Hi,
I am currently using tasmota on a Delock 11827.
It works flawlessly, thanks for the amazing work.

I would like to monitor the power consumption of my boiler, but it is not using a electric socket; its cable goes directly to the electric cabined.

I have seen that there are inductive/EM clamp that can be used to monitor the current/voltage through a cable.

Are there any recommendations that work with tasmota?

Thanks

PZEM-004T works – there are examples

Thanks for your reply.
But it would need to modify the cable.
I was looking for something around the cable.

You can’t put a clamp around both cores of a cable – it only works around a single core – whether it’s a CT or Hall effect device.

In the ‘cabinet’ the live wire will come from a breaker as a single core – you can use a split core CT to fit round the cable without removing the wire (must still be done with the power off.

Thank you very much for this information, looks a bit too much for my capabilities

To be honest better looking at the Shelly EM (which will fit on a DIN rail) or putting a junction box in with a PZEM
