Hello,
I have problem with powermon. It does not calculate correctly watt consumption.
As you can see on the picture the consumption in watts is 546W, but simple v*a calculation gives 617.74W.
So which value (if any) is correct W or A?
Also I've made a simple calculation in emoncms. Graph is also attached.

P.S.
Please excuse my bad english.

We don't calculate any parameters in esp8266 firmware. All values are coming directly from power monitor.
It looks like the power monitor issue

I've found a bug in JSON output:

...../readjson
gives me the following output
{"system":{"hostname":"Powermon","uptime":12,"rssi":-67,"freemem":33736},"sensors":{"pmv":234.2,"pmc":2.39;"pmw":459,"pmwh":75752,"ping":1},"gpio":{16:0}}

Please note that after "pmc" value there is a semicolon instead of comma("pmc":2.39;) and that causes parsing problems.

Ok. Fixed.

Found another bug:
In lines designer i have:
_DHTT1_°C _DHTH1_% _BMPP_mm
with test output:
24.0°C 42.1%.42mm

but when i remove % like this:
_DHTT1_°C _DHTH1_ _BMPP_mm
I get correct test output:
24.0°C 41.5 713.41mm

Can someone explain how can i use wunderground.com send ?
