not an issue, mqtt autodiscovery idea for ha
Auto discovery is complicated, it is not working for me, I don't understand what it tries to do, so I played with code.
save-configuration.h
new function
void mqttSetup(String identyfikator, String chipId, String uom = "x" )
{
Serial.println("*****************************************" );
const String topicStr_c = "homeassistant/sensor/" + device_name + "-" + chipId + "/" + identyfikator +"/config";
const char* topic_c = topicStr_c.c_str();
Serial.println(topic_c);
StaticJsonDocument<1536> doc_c;
JsonObject root = doc_c.to<JsonObject>();
root["name"] = device_name +" "+ identyfikator;
root["state_topic"] = "homeassistant/sensor/" + device_name + "-" + chipId + "/status";
root["value_template"] = "{{ value_json['" + identyfikator +"'] }}";
if ( uom != "x" ) {
root["unit_of_measurement"] = uom;
}
//copy of existing sending code
// // Send to mqtt
char buffer_c[1536];
serializeJson(doc_c, buffer_c);
Serial.print("Sending message to topic: ");
if (logging) {
writeFile(SPIFFS, "/error.log", "Sending message to topic: \n");
}
Serial.println(buffer_c);
// Connect to mqtt broker
Serial.print("Attempting to connect to the MQTT broker: ");
if (logging) {
writeFile(SPIFFS, "/error.log", "Attempting to connect to the MQTT broker! \n");
}
// Serial.println(broker);
mqttClient.setServer(broker, port);
if (!mqttClient.connect(broker, mqttuser, mqttpass)) {
if (logging) {
writeFile(SPIFFS, "/error.log", "MQTT connection failed! \n");
}
Serial.print("MQTT connection failed! Error code = ");
Serial.println(mqttClient.state());
// goToDeepSleepFiveMinutes();
}
if (logging) {
writeFile(SPIFFS, "/error.log", "You're connected to the MQTT broker! \n");
}
Serial.println("You're connected to the MQTT broker!");
Serial.println();
bool retained = true;
if (mqttClient.publish(topic_c, buffer_c, retained)) {
Serial.println("Message published successfully");
} else {
Serial.println("Error in Message, not published");
goToDeepSleepFiveMinutes();
}
Serial.println("*****************************************" );
Serial.println();
}
called before making json for mqtt with measure values:
Serial.println("chipId " + chipId); //existing line
mqttSetup("daysOnBattery", chipId);
mqttSetup("battvoltage", chipId, "V");
mqttSetup("bat", chipId, "%");
mqttSetup("lux", chipId, "lx");
mqttSetup("humid", chipId, "%");
mqttSetup("soil", chipId, "%");
mqttSetup("salt", chipId);
mqttSetup("temp", chipId, "°C");
const String topicStr = "homeassistant/sensor/" + device_name + "-" + chipId + "/status"; //existing line
And with this changes measurements show itself in home assistant for me:
still don't know how to make the measurements to be possible to disable, I mean make them with unique entity_id
And question, it seems like there somewhere is log stored and other files, how to access them? I thought there is web server, or it should be visible as a portable drive but I can't find. Can anybody explain how to access log?
one more thing, because it can matter I changed original JSON to this, with one level structure:
StaticJsonDocument<1536> doc;
// Set the values in the document
// Device changes according to device placement
JsonObject plant = doc.to<JsonObject>();
// JsonObject plant = root.createNestedObject("sensor"); //CHANGE!!!!!
plant[device_name] = chipId;
plant["sensorname"] = plant_name;
plant["date"] = config.date;
plant["time"] = config.time;
plant["batchargeDate"] = config.batchargeDate;
plant["daysOnBattery"] = config.daysOnBattery;
// plant["battvolt"] = config.batvolt; //nie
plant["bat"] = config.bat;
plant["battvoltage"] = config.batvoltage;
plant["sleep5Count"] = config.sleep5no;
plant["bootCount"] = config.bootno;
// plant["batcharge"] = config.batcharge; //nie
plant["lux"] = config.lux; //nie
plant["temp"] = config.temp;
plant["humid"] = config.humid;
// plant["pressure"] = config.pressure;
plant["soil"] = config.soil;
// plant["soilTemp"] = config.soilTemp; //nie
plant["salt"] = config.salt;
// plant["saltadvice"] = config.saltadvice;//nie
// plant["plantValveNo"] = plantValveNo; //nie
// plant["wifissid"] = WiFi.SSID(); //nie
plant["rel"] = config.rel;
with two level structure one have to change json templates to read measurements.
entity_id solved. Because there are lot of changes in the file, full content:
void mqttSetup(String identyfikator, String chipId, String uom = "x", String dc = "x" )
{
Serial.println("*****************************************" );
const String topicStr_c = "homeassistant/sensor/" + device_name + "-" + chipId + "/" + identyfikator +"/config";
const char* topic_c = topicStr_c.c_str();
Serial.println(topic_c);
StaticJsonDocument<1536> doc_c;
JsonObject root = doc_c.to<JsonObject>();
root["name"] = device_name +" "+ identyfikator;
if ( dc != "x" ) {
root["device_class"] = dc;
}
root["unique_id"] = chipId +"-"+ identyfikator;
root["state_topic"] = "homeassistant/sensor/" + device_name + "-" + chipId + "/status";
root["value_template"] = "{{ value_json['" + identyfikator +"'] }}";
if ( uom != "x" ) {
root["unit_of_measurement"] = uom;
}

and nice result in entities
@Maaciej, as I am setting up some new sensors for HA I will give this a try. Is it the intention to replace the content of the file "save-configuration.h" with your code as mentioned above?
Is it the intention to replace the content of the file "save-configuration.h" with your code as mentioned above?
yes this whole save-configuration file content customized (unnecessary fields of json commented out and changed json structure) for my needs, with added mqtt autodiscovery for ha. I guess you change your file to above and should see that ha will detect configured metrics.
And question, it seems like there somewhere is log stored and other files, how to access them? I thought there is web server, or it should be visible as a portable drive but I can't find. Can anybody explain how to access log?
files in question are:
Listing directory: /
FILE: favicon.ico SIZE: 13532
FILE: index.html SIZE: 482
FILE: app.js.gz SIZE: 198509
FILE: batinfo.conf SIZE: 21
FILE: error.log SIZE: 1342
FILE: soil.conf SIZE: 9
FILE: name.conf SIZE: 9
files with extension .conf are from the program, and unknown are the first three.
I suspect now they are from the original firmware.
They cannot be removed by "remove",
but I erased all files with SPIFFS.format()
and now have only new files:
FILE: name.conf SIZE: 9
FILE: batinfo.conf SIZE: 21
FILE: soil.conf SIZE: 9
Hi, i found a few issues with the above. Mainly having a device and sensor names. So updated some, added some,.
