Hi everyone!
I have a quooker with a 2kg CO2 bottle attached to it. It often happens, that I notice too late that the CO2 bottle comes to an end and therefore I wondered if there are any ideas/hardware (that does not cost a fortunre) to make this smart and to visualize the remaining filling in %? I have a pressure reducer attached to it https://gase-kaufen.de/quooker-cube-umbau/571-druckregler-fuer-die-umruestung-quooker-cube-auf-co2-mehrwegflasche-4260509846493.html. The needle is around 50 when it is full. The space where this is installed is very tight.
I thought the best way to get accurate readings would be via the weight but I did not come across a good solution to measure this with HA compatiblity.
Maybe anyone has some ideas how to make this lett dumb
