State changes after 10 seconds with switch use

  • Hi,

    I'm in the UK and have 2 Shelly Dimmer 2's installed with dimmable spots. Everything is working fine for the most part except that sometimes after the rocker switch is used to toggle the lights they then do the opposite after 10 seconds. This is really annoying if you leave the room and switch them off only to come back later & find they are back on again.

    I have the switch mode set to Edge on both dimmers as this is the only mode that appears to offer the expected behaviour except for this issue.

    I was testing again this morning using a combination of the app and physical switch and one of them did it again, but not both.


    Firmware is 20211109-131033/v1.11.7-g682a0db on both devices.

    I have attached debug logs from the one of them that just did it again this morning.

  • I’ve been having this issue too on a few of my dimmers. All using a rocker switch and edge mode. Seems to be random as it doesn’t happen every time. Happened again just now on firmware version 20221027-104444/v1.12.1-ga9117d3. Just upgraded to 20230913-114008/v1.14.0-gb84623, so we’ll see how that goes.

  • So this is still happening occasionally. Have either of you found a solution?

    I’m not able to prove it, but I think it might be something to do with the Shellies disconnecting from the wifi. They are reconnected when it happens though. I’m using Unifi access points and have a dedicated 2.4Ghz network for them.
