No sensor readings from Aeon HEM v1

[Smartphi]

Yes i use both, the first one on washer and dryer m, and the second one for refrigerator and microwave.

Maybe you have a bad HEM unit. I haven’t touch firmware, it has whatever firmware came loaded.

I have never upgraded the firmware on my Aeon HEM v1’s ( I have two of them, and both work fine.)

The HEM seems to only send data when there is a change detected in the power being monitored. If you can, try plugging a lamp or hair-dryer into your ‘split jumper cable’ so you can turn a device on and off. This should cause values to be sent.

I use my HEM to monitor my washer and dryer using this DTH (a slight tweak of Mike Maxwell’s)

Aeon Home Energy Meter v1 -- Read Clamps Separately

I am still using a very old version of Mike Maxwell’s DTH for the Aeon HEM v1 with no issues. I my case, I have a very well behaved washer and dryer, in that they both always stay above a certain wattage when running, and always drop below a simple threshold when the cycle completes. It looks like the DTH you’re using may be much more sophisticated these days, which may be leading to the confusion. Here is the version I have been using for years with zero issues. Make sure you click “Configure” after switching to this DTH as it will send a special configuration to the Aeon HEM v1 to send independent wattages for each clamp.

Thanks for the replies @ogiewon and @Smartphi.

Quick sanity check: In steady state, is the red LED supposed to be on or off?

I thought it was supposed to blink until it was paired and then go off, but in my testing tonight I have not seen the red LED turn off. I have not seen any configure messages fly by either, so I wonder if it finally stopped working 100%.

My RED LED is illuminated all of the time once paired.

Success!

At the recommendation of another troubleshooting thread (Troubleshooting Aeon Labs Home Energy Meter v1), I performed a Z-Wave exclusion and re-pair. One of my (now many) device handlers was picked by default afterwards and appears to be reporting in lock step with my turning a lamp on and off.

Prior to that, I also removed the device from the API and repaired, without success. My LED is now solid. I can’t explain why it was going off before the removal/exclusions.

I have one parting question: Do the K/L markings on the clamps have any implications for the dual clamp users? In my limited testing, I have clamps oriented both ways on the same wire and they are reporting within 1 watt of each other. See these links for what I am referring to:

Thanks for everyone’s help.
