Post by ropske » Sunday 18 December 2016 13:09

Hi,

Someone else also has this problem and knows how to fix this?

@ropske

For understanding your problem, please explain how your electricity-values are measured:
P1-meter at grid-interface, or 'own' kWh-meter?
Is it only Consumption, or is it Consumption & Return due to PV-Production?

What is the change in the numbers if you look a few days?
Set1 = RPI-B+RFXCom433+S0PCM+Linksprite-shield for BMP180/DS18B20/RS485+DDS238-1ZN
Set2 = RPI-3+RFLinkGTW+ESP8266s+PWS_WS7000
Common = 3*PVLogger+PWS_TFA_Nexus+KAKUs
=> Energy & Data Management based on Time and on PV&Consumption&Meteo

@ropske

OWL CM180 Single phase OK, but question related to application of the meter is unanswered:
at what cable are you measuring the Power/Energy?
In other words, is the meter fitted between a device and the 230V-network, or other configuration?
What type of device?
