Simple CT-clamp monitor which is battery-powered or plugs in to 13A socket for ASHP monitoring
Hi all. I have a potentially silly question :). I've had a Daikin ASHP since 2009 but I've never known how much energy it uses. I would therefore like to get a CT-clamp based monitor to attach to its power cable (assuming I can find the right cable!). I'd like to start simple so ideally I want one that:
- Records daily / weekly usage - as long as I can look at a screen, look at the numbers and update a spreadsheet that's fine
- Doesn't need to be wired into the consumer unit, just a simple battery powered unit, or one with a simple 13A plug
In other words, while the multi-device consumer unit monitors from Shelly or Sue look great, I can't install them because I'm not an electrician.
I am struggling to find anything that fits the bill - do such devices exist?
Many thanks in advance for your help!
