Hey Boys, i can't wait to flash tasmota onto it either :-) Cheers and Thx! |

Why would you think that there are only "boys" involved in the Tasmota project? |

The accessible GPIO pins are found here: 1: esp_debug_uart CAUTION! High voltage on the add-on interface when the Device is powered! |

I guess I need to test disabling serial logging to see if that solves that issue… |

Anyway: thanks for providing that template! Any Ideas about the LED? |

OK - serial logging is disabled (automatically - possibly because of my automation - not sure...), so it should not trigger issues with I2C... Which is still used and the device is detected: so energy (taken from real file - not rule) is loaded. Unfortunately there is nothing obvious in the logs (4 - more debug) that I can see that would indicate an issue when rebooting the device... |

I've got my hands on multiple units. A few ones are early access (prototypes) and factory calibrated for 400A. I can confirm that all samples I have (that are not factory calibrated) contain the same data structure at {

I have not yet tried to calibrate any of the units. I'll try flashing a non-calibrated on with Tasmota this week. |

As for rebooting: I did now enable Debugging ( and here the filtered output: On initial power on: and after a reboot: so there is nothing that is found besides the device on i2c! |

so I have added a debug for ininit: And repowered the device (now taken from web console): and on (note that I had to increase the line buffer as well to get those early log lines) So in the end: for some reason on power up i2c detects the device and then the Driver init (Ade7880Init) is called. I do not have a deep understanding of the initialization process in tasmota, so someone with more knowledge in this area needs to look into this (or at least give a good hint where to look exactly, so that more diagnostics can get added)... |

ok, so I found something else by instrumenting the dispatcher function: PowerOn: On restart: At a loss where it is going wrong... |

And I have to admit: I am not sure if I can open that expensive device without breaking the case rendering it unusable... |

So I got brave/stupid and opened it up (4 clamps - 2 at the bottom/DIN Rail and 2 at the top). I shall try tracing the LED as well - (the Resistors R45-47 are routed via several vias to the ESP - details to follow) |

in the meantime: the RTC chip is a AIP8563! |

So I was too brave! The device is no longer 100% happy - wifi does not work any longer... But I got a few pointers:
And as said: my best guess is now that there is no GPIO for reset of the ADE7880 |

So it works on first boot but not on reset? Why is the reset of the ADE7880 needed? |

Hello, please are there any update for support Shelly Pro 3EM? I would love to use smaller 50A transformers, so need to use alternative firmware (Tasmota) and calibrate manually. Thanks. |

Hi everybody,
is the Shelly Pro 3EM already supported?
If not will it be possible to run tasmota on it?
Controller is a ESP32 DOWD Q6
