I received my Aeon HEM v1 from Amazon, paired it with my ST v2 hub, but have not successfully gotten ANY readings out of it consistently.
I plan to use it for washer and dryer notifications, so I have primarily tried “dual clamp” DTHs which support reading current from each sensor individually. I have also tried jscgs350’s DTH, as it seems like the most frequently updated, although I am unsure if supports reading clamps individually.
Where do you have it installed? If it’s on a cable for your washer or dryer then the hot and neutral must be separated in the cord and a clamp goes around one wire only otherwise you get a cancelled-out reading of zero.
And if you have an electric 220V dryer then see here for more help:
Best option if you can. In my case there is not enough room in my panel on the individual breaker circuits to get a clamp on the wire. No problem on the main legs in - I just can’t use the HEM on any individual circuit.
I started to go for a HEM on the washer and dryer and ended-up using smart outlets with energy monitoring instead. Looks a bit cleaner too.
This is likely your problem. You have both ground and hot in the same clamp so they are cancelling each other out. 1 wire per clamp. 1 clamp on the hot wire and 1 clamp on the neutral.
I only use these on 220 circuits, but that is how I have hooked up every one. The read separately for washer and dryer with the same HEM DTH, you put 1 clamp on the hot for washer and 1 clamp on the hot for dryer.
Thank you for the response. I still have not solved this issue.
I will be happy to be wrong, but neutral/white/groundED and hot/black in the same clamp will “cancel” but green/groundING and either should not, because (unless there is a short) no current flows in it to cancel anything.
In any case, this is a “dual clamp” DTH that reads each clamp independently, and only one clamp has two wires (black/green). The other (white only) should be producing its own reading.
I appreciate the help. Does anyone have any other suggestions?
Have you ever looked inside your electric panel?
The green/bare ground and the white neutral both go to the same lugs. So either with the black or red hot will complete the circuit.
Time to spend some time on YouTube or hire yourself an electrician before you get hurt.
@ogiewon - Thanks for the help. Indeed I have pressed configure after switching DTH and I am running on USB power. At one point I was also using batteries but I have since removed them, with no change in behavior.
Are you running firmware 3.64 or 3.60? How quickly should I see a sensor reading on the app? Within 1 minute? I see that some DTH have settings to poll every 15 or 30 seconds, but maybe this doesn’t mean what I think it does.
