Wanted - a redundant emonTx V3

[Robert.Wall]

John Cantor wants one that’s no longer needed.

Any old emontxV3 no longer in use?

I am trying to do simple monitoring of badly set-up Eco4 heat pumps. Trying to do on a shoestring, and only CT and temperatures. An old emontxV3 would do the trick. Any second hand ones about? Just seeing input power and flow/return temperatures can tell a great deal about the systems health
