  • $9.99 - Aeon Labs DSB09104-ZWUS Z-Wave Home Energy Monitor

    Just ran up on this. Might be a good deal. Might be a piece of trash. I know nothing about this specific product or the supplier. Just passing along a potentially good deal. On amazon it is $59.99 and this site has it for $9.99

    I use 4 of them and they've been working well for me. Amazon used to have them for around $20, so this is a great deal.

      Here we are using one to monitor when the electric clothes dryer is running, an event tells us when the clothes are done.
      Great WAF approval.

          How do use it on a dryer? Are you only using one of the clamps?

            Yes, you can only use one clamp. I have mine installed at the electrical panel. That way you can use the other clamp for another appliance/circuit.

              My dryer is 240v so it takes both clamps.

                  Perhaps there are some dryers like this, but all the ones I've seen have 240V heating elements so none of this current flows on the neutral. Only the 120V components (controls, motor, etc) typically. Same with electric ranges, etc.

                    Good point. There are none like that. Will go have my coffee now :-)

                    Having said that, to setup notification when a dryer is done, you only need to know when the motor is running, not when the elements are on. Therefore a single clamp (either on the neutral or the hot leg that carries the current for the motor) would still suffice. If you want to measure power consumption, you would need both.

                      In for one. I'll try it out on my panelboard incoming main. I was planning on picking up a Rainforest Eagle Monitor to talk to my smart meter, but at $10, I can't pass this up.

                        I run this on only one leg of the 240 for my dryer (just one clamp). I don't care about monitoring the energy accurately, just that something is happening. The leg I monitor goes to 0 when not used and at least over 100 watts when running. So I build my events based off that. It has been very reliable. I did it at the dryer personally, but I like the idea of doing it at the panel and using the other clamp to monitor something else... like the washer

                          If I monitor at the washer/dryer which are both 110v, I could use one clamp for the washer, the other for the dryer to just get the on/off status?

                            Yes - that should work. Both legs are reported separately.

                              Yes, but it may be easier at the panel as you would need to split the conductors of the power cables for the washer and dryer, or install the clamps inside them. The clamp can't be placed around the whole cable as the current in the neutral flows in the opposite direction of the current in the hot so they cancel each other out when measured with a clamp-on current tester.

                              Cheers
