- Buttons events source as button property instead of a global one - Rename events source -> provider for all settings, consistent with the other things like relay and light providers - AnalogPin to read between a certain analogRead() range Trying to follow defaults here - analog 'press' is digital LOW, default value is HIGH, so no additional cfg entries are needed besides pin, level and changing evt source - (debug) Refactor gpio command, add adc to show analogRead(pin) - (debug) Add button command Implemented based on: https://gitter.im/tinkerman-cat/espurna?at=5f5d44c8df4af236f902e25d https://gitter.im/tinkerman-cat/espurna?at=5f60e7f1f969413294e95370
