Please input the buttons in order of completion after the 1st crack (1st crack) and 2nd crack (as appropriate) from the start of roasting.
The roasting start time and time (1St/2nd/Complete) can be saved to the "clipboard" when the reset button is pressed. Please link data to other apps as a roasting record.
If you have a SwitchBot (temperature and hygrometer), you can enter the MAC address to display the temperature of the Bot in a graph. (Default measures battery temperature in terminal)
Although it is a third party, I think that it would be nice if we could create a sensor that can measure the temperature inside the furnace that is compatible with SwitchBot's Advertisement packet format.
