Shelly 1 Plus - Delay on turning on lights with dumb switch

Hi everybody,

I’ve a got a lot of shelly devices, that were working flawless until recently.

The only perceived change was that I activated the Bluetooth gateway on the shelly plus ones, for shelly BLU window/door sensors.

  • I activated the Bluetooth gateway on the shelly app and;
  • I activated the passive Bluetooth mode on the shelly plus devices on home assistant (using BTHome)

After this, I noticed that some lights (just the ones that use the shelly 1 plus relay, the others still work immediately) started getting slow on turning ON/OFF, even when using the numb physical switch. It’s a delay of only a second, but its strange because the lights used to turn on immediately.

Is there something that im doing wrong or should do to get them to work immediately again?

I guess it is because of the additional load on the mcu.
