Sonoff POW R2 readings - Calculating costs? :)

[pppaulie_s (Paul)]

G’day @Orion,

Please see below for my Washing Machine and Dryer YAML.

• This creates sensors to measure the volts, amps, watts etc.
• It also uses “templates” to calculate costs for “yesterday” and “todays” usage (@ 0.35cents AUD per KWh)
• It also notifies me (automation) through my SONOS via TTS (Bedroom and Living Room) when the cycle is complete
