OpenBeken rebooting when simultaneously switching off two relays at the same time. #923

Open NielsPiersma opened 11 months ago

NielsPiersma commented 11 months ago

Describe the bug When using the Show Header Toggle in HomeAssistant to power OFF two relays at the SAME time, the device will reboot. when toggling independently, all works fine.

Firmware: Version 1.17.244 Device: LEDVANCE SMART WIFI ORBIS KITE RD 410 TW WT Chip/model: BK7231T Device config P7 (PWM1) LED 1 P8 (PWM2) LED 0 FLAGS: 134218752

To Reproduce Steps to reproduce the behavior:

  1. Go to 'HomeAssistant'
  2. Toggle the Header above the device with two relays
  3. See ping disapear

Screenshots

powered on powered off and rebooting

Additional context Maybe this can be solved by adding some delay for switching the secondary relay. There is nothing logged in the log it silently reboots. Only found it because I needed to power the lights on again after turning them of by accident.

Hello, do you have PowerSave 1 (enabled low power mode)?

No, I've not enabled PowerSave 1, tried explicitly with "PowerSave 0", but to no avail.

It instantly reboots when toggling both switches simultaneously.

But I think it must have something to do with the power drawn, as when I configure a bogus (chip only on a breadboard) with two relays or two leds I can switch them off both simultaneously without any problem.

The workaround is not that difficult, adding a few ms of delay in the automation and not using the header toggle keeps the device from rebooting.

this sound like a power problem to me. while activating 2 relays the voltage drops to much an the device reboots.
