Hi,
at first I wanted to say, I'm not a coder by any means 
(this is double of this post Shelly watchdog - restart), but maybe here is more suitable place for it.
So my goal is to have a script which checks if a Shelly is able to reach the Internet and if not, Shelly should be restarted. Sometimes a few Shellies lose their connection and the only way to reconnect is to restart a Shelly itself.
I have tried to modify existing script and my outcome looks like:
Code
// This script tries to execute HTTP GET requests within a set time, against a set of endpoints
// After certain number of failures the script resets the shelly
let CONFIG = {
endpoints: [
"https://global.gcping.com/ping",
"https://us-central1-5tkroniexa-uc.a.run.app/ping",
],
//number of failures that trigger the reset
numberOfFails: 5,
//time in seconds after which the http request is considered failed
httpTimeout: 10,
//time in seconds to retry a "ping"
pingTime: 60,
};
let endpointIdx = 0;
let failCounter = 0;
let pingTimer = null;
function pingEndpoints() {
Shelly.call(
"http.get",
{ url: CONFIG.endpoints[endpointIdx], timeout: CONFIG.httpTimeout },
function (response, error_code, error_message) {
//http timeout, magic number, not yet documented
if (error_code === -114) {
print("Failed to fetch ", CONFIG.endpoints[endpointIdx]);
failCounter++;
print("Rotating through endpoints");
endpointIdx++;
endpointIdx = endpointIdx % CONFIG.endpoints.length;
} else {
failCounter = 0;
}
if (failCounter >= CONFIG.numberOfFails) {
print("Too many fails, resetting...");
failCounter = 0;
Timer.clear(pingTimer);
Shelly.call("Shelly.Reboot");
}
}
);
}
print("Start watchdog timer");
pingTimer = Timer.set(CONFIG.pingTime * 1000, true, pingEndpoints);I have checked and it looks like the script works. Maybe someone could check/advise if it is ok. Maybe some improvement could be made.
Thanks in advance.
The device is behind to much firewalls but it can ping google for example. the http get method doesn't work for me.
