Hi there, It is not problem that board is erased but the thing that is unreliable. I used the board to control my heater in flat. In case that something goes wrong with board I can set flat on fire. Now I am using arduino and rtc just to be sure. But nevertheless I like this board and would like to ...

The board is so tiny, it wouldn't surprise me if it had no such function. A good idea might be to hook it up to a cell phone charger battery. I bought one for my Rpi and it keeps the thing powered for 3 days on one charge. It would be best if the cell phone charger battery has both an in port and a...

I assuem that I can turn on pullup resistor and use the pin in inverted mode?

Yes.

Thank you very much

You have to show the module, since not all boards have that button. But if it is the button to enable boot mode: that one is connected to GPIO0 and it can be used with the machine.Pin() class. Doing that, you might have to deal with debouncing. But a search for that word in the forum will retrieve ...
