Node for paying for spot heating. It is a variation on the payment terminals used for coffee and beer.
See SpaceTegoed voor een overzicht/plan, Payment and Paring REST protocol for the protocol and [github for code].

What does it do
Swipe ones to get 15 minutes of heating. Swipe twice for 30 minutes; and so on. The display will show 15:00, 30:00 and so on. And then change every second to 14:59, 14:58 and so on.
Once you've swiped - the display changes from the price to a countdown.
During this time the heating is on. Once it reaches 00:00 - the heating switches off.
Trouble shooting
It is possible to 'telnet' into these units (on the normal telnet port #23) and see what normally would come out of the serial port. The units also sent their logging to syslog (to the spaceserver, 192.168.6.1).
Check the firewall, use a [MDNS] [resolver] (or simply the Arduino IDE) to discover their IP address. You can do this from the RaspPi next to the VinylCutter / Vinylsnijder.

NodeSpotHeating | 1.65 | ???? | 192.168.6.??? |
Version deployed as of September 2022: https://github.com/dirkx/makerspaceleiden-payment-node-7segments/releases/tag/v1.06
A typical session looks like:
$ telnet 10.13.0.241 23 4x7-F1-05-430fe4 Serial connected 3C:71:BF:43:0F:E4 Good scan Payment completed successfully. Wed Nov 3 19:02:11 Heap: 181 Kb
Any error message (post joining the Wifi network) will show up here. If the issue is prior to joining WiFi - you will have to connect a USB cable (Baudrate 115200, 8N1). The Raspi has the right drivers installed.
Furthermore - if you connect to space.makerspaceleiden.nl
via MQTT - then you can also see the output:

Compileren software
- Installeer een recente versie van [[1]].
- Installeer een stable versie van de SDK voor de ESP32 volgens https://docs.espressif.com/projects/arduino-esp32/en/latest/installing.html
- Selecteer in tools het platform ESP32 en dan het board dat je gebruikt (WRover, Devkit)
- Installeer via de 'Library' optie de bibliotheken MFRC522-spi-i2c-uart-async, TM1637TinyDisplay en Arduino_JSON
- Haal een git/zip versie op van https://github.com/MakerSpaceLeiden/makerspaceleiden-payment-node-7segments/
- Zet de #defines met de netwerk namen goed. Kies een unique terminal naam.
Overleg met noc@ voor een 'bearer token' voor toegang als je de productie versie maakt.- Idem voor het OTA wachtwoord.
- Compiler & flash via serial (daarna kan het via OTA).
- Nota bene: with the cheaper boards; it may be needed to press 'BOOT' during the start of the programming.
