Weird behaviour with more than two things

[lennart-k]

So I'd like to use expose five things with my ESP32:
The status LED and four relays.
This is my horrible code:

#include <Arduino.h>
#include "Thing.h"
#include "WebThingAdapter.h"

const char *ssid = "SeInternetzOfSings";
const char *password = "DieWolke";

WebThingAdapter *adapter;

const int statusLedPin = 2;
const int relay1Pin = 15;
const int relay2Pin = 4;
const int relay3Pin = 22;
const int relay4Pin = 23;

const char *ledTypes[] = {"OnOffSwitch", "Light", nullptr};
const char *relayTypes[] = {"OnOffSwitch", "SmartPlug", nullptr};

ThingDevice statusLed("led", "Built-in LED", ledTypes);
ThingProperty statusLedOn("on", "", BOOLEAN, "OnOffProperty");

ThingDevice relay1("relay1", "Relay 1", relayTypes);
ThingProperty relay1On("on", "", BOOLEAN, "OnOffProperty");
ThingDevice relay2("relay2", "Relay 2", relayTypes);
ThingProperty relay2On("on", "", BOOLEAN, "OnOffProperty");
ThingDevice relay3("relay3", "Relay 3", relayTypes);
ThingProperty relay3On("on", "", BOOLEAN, "OnOffProperty");
ThingDevice relay4("relay4", "Relay 4", relayTypes);
ThingProperty relay4On("on", "", BOOLEAN, "OnOffProperty");


void setup(void) {
  pinMode(statusLedPin, OUTPUT);
  pinMode(relay1Pin, OUTPUT);
  pinMode(relay2Pin, OUTPUT);
  pinMode(relay3Pin, OUTPUT);
  pinMode(relay4Pin, OUTPUT);
  
  Serial.begin(115200);
  Serial.print("\nConnecting to \"");
  Serial.print(ssid);
  Serial.println("\"");

  WiFi.mode(WIFI_STA);
  WiFi.begin(ssid, password);
  Serial.println("");

  // Wait for connection
  bool blink = true;
  while (WiFi.status() != WL_CONNECTED) {
    delay(500);
    Serial.print(".");
    digitalWrite(statusLedPin, blink);
    blink = !blink;
  }

  Serial.println("");
  Serial.print("Connected to ");
  Serial.println(ssid);
  Serial.print("IP address: ");
  Serial.println(WiFi.localIP());
  adapter = new WebThingAdapter("w25", WiFi.localIP());

  statusLed.addProperty(&statusLedOn);
  adapter->addDevice(&statusLed);

  relay1.addProperty(&relay1On);
  adapter->addDevice(&relay1);
  
  relay2.addProperty(&relay2On);
  adapter->addDevice(&relay2);
  
  relay3.addProperty(&relay3On);
  adapter->addDevice(&relay3);

  relay4.addProperty(&relay4On);
  adapter->addDevice(&relay4);
  
  adapter->begin();
  Serial.println("HTTP server started");
  Serial.print("http://");
  Serial.println(WiFi.localIP());

}

void loop(void) {
  if (WiFi.status() != WL_CONNECTED) {
    Serial.print("Connection lost, reconnecting");
    WiFi.reconnect();
    bool blink = true;
    while (WiFi.status() != WL_CONNECTED) {
      delay(500);
      Serial.print(".");
      Serial.println("");
      digitalWrite(statusLedPin, blink ? LOW : HIGH);
      blink = !blink;
    }
    Serial.println("Reconnected");
  }

  adapter->update();

  digitalWrite(statusLedPin, statusLedOn.getValue().boolean);
  digitalWrite(relay1Pin, relay1On.getValue().boolean);
  digitalWrite(relay2Pin, relay2On.getValue().boolean);
  digitalWrite(relay3Pin, relay3On.getValue().boolean);
  digitalWrite(relay4Pin, relay4On.getValue().boolean);
}

The weird thing is that I only get the led and relay1.
Relay 2-4 are nowhere displayed and cannot be accessed using the REST API.

Now when I comment out

statusLed.addProperty(&statusLedOn);
adapter->addDevice(&statusLed);

then only relay 1 and 2 get listed:

[
  {
    "id": "relay1",
    "title": "Relay 1",
    "@context": "https://iot.mozilla.org/schemas",
    "base": "http://192.168.3.103/",
    "securityDefinitions": {
      "nosec_sc": {
        "scheme": "nosec"
      }
    },
    "security": "nosec_sc",
    "@type": [],
    "links": [
      {
        "rel": "properties",
        "href": "/things/relay1/properties"
      },
      {
        "rel": "actions",
        "href": "/things/relay1/actions"
      },
      {
        "rel": "events",
        "href": "/things/relay1/events"
      },
      {
        "rel": "alternate",
        "href": "ws://192.168.3.103/things/relay1"
      }
    ],
    "properties": {
      "on": {
        "type": "boolean",
        "@type": "OnOffProperty",
        "links": [
          {
            "href": "/things/relay1/properties/on"
          }
        ]
      }
    },
    "href": "/things/relay1"
  },
  {
    "id": "relay2",
    "title": "Relay 2",
    "@context": "https://iot.mozilla.org/schemas",
    "base": "http://192.168.3.103/",
    "securityDefinitions": {
      "nosec_sc": {
        "scheme": "nosec"
      }
    },
    "security": "nosec_sc",
    "@type": [],
    "links": [
      {
        "rel": "properties",
        "href": "/things/relay2/properties"
      },
      {
        "rel": "actions"
      }
    ]
  }
]

But now I can access all relays with /things/relay[1-4].

I'm using [email protected] with PlatformIO.

Oh, I don't why but now the only error is that not every relay gets listed and I bet its a duplicate of #10

Yeah, just had to set LARGE_JSON_BUFFERS for anybody wondering in the future.
