A tiny RESTfull API for opening an old intercom that has to emulate reciever pick-up and after setupable delay closing the physical gate circuit.

• make a fritzing schematic

• find out the current going through the phycisal gate circuit when opening the gate

• post photos of the intercom circuit

• json config load (arduinoJson6)

  • try the official example way with a struct Config ?
  • find Guy with the Swedish Accent's approach with ArduinoJson5 and see how to pin the lib in platformio.ini

• if that doesn't work - fallback to either arduinoJson5 or line parsing a text file

• create a user at my http server for OTA

• OTA

• HTTPS letsenrypt → for PUT on /config
• multi WiFi credentials
• GitLab CI/CD integration (Docker)
• Authentication for sensitive endpoints (or all? - configurable)

• GET: /open or /o > get method for easier cli integration like so: curl 192.168.1.101/open
• GET: /health or /h
• PUT: /delay_ms?t=500
• PUT: /pulse_length_ms?t=500
• GET: /restart
• PUT: /OTA/address?a="http://lepi.pl/OTA/RPLUS-intercom"
• GET: /OTA/reload > check for updates at address
• GET: /config → json with config but only https and with AUTHENTICATION

• resistors: 2x 1kohm [min.500ohm (over 1kohm doesn't close the relay) (12mA per pin on Wemos)]
• transistors: 2x CTBC 547B JS (I hope they're not running JavaScript xD)
• 2x relay RZ2 G4,5 ITT West Germany (>29 yrs old)
• micro-usb power supply
