Hello, I am wondering if there is a wattmeter like the Sonoff POW but with a non-intrusive clamp or ring? Ideally a device that can be inserted with DIN Rail and > 32 Amps Something like that but with Espurna: Thanks to all in advance

your linked device can possibly be used with espuna, i have a similar device in use with tasmota, so erspurna should be possible also... see here for details...

Thanks @krikk, I learned a lot from this post but unfortunately, Espurna doesn't support the MCU V9821 so I had to use Tasmota. Thx

See my post #2277 and others using the PZEM-004T. https://www.amazon.co.uk/peng-PZEM-004T-Multimeter-Split-Core-Transformer/dp/B0842NWC1Q/

I used a Wemos D1 mini and 240V to 3V converter inside a double pattress box and fitted the current transformer around the consumer unit neutral. You obviously need to know what you are doing with mains electricity and the dangers involved.
