I've had a clip on meter for many years.

I capture the XML data stream mine produces and log it. Then have a
bit of PHP that'll plot a graph of consumption for a given day.

Then there is the useful life of the kit. I have only had 3 years
from this unit:

https://www.eco-eye.com/product-monitor-solar-smartpv

It enabled me to keep an eye on my PV system and usage. I liked
being able to glance at the display and also look at the real
time graph on my PC.

Getting a good signal for the remote display can be tricky, and I
don't have thick walls or a long distance to cope with.

The accuracy was generally acceptable, though it sometimes seemed
to imagine PV generation at night, or spells of zero usage.

However, it has now stopped working completely, and shows no
signal even if I hold it right next to the transmitter. I might
try changing channels again, but I think it is probably dead. :-(

Maybe if I am looking to replace this, I might look for something
that will do both the immersion trick and provide monitoring
data, but it does make me pessimistic about payback/ life.
