Soda Counter

I wanted to keep track of the amount of bottles with carbonated water I can pull from the soda stream device after replacing the CO2 cylinder.

As the individual amount of CO2 per bottle depends on how often you press the push button of the soda stream device, I glued a magnet to push button mechanic which closes the reed switch when the button is pressed down.

The actual counting is done by a ESP running ESPEasy.

Magnet, reed switch + ESP fit well into the top of the soda device. A USB cable is connected to the ESP and a USB power supply.

I added a rule, so the blue onboard LED of the ESP lights when the reed switch is closed / the button is pushed.

To get the current amount of pulls just visit the ESPs web GUI or forward the stats to your central home automation solution.
