4 years ago Hi,
I just installed "node-red-contrib-ewelink" and it is great, really appreciated!
I have a farm with an offgrid solar system distributing power to four tenants, all with POWR2s into their respective houses.
It would be really great to be able to monitor the tenants continuous consumption and have a Node Red dashboard with gauges showing their "data" on their wall mounted tablets.
They already use Ewelink app for installed Sonoff products. To change to Tasmota would be a real challenge for them since they aren't so technically skilled ;-).
Thanks in advance!

Hello, using the eWeLink app. it is possible to view the instantaneous values of the Voltage, Current & Power, from the POWR2. The accumulated Energy Consumption kWh (power usage over time) is useful, the instantaneous values would be additionally useful, and in someways more useful, on NodeRed, where decisions could be made on, say overcurrent monitoring, Voltage monitoring (voltage drops causing failure) or power monitoring for load shedding. I feel sure many would find this useful & and it is available in Tasmota : Message | Unit | Description
TotalStartTime | Date | DateTime of calculation for Total Total | kWh | Total Energy usage including Today Yesterday | kWh | Total Energy usage between 00:00 and 24:00 yesterday Today | kWh | Total Energy usage today from 00:00 until now Period | Wh | Energy usage between previous message and now Power | W | Current effective power load ApparentPower | W | Power load on the cable = sqrt(Power^2 + ReactivePower^2) ReactivePower | W | Reactive load Factor | | The ratio of the real power flowing to the load to the apparent power in the circuit Voltage | V | Current line voltage Current | A | Current line current
Is it possible for you to implement this feature?
So that out of the box Sonoff POWR2 can be used without re-flashing. That is the value of your NodeRed contribution no re-flashing!
Thank you for what you have done it is great so far.
😎👍
