Shelly Plus 1 with latest version not discovered

[sbender9]

The device is not discovered initially. If I restart the device after discovery is started, then it is found.

the mdns discovery stuff only gets the PTR record, no A record. On restarting the device, it gets all the expected records.

Not sure if this is an issue with the new firmware or an issue with the mdns discovery library.

I'm also getting this problem and device restart is working a treat, did you ever find a work around @sbender9

[sbender9]

If I recall correctly, I reverted to an older firmware on the Shelly.

@sbender9 do you have a source and a version number for a "known good" firmware?

[sbender9]

I can't get to the device right now, but can check for sure later today.

But I think it was that latest 1.x that worked, v2.x didn't. It's also possible that this has been fixed in newer 2.x, it's been a while since I tried.

I can confirm that this issue exists still in gen2 firmware 1.3.2

[sbender9]

We are two years since the last release.has anyone taken this over?

[sbender9]

@alexryd what are your plans?

It still does this, even with the newest firmware. My solution was a node red flow that reboots all my shelly's upon restart of SK. Not very elegant, but it works. Is there a different command to make the shelly's re-announce themselves besides "Shelly.Reboot"?

I solved the issue for me using avahi and a custom discoverer that can be used analogous to the mDNS discoverer (edit: according to their website avahi is shipped by default in most Linux distros, so it should work out of the box, as long as it is enabled):

class AvahiDiscoverer extends DeviceDiscoverer {
   protected proc: ChildProcess;

   start() {
      this.proc = spawn('avahi-browse', ['--parsable', '--resolve', '_shelly._tcp']);
      let output = '';
      this.proc.stdout.on('data', data => {
         output += data.toString();
         let index: number;
         while ((index = output.indexOf('\n')) >= 0) {
            const line = output.substring(0, index);
            const parts = line.split(';').map(part => part.trim());
            output = output.slice(index + 1);
            this.handleDiscoveredDevice({
               deviceId: parts[3],
               hostname: parts[3]
            });
         }
      });
   }

   stop() {
      this.proc?.kill();
   }
}
