Habe das gleiche Problem. Mit 0.10.3Beta1 war der Wert gleich 5mal so hoch. Mit Beta2 noch etwa 30% darüber, das hat man wohl so zur Final gemacht. Hat mir schon die Spitzenwerte und einige Tage der Statistik Versaut.

@mircho.mirev

Seems accumulated energy is still wrong on 0.10.3 final, somewhere at 30% to much like reported by dana_se before. Please refer to the Graphs below, Instantaneous power was reported between 230W - 255W but the accumulated energy usage was reported as 325,7wh, which is physically not possible. I caputure the Power Value every two seconds and the connected microinverter has a peak of 300W.

Please share the URL I have to trigger for a downgrade to version 0.10.2, thx.

Storing the energy Values was one of the reasons I bought the PLUS devices, even ditched existing non Plus. Advertising shows "Power metering with data storage" knowing that the Non Plus does not have that feature and does not advertise the same I had the impression Values should be stored. HW was had been adapted with some durable Flash.

What does it actually mean, Is it just missing or will again not be possible cause of HW Limitation?

@Ivan Raykov: Both Graph show the accumulated energy, while on beta1 the issue was obious, 300W instantaneous power could never produce more that 300wh accumulated energy usage, but it was reported as 1200wh usage for one hour. Both Graph were directly caputured from "home.shelly.cloud".

@mircho.mirev: Does that translate to that all previous accumulated energy usage has been reported as to low. And starting from Beta2 this should be the real Value?

I'm measuring the earnings of my Mini Solar Plant, Beta1 messed up some of my statistics and it not possible to judge if the measurement is right with Beta2 as it strongly fluctating depending on the weather. Did you perform at least some basic reference measurements with a defined / calibrated load? Is it save to asume now that the accumulated energy usage is correct?

Thx & KR

Seems in 0.10.3-beta1 something with the measuring of the PowerConsumption is messed Up. I'm using it to monitor a Mirco PV with a maximum of 300W, so it should not pass 300Wh but it moved already pass 1200Wh. In Total it should have less than 1kwh as the Day just startet, but counter is already at 5kwh

First Graph with the new FW:

Second Graph before FW update how it should look like:

Edit: Flashed back to 0.10.2 fixed the issue, Values were around 5 times higher than they should be on 10.3..

Zitat von Quality Shock

Kann mich dem auch anschließen, stark Schwankende Spannung und gelegentlich Überspannungswarnung inkl. Abschaltung. Nach einem Neustart scheint es einigermaßen zu passen, 235V Multimeter vs 238V beim 1. Plus und 233V beim 2. Plus am selben Stromkreis.

Die Orange Linie ist ein 1PM dort ist alles gut, die blaue und grüne Linie PLUS 1 PM, Abschaltung sieht man gegen 16:28 und gegen 17:11 nach einem Neustart dann relativ stabil.

Nach etwa 12 Tagen war das Problem zurück, die Spannung ist nicht so oft wie letztes mal auf und ab gesprungen, scheint sich nach und nach aufzuschaukeln. Nach einem Neustart um ca. 15:28, hat es sich dann wieder verbessert, siehe Grafen:

Wenn man "Generic status update over MQTT" einschaltet, ist die Antwort umfangreicher, Spannung, Temperatur, Leistung & Verbrauch..

Same issue here, voltage was constantly flapping even causing over voltage detection und power off.

Orange line is a 1PM all good, blue and green line Plus 1PM, all connected to the same circuit, both plus suffering from the same issue. Please refer to the attached Graph around 16:28 overvoltage, at around 17:11 restart afterwards only very minor fluctuation < 1V. Had that for weeks and always wondered how it could differ so much.
