- Fri Dec 24, 2021 4:08 am #93155 Is there any way I can access Linux shares from my ESP8266?

I'd like to light some LEDs based in the status of a file or two.

Thanks, Mark.

Or you could use an HTTP server that only lists the files you want to know the state of.

Shouldn't be too difficult.

Assumption is the mother of all f*ckups. At least: that's what I'm assuming.

- Thu Jan 06, 2022 3:43 pm #93279 Doing it over HTTP would be pretty easy. Make a PHP script that keeps an eye on the files you're interested in. Then have the ESP8266 pull up that page and fetch a value from it, then react accordingly.

For example, I have a remote sensor that works on variable deep sleep intervals. When the board uploads the current readings, the server stores them and returns it a value for when it wants the board to check in next. Example below.

Hope it helps!

Code: Select all    HTTPClient http;
    http.begin("http://192.168.210.5/collector.php?readings={\"air\":\"" + readingsAir + "\",\"light\":\"" + readingsLight + "\"}");
    int httpCode = http.GET();
    String payload = http.getString();
    http.end();

    naptime = naptime*1000000;
    Serial.println("Napping for " + String(naptime) + "us");
    ESP.deepSleep(naptime, WAKE_NO_RFCAL);
