dalej nie rozłącza AP. Możesz udostępnić mi twoje biblioteki ?

Of course.
I attach the latest version of 8x8_595_ntc and the libraries.

Hi elmaya
I make work this software and got following behaviour: when power on D1 mini - relay is getting high signal. Is this as designed? Is there option to make a bin file with default low signal send to relay after powering on?
PS I did not install buttons as i dont need them but I suppose this should not have any influence.

[elmaya]

you have to use high-level trigger relays.
What kind of relay do you have?

[Remi]

I use these ones:



I performed more tests and it looks old position of relay is remembered but... anyway relay is supplied for approx 2 seconds after powering up and then it goes to previous state.
Also there is inversion when comparing app and phisical relay - is there option that i connected incorrectly hc595?

[elmaya]

that type of relay does not work well when controlled with 3.3v and is active at low level

you will have to use something else.

The easiest and fastest way will be to use other relays. Wemos relay shield works well base on my performed tests so far. Thx for help

what would I have to change for the bistable input to work in the code?

you should not use this as it is obsolete.
consider using MCP23017 with the current Supla library.
with "GUI Generic" it will be easy.
