How to reduce peak consumption (hems)

[dynamicdave]

Sorry - this might be a little bit off topic...

I'm using a PZEM-004T to monitor and report voltage/current/wattage and power-factor. My sensor is located on the main consumer panel, but I don't see any problem (apart from the cost) in using a number of these sensors [Edit] clamped around the live wire of key appliances.

Need to write one function that will return 3 values

Here's a screen-shot of my simple dashboard. [ScreenShot186] I'm using a PZEM-04 module with a split-ring current transformer feeding into a Wemos D1 Mini flashed with Tasmota that transmits to Node-RED via MQTT (very similar to your system). Here's a screen-shot of the NR flow. [ScreenShot184] And here's the flow-code that uses a dynamic band changer for the Power-gauge.

Since publishing the above posting, I've implemented a dynamic band changer for the 'current' gauge.
