Power cut cause relay to get activated upon boot

[grovkillen]

I have a simple relay that I really like since it is compatible with 3.3V logic levels (not only 5V). It works great but if I get a power outage / cut the ESP will not boot correctly since it will send a signal to the relay causing it to activate. This happens as soon as the ESP get power. I have tried to use the hardware tab to make the GPIO boot as low but it does not work. I have fixed it by having a switch that cuts the cable, and I then have to have this manually switched to off until the blue led comes to shine. Am I missing something obvious here?

The relay board that I use is found here.

Another thing to consider. If I put the GPIO 16 to have a boot state of HIGH (or was it low?) I will not be able to save settings to the flash memory. My only way of fixing this was to re-flash the unit to get it to be writable again. Should this be mentioned within the GUI?

Maybe just use the pcf8574, it keeps states during reboot, I tried.

i'm not sure if this is documented properly. if you can still reproduce it, could you file a bug report on github? that way i will take a look at it later and perhaps fix it or disable that GPIO from the hardware settings or something. (or perhaps a link to the wiki in the web gui)

I will try to reproduce.

I cannot reproduce, please consider this related to the write limit for flash memory.
