I’m late coming to this thread, but interesting news, thanks. I’m now living somewhere with european wiring, no ring main but lots of radial circuits to monitor, so more CTs would be welcome.
One small point - the only problem I’ve had with a 2015 vintage V3 has been the 3.5mm CT sockets not making good contact with the plugs (several times!) Cleaning and rotating them fixes the problem. In an ideal world they’d be gold plated or have a wetting voltage. Are the blue sockets in the photos a better quality than the V3 black ones?
thanks
Derek
