The 22kW 3-phase zappi come with 3 CTs as standard. 65V, as the output of the CT will vary from -1V to +1V. Dec 19, 2018 · sparkydave (🇦🇺 Dave) December 19, 2018, 2:50am 2. Sure enough within a few minutes of receiving it and plugging in a D1 Mini and CT clamp I had energy monitoring in HA. Current (amps) = power (watts)/ voltage (volts) And applying this to a template. RPICT8 - 8 CT; Note, if your device is not listed here you can create a json mapping file - Please look at the examples in the config/device-mapping directory. RPICT7V1_v2. Have a look at these plots: The first blue plot is similar to what comes out of the CT. First, setup an ADS1115 Hub for your ADS1115 sensor and then use this sensor platform to create individual sensors that will report the voltage to Home Ct clamp for home assistant with esp32. Once installed, you will need to restart Home Assistant before you can configure it, so do that using the option in Developer Tools. Jul 10, 2023 · supersebbo: Your energy monitor pictured is just a CT clamp in disguise. Well, I am wrong, it’s $124, $164 but still for 16cT’s I think it’s cheaper then $18 for one of the other CT’s. Energy Tracking - CT Clamp Current Sensor. The main motivation behind this was to get real-time data from the inverter, particularly the grid in/out readings from the CT clamp so that I can maximise self-use. While the sonoff POW will give you power useage, you can convert this to current using the below formula. tom_l October 11, 2019, 7:13am 2. I would like the same thing, but compatible with HA: - Battery powered sensor box, so it can be left in the electric meter cabinet (where ironicly it can't be plugged in) - Using a CT clamp instead of being wired in, as it's a rented house. 5mm/3. Jun 20, 2024 · Values from console mapping to values from the kill-a-watt: - 0. It can easily be hooked up to an ESP8266 or ESP32 to wirelessly transmit ene…. KruseLuds June 20, 2024, 7:35pm 2. then i used linear filter to calibrate for that value. I am considering going with Esp32 and CT sensor Clamp since Sense Energy is expensive. The power cables were preconnected to the device, all that remained was to screw in the antenna and the clamps. 1. I have tried 2 May 21, 2024 · I changed the rates to every 30 seconds, but still varies. CircuitSetup – 15 Apr 19. The Shelly EM user manual is here. Currently I have an old ferraris-counter which I tried to log with an tcrt5000 - but it is unreliable as hell 😃 To have more precise values i would like to use CT-Clamps for this - but I did only find guides for single phase monitoring. but first i hooked them up all on one cable and ran a dryer with 1400w. 4 running on a Raspberry Pi 4. Unfortunately they’re too small to fit around the mains in my hydro panel (50A and 120A are the same size) so I bought the standard blue 120A clamps… but calibration is wrong so the Shelly readings are wrong, making the results wrong in Home Assistant. The breakers range from 50-25 amps. zappi & eddi come with one wired CT clamp as standard. 010 corresponding to 0. But I can’t get a correct reading from the sensor. Home Assistant is open source home automation that puts local control and privacy first. Contribute to gnlgrim/Ctclamphomeassistant development by creating an account on GitHub. I have connected 3. template: - sensor: - name: "Mains Power In W". Hello i need help, if i may ask, i have a Shelly Em to measure my consumption and works fine, and i have a sub panel separated with an Ats Switch, when the Sub-panel is On using the Inverter, the readings on the main panel became unstable jumping from negative to positive values every Bubble Card is out! It's a new card collection for Home Assistant that allows you to create animated pop-ups. Got it working and it gives pretty expected results. However, it wasn’t clear to me how to get the data from my house into the tool. lj pu ux ux ua lk tv iz ja nn
