Aeotec Home Energy Meter Gen5, Z-Wave Plus Smart Electricity Usage Monitor, Report Real Time Power Consumption, 1 Clamp, Detect up to 60 amps for Single Phase System

Product Information

You also do not have rcd protection in that fuse box, the fuses are there to protect the cables, not people, so be very careful with your electrics in general, fuses might not disconnect / wont disconnect in time if you get a shock and you could be electrocuted.

To pair it, press and hold the button on the module for ~5seconds until the red LED starts blinking. Again, I can understand that moving the CT might cause a slight change especially if the two halves of the core moved and added, altered or removed a small air gap, but I cannot see how that could repeat on alternate readings. Some of the code was just to see visually what’s going on during the calibration process (easier to look at on a dashboard compared to the log file). Flow temp is 55C with weather modulation - it's expensive but works even during the Beast from the East.But when I initially did the circuit I did omit the burden resistor and I wonder If I’ve damaged the ESP32. The clamp detects one load / circuit and reports the real-time power consumption to your Z-Wave smart home control gateway. Select the Tuya Clamp Meter Energy Entity as an Input Sensor and set the meter reset cycle to Monthly.

Once you reach the point in monitoring your home’s energy usage with Home Assistant, you can consider yourself an advanced user.This one has two terminals which are not used at all, so it’s being recycled for something else, possibly a garage door or a curtain module. The case of the module looks and feels really familiar, Chinese manufacturer tend to reuse cases like these for many devices. Also its designed to work on your meter tails, which are 16mm or 25mm cables near your electric meter or main fuse, trying to measure very small currents will probably not work so well e. This device adopts open-loop current transformer, which can be easily connected to the device to be tested.

I’ve attempted to replicate this project using ESP32 and SCT-013-000 (100A clamp without the burden resistor.To test the accuracy of this single clamp power meter by Tuya, I decided to test it against a high quality flood light rated at 100watts. Quick update on this: an acquaintance on an electrician forum sent me an OWL but s got the wrong sensor, so on the look out for the right one. Simple, safe installation at the meter – can also be installed inside a consumer unit by a qualified electrician. If the spikes are coming in as valid, that seems to rule out any possibility of corruption in transmission or in the logging process. If your clamp is not tight around your cable - it will not measure accurately, equally if the cable does not pass through your clamp at 90degrees to the ferrite “core” - it may not be accurate.
