Smart Outlets Restarting to ON State, Ignoring Last Relay State

Question

Hi, I have a problem concerning the Software:

Sometimes my outlets restart during the night. But when they turn back on, they don't assume the last state of the relais. They ALWAYS turn on.
During the night I'm always woken by this.

I already tried setting the start-up state on the relais to no avail.

The problem is reproducible by restarting the plug manually.

Maybe a startup command can fix it, but I could not find one.

Hello, what kind of platform and device?

For a classic Relay device, on the most of the platforms, setting a -1 in "Configure startup" for relay channel should be enough. However, if your device gets restarted by a watchdog for some reasons, you may indeed hear a brief click during restart. That being said, if startup is correctly set to -1, the relay should come back to the state that it was before the reboot.

I don't think that relays should turn on by default, unless you've set it excplicitly in the autoexec.bat or short startup command or startup menu.

Still, for a start, I would also suggest testing it without MQTT. We had similiar reports and it turned out that it was Home Assistant at fault.

I am creating multiplatform open source firmware (Tasmota replacement), right now supporting BK7231T, BK7231N, XR809, BL602, W800, W600, LN882H and soon supporting RTL and W701:

Yes that, solved the thing. Now it restarts to the last state.
I'm using btw the plug I flashed in my other post.

But that only partially fixes my problem, because I'm using homeassistant.
I am also a bit confused because all of my plugs are basically flashed with the same hardware and software, so why do I have these bugs only on some devices?

Maybe you have different flags? There are few flags that may alter HA behaviour. For example, "retain" flag setting. Or broadcasting value at MQTT connect. Etc. See here:

Check which flags do you have set.

Lots of details about the hardware and software in them and the software that controls the whole thing :]

I removed all flags it still shows this behavior.
I also checked with my other plugs, which work and copied their flags. But all to no avail.
I also took the obk config of one of the working plugs and sent it to the not working plugs but also no effect.

The workaround I found was to set up an automation in homeassistant, that checks when THIS plug goes unavailable and then turns on, it instantly turns it off.

Are there any new revelations. In this topic?

Electrical check, drying out capacitors cause reboots and swirling sockets/switches. I have this in my sonoffs, on average once a year one falls and I have to solder new nichicons there
