With its excellent wireless range and weatherproof design, this power meter is an essential addition to any multi-protocol smart home hub. You also need a CT clamp – the Mottram Labs module has been designed to work with the SCT-013-000 clamp. You will need an accurate meter to benchmark the device against it, and input the offset as a percentage in the Settings (Specific) menu. At the time of writing, Aeotec do not offer any HEM units that are compatible with Aussie standards.

It detects the energy flows of the PV system and transmits the excess energy data to the PV Power Manager AC•THOR, AC•THOR 9s. Also, are you checking the messages from your emonTx for validity - as well as the “OK” (which does not actually come from the emonTx itself), do you check the length? After seeing the introduction of the Energy section in Home Assistant, I wanted to get onboard with monitoring the homes electricity consumption. Fortunately someone in an electricians forum has a spare monitor which they are sending me so hopefully I’ll be able to identify the right cable and get some data out of it.This works for me, and having lurked on here for nearly 4 years and learned so much from you all, this was a chance to put back. What I do know is you want to be very very careful poking around in it as it could well still be live!

The device is still not yet officially supported in ZHA, but there is a custom quirk developed for it. And its intelligent clamps will report that energy use back to your control point, in watts or kilowatt-hours, and in real time, so you can see how much electricity you really use and when you use it. This means that it will not show any usage if you switch on only -for example- a led light of 9 Watt.

You need to have owner-level access on your portal, so you’re are able to download CSV sheets for your daily instantaneous power data for the inverter.

I do not have the device to test this (I gifted it in a reddit giveaway), but please add this to your Zigbee2MQTT configuration. That’s why we need the utility meter integration, to create a sum of consumed energy from those values.On the first image you can see the state before and after playing around with the CT, arranging things, etc. I can only think of some peculiar wire arrangement in the box above the test hook that influences measurements when the CT is placed in certain positions… I’m now using simple cloth clips for holding the CTs on the side to avoid future problems. You can use it to measure any cable but you need to separate it or the magnetic fields will cancel and you will not get a reading. There seems to be a negligible difference in their computed Wh totals for ~24 hours (about 170Wh), good. The user instructions from Aeotec are available here as the settings page is complicated to reflect the plethora of options on which group to report which clamp.

However, I’ve never seen these clamps on installation photos (even with expensive, brand ones) or live installed as a tight fit nor on a completely straight cable or far from other cables - on the contrary! Si votre installation est en triphasée, il faudra vous orienter vers le modèle avec les 3 transformateurs d'intensités.Highly recommend you check the device you purchase is compatible with the frequencies used in your setup. Once you have a wire with a known current on it you need to install your configuration on the D1 with the ‘calibrate-linear’ lines (56 – 58) commented out.
