* Add Shelly 2.5

* Add ADE7953 sensor support

* Fix compilation

* Use only one instance

* WIP: Not working, I got StoreProhibited exception

* Fix exception

* Fix merge issues

* Apply request review changes

* declare struct before using it

* uninterruptible delay

* try optimized reg_size

* fix types

* Remove gpio 0 input in analog sensor

* Add energy to ADE7953, it is not finished yet

* Add new method to save energy with index

* Finish energy for ADE7953

* Core 2.6.0+ fixes

* fix env -> config, run travis04 job

* don't duplicate free heap in frag data, use single stats struct

* fix dtostrf warnings, bump buffer sizes

* ...and even less words for fragmentation stat

* enable multiple Digital, Events & PulseMeter

* delete SPI dependency

* back to only one PulseMeter

* deprecared pins

- cache ms<->clockcycles conversions
- move callback invocation outside of ISR handler
- remember last event value

- dynamic number and address setting
- do not return i2c-specific error for wrong values

* Add reactive power calculation and bring output to in line with HLW8012 sensor based units

* Update CSE7766Sensor.h

* Fix energy ratio input for pulse meter sensor

* checkout origin/dev -- webui files

* Testing branch

* Added ability (by define) to scale analog sensor, also with number of decimals (it was formerly zero)
Useful when running on batteries to check the battery voltage just 
adding the appropriate resistor

* Reverting DHTSensor.h file

* Trying again to revert DHTSensor.h

* Using macro DEBUG_MSG

* fix method types
