Pass through socket or simple clamp showing power being used

[NotebookNewport]

hi
I have a tumble dryer in an external shed running off a cable. It’s temp as having house gutted. Anyway, when it stops I have no way of knowing. Is there some indicator I can attach house side to tell me when it’s finished?
Thanks

If it is plugged in to a socket in the house, then a cheapo plug-in 'energy monitor' (which is 'pass through') will tell you if it is drawing any current.

Ok ... who sells them and what price?

'Everyone' sells them! Whilst I do not necessarily buying a very cheap one from eBay, when I did an eBay search for "plug-in energy monitor", I got plenty of hits, the first of which was this one (click here) , at £7.99.

Ok. I see the type you are in about. Thanks

Don't all tumble-driers have a built in timer?
My mum's, which I inherited, had a simple clockwork type thing in the 70's
My washer drier has a push button that adds time in units. Just lok at your watch when you turn it on.

I presume that the OP's dryer does 'stop' after a set period of time - but he/she seems to want a remote indication of when it has stopped.

Er.... 20 mins after you set the timer for 20 mins?

Well, ours usually runs for 60 or 90 minutes but, yes, a watch/clock and a slight bit of memory ought to do the trick. I was not 'sympathising' with the OP's request, but was merely stating what he had asked!

Kind Regards, John

I do the same, put a battery on charge using energy monitor, it goes through stages 3.8A, 3A, 0.8A 0.1A and off which show on energy monitor as 54W, 44W, 14W, 2W and nearly zero so in my case with a wifi internet connected model I can see where every I am as long as 3G signal what stage battery charger has reached.

With tumble drier you will get around 2kW then around 250W when in cooling stage then zero once complete. With a humidity sensor clearly time varies so yes would work OK.

I also use mine to test fridge/freezer from time to time, a little maths involved, but over a week it records time and power used, so divide power by hours and times by 8760 (hours in a year) and we have watt/hours per year divide by 1000 and kWh per year, if some where near what adverts say it should use OK, if well over then further tests is temperature set correctly or has insulation failed.

It is about the only use for the devices, as does not matter how much my TV uses I am still watching TV and anyway written on the plate.

Depends on the tumble drier. A lot of modern ones, including mine, base the switch off point on measured moisture level, not on time.
