Buy an Amazon dash button - I know you don’t want to buy anything but the dash button is the cheapest(Germany 2€ plus 5€ voucher), easiest way to realize your button.
If you still want to build it by yourself use mqtt-plugin and Google for the sketch
Thank you all for your replies. I have already Dash Buttons in my Environment and it works Fine - Not perfect but fairly good enough for me.
But in this case I want a Button which looks like a buzzer so a dash Button is Not the solution …
first of all i´m sorry for my bad english and then i want to thank everyone on the development team - pimatic is really great!
I want to build a “buzzer” wifi button with an Arduino nano or the ESP8266 … however this button should control some of the pimatic devices. So my question is: Is this possible and how?
I´m not looking for an exact and polished how to but if this is not possible I don’t want to buy the hardware.
Thank you for your help!
