Recently swapped over to your integration @wlcrs - nice work!
Decided to swing you some sponsor love, as should everybody else on this thread gaining from your efforts 
Everything works perfectly other than a strange issue I’m seeing in my Influx/Grafana logging…
My brain has always preferred to see instantaneous active power usage vs kWh, so a basic formula gives me the figure I like to see on my dashboards:
huawei_house_usage:
friendly_name: "Huawei House Active Power Usage"
value_template: "{{ (states('sensor.inverter_active_power') | float) - (states('sensor.power_meter_active_power') | float) }}"
What I’ve found since swapping to your integration are small transient figures logged as negative.
This is obviously impossible!
I believe this is due to the fact there are now two ‘devices’, and the small fraction of a time difference between both devices ‘reporting’ is causing bogus information to be logged in the template resultant figure.
(hanging out for these sporadic clouds to bugger off haha!)
Any ideas how I can combat this? I thought of rejecting negative figures in my fluxdb query but I’ve seen errors above zero as a result of the formula too.
Cheers!
