How to display consumption and charging processes on Shelly

[SunnaBu]

Description

Hello, I'm using two Shelly devices in series to control an infrared heater ("Bad Heizung"). Why two? The first Shelly 1PM measures power consumption and is always set to ON. Downstream (in series) is the temperature-controlled switch from the infrared heater manufacturer (which must always be powered on), followed by the second Shelly (without a power meter) for switching via evcc. Both Shelly devices are configured in evcc and are essentially working correctly. While the heater is running, I can see the current power consumption, but the actual power consumption isn't displayed, and consequently, there's no charging indicator. The evcc heatig device ist still telling "Ready. Waiting for heater.", even if heating is in progress. My AVM DECT sockets ("EG Heizung" for comparison) displays everything perfectly.
Based on the config, could someone perhaps give me a tip on whether and how this can be optimized/corrected with the Shelly devices? I'd be happy to configure them again via YAML if necessary.
Thanks in advance for any helpful tips.
Best Regards, Ralf

It always happens the same way, as described.

Das liegt daran, dass die Fritz-Steckdosen auch messen können, dann funktioniert positive Standbypower.
Stell mal beim Shelly-Charger Standbypower auf -1.

Wenn Fritz-Charger und Fritz-Meter dasselbe Gerät sind, brauchst du das Meter nicht. (Sieht man leider nicht, weil uri anonymisiert wird)

Danke für die schnelle Antwort. Bei Standbypower auf -1 habe ich nun leider den Effekt, dass immer Laden angezeigt wird, da der Temp-Regler der IR-Heizung ca. 0,8 - 0,9 W zieht.
Ich denke aber, dass ist der deutlich elegantere Weg, da ich nun die geladene Energie sehen kann. Wenn es noch einen Weg gibt, zwischen Standby und Laden zu differenzieren, wäre super.
Nochmal vielen Dank für den Tipp.

Bei negativer Standbypower wird "Laden aktiv" immer dann angezeigt, wenn der Schalter eingeschaltet ist. Das hat nichts mit der gemessenen Leistung zu tun.
Der eleganteste Weg wäre ein Shelly, der schalten und messen kann (analog Fritz).
