'end of noon'? If it's dark out, the micros do consume a small amount of current.
In my system with 23 total inverters and the older oval Envoy, m190 / m210 and replacement m190IG/IQ7, the system does consume 10 to 11 watts total at night, measured by my utility meter. My Envoy is powered directly from the same circuit so that would be using 1-3watts. I see zero or some small value reported by the Envoy at night, 10 to 40 watts, and I think this may be the last values reported from the micros before they turn off.
Thanks. It now shows 0 again (which I would expect). I apparently looked exactly at the 'right' time to notice the effect.
The micro inverters use power overnight? I have 15 iQ7+ installed. Maybe the iQ7(+) make a difference in that aspect?
Still strange that the value reported in Home Assistant was different from the value reported by the API.
@lnlp Sorry for the late reply. If I remember correctly you have an Envoy-S? The current watts now value would be coming from /production.json
. This could account for the difference.
@lnlp I suspect this is still and issue?
I was looking at a different issue today and saw that the Production value from a Production CT was negative in the /production.json
output: "wNow":-0.719
This negative value is then seen as a -1 W
through the Envoy webpage sometimes, mostly it shows 0 W
.
Wondering if I should just change the value to zero if a small negative value is retrieved via the API for Production data?

@gtdiehl
Today I noticed reporting of negative
whattsNow
value in the Home Assistant Enphase Envoy plugin (labeled 'Actueel' on screen):However
envoy/api/v1/production
showed an activewhatssNow
value of 0:A short moment later (I refreshed both screens) the values were as follows:
I'm not sure why the Envoy does report negative
whattsNow
values and this is not something caused byenvoy_reader
.It is strange however that the negative whattsNow values reported in Home Assistant are different from the ones reported by the Envoy api
envoy/api/v1/production
.This is either caused by a problem in envoy_reader or the Home Assistant Enphase Envoy plugin.
How is it possible that the Envoy api reports a negative
whattsNow
value?Values were observed at end of noon while it was almost dark. Envoy Metering Multiphase without CT metering installed.
