 for development)
-  * another esp8266 to check when the S20 goes down (Fuz closing)
 To flash a Sonoff S20, solder the pins on the left of the push button, connect your USB-to-Serial convertor (RobotDyn CH340G in this case) to the headers like in the image below (from top to bottom, GND, TX, RX, 3.3v VCC), push Sonoff button while plugging in your USB-to-Serial convertor in your PC and then release the push button after a few seconds (check out [[https://medium.com/@jeffreyroshan/flashing-a-custom-firmware-to-sonoff-wifi-switch-with-arduino-ide-402e5a2f77b|this link]] and [[http://blinkingled.cc/update-firmware-of-smart-switch-sonoff-s20/|that one]]). Don't forget about the SPIFFS setting in Arduino IDE as we are using it to store custom settings via WifiManager (see step 6 below).

-  - **TODO** needs a publicly accessible server to serve an image/API (probably the same server as previous step), include the image/JS on fuz.re and yadda!

   - **TODO**
-Today the elementary functionalities described in step 2 are implemented [[https://gist.github.com/Lomanic/dba3cd9f93161cc1acc32c83197298eb|sonoff_s20_wifimanager_longpress_matrix_events.ino]].
+Today the button can notify on Matrix when it's pressed after initialization or after being notified on Matrix, and a server registers pings from the button to notify on Matrix that the Fuz is closed.
 Next steps:
+  - investigate random crashes after some time, integrate the awesome [[https://github.com/krzychb/EspSaveCrash|EspSaveCrash]] library, maybe do as this dude [[https://www.esp8266.com/viewtopic.php?f=6&t=18716&start=4#79055|here]], but sending crash to HTTP server
   - handle multiple matrix channels configured (to listen to and to reply to)
-  - notify when the Fuz is closing
   - resolve HTTPS locally instead of relying on a HTTP/HTTPS proxy
