Multiple sensors @ESP32

[ssditt]

All my recent projects work fine with UNO or ESP8266. Thanks Dawid! Today, I need 6 sensors @ESP32:

include

include

define BROKER_ADDR "192.168.1.10"

define MAC_ADDR_LENGTH 6

byte mac[] = "NAMFV1"; const char unitName = "NAMFV1"; const char unitVersion = "A1"; char WiFi_SSID [] = "ssid"; char WiFi_pasw [] = "pswd"; WiFiClient client; HADevice device(mac, MAC_ADDR_LENGTH); HAMqtt mqtt(client, device);

HASensor data("V"); HASensor dataL("A"); HASensor wattage("W"); HASensor voltageL("VL"); HASensor amperageL("AL"); HASensor wattageL("WL");

void setup() { Serial.begin(9600); Serial.println("Starting..."); WiFi.begin(WiFi_SSID, WiFi_pasw); while (WiFi.status() != WL_CONNECTED) { Serial.print("."); delay(500); } Serial.println(" Connected to the network");

device.setName(unitName); device.setSoftwareVersion(unitVersion);

mqtt.begin(BROKER_ADDR); }

void loop() { mqtt.loop(); }

---

But I get only 5 sensors to MQTT - the last one is missing. And all stat_t contexts are defined with "aha" prefix: { "uniq_id": "V", "dev": { "ids": "4e414d465631", "name": "NAMFV1", "sw": "A1" }, "stat_t": "aha/4e414d465631/V/stat_t" }

Finally I can get it worked merging sensor data into less sensors and it works with different context for stat_t, but it should be great to have standard functionality @ESP32

https://dawidchyrzynski.github.io/arduino-home-assistant/documents/library/device-types.html By default the number of devices is 6. Did you try setting it?

I have got all 6 sensors in MQTT with the line HAMqtt mqtt(client, device,8);

Any idea what's wrong with prefix "aha" in stat_t context? It is still there with all sensors...

[ssditt]

rikki78, thanks for the link! I have found the "aha" is a default prefix for data (stat_t) context. It is a new against older versions.

So the conclusion is that despite defualt limit 6 devices the program registers 5 devices only.

Hi @ssditt,

The aha prefix is a configurable data prefix. It's described here: https://dawidchyrzynski.github.io/arduino-home-assistant/documents/library/discovery.html

If it comes to limit, there is a known bug in the entities limiter that will be fixed soon. For now please use a limit higher by one (in your case it should be 7).
