Shelly Plus Plug S - ESPHOME

Hi,
many thankes for the PinOut Points.
My Shells Plus Plug S ist defekt after 10 Days. There is nothing of reaktion at the device.
No reset ist possible, also is no power betwen GND and 3,3Volt.
Is there any to find out, ore some poit to check?

How did you open the plug?
Mine has no screws like the older models…

My have them inside contact holes…

It is one screw, and it is placed in the hole for “ground”. You’ll need a narrow and long screwdriver for it.

I’ll be trying the pinout flash soon, cause my new ESPHome firmware gets uploaded but the plug is not booting with the new firmware version 🥲

Hmm… this solution did not work for me.
First I tried to migrate via the software way. Migrated from Shelly Software to tasmota is easy. But I was not able to migrate from tasmota to ESPHome. Tried it the hole day along.
So I decided to open this thing and but the needles on it. I flashed with esptools on a raspberry. (tig's Blog)

The software said that the bin file is copied correct. But the plug is dead. I tried a second one. Also dead.

No reaction if I put 3,3 Volt and Ground directly on the pins. No reaction if I put in the wall outlet.
Oh no, I killed my two plugs. :frowning:

Any ideas? Maybe it is better to buy the ATHOM plugs with pre flashed ESPHome?

Found the solution in this thread: Guide for flashing ESPHome firmware with esptools on Linux

If the firmware file doesn’t end on “-factory.bin” it is likely not the modern version. If you flash the legacy version, the ESP will get stuck in a boot loop. I guess the difference between modern and legacy is, that legacy comes without a bootloader, but I never really checked that.

So I get out the needles again an do all the procedure from beginn till the end - with success! The first plug is now on ESPHome. :slight_smile:

Weird,
had the opposite experience.
Flashed the tasmota and then the esphome in modern format, however I always received an error. As soon as I used the legacy one everything worked. All via GUI.
In between I also “bricked” one, which I had to revive via TTL and the only way I could achieve it was with the legacy esphome one I built and esphome-flasher. Was not able to flash via web.esphome.io and modern format.

BTW: was anyonoe able to use bluetooth proxy already? Gave it a try, after I found out that this needs to be flashed via TTL, however the plug seems to be stuck in a boot loop now.

Okay, that’s really weird. But good that it works now. :slight_smile:

I do not setup the proxy function now but I will do this to in the near future. I use this plug to monitor the washing machine. The goal is to get a device that holds the full intelligence and reports only the actual status as a text sensor to Home Assistant. My ESPHome software is now fully functional but the last thing to perfection is to connect a (bluetooth) door sensor directly to this plug.

Therefore I have to setup the bluetooth integration in the future. But first I have to find a native working bluetooth door sensor. The Xiaomi is not such a thing. Maybe the Shelly Blu will work.

So you already implemented and flashed esphome including the bluetooth part?
If so, mind sharing the bluetooth parts you used?
The unsuccesfull part I used to try was:

esp32_ble_tracker:
  scan_parameters:
    active: false

bluetooth_proxy:
  active: true

The needle setup looks pretty similar to mine here XD.
Will probably give the bluetooth part another try at the weekend.

Flashed the bluetooth component yesterday. The device is online but I am not able to check if the bluetooth works.

I used the exact same configuration as you posted, but disabled the web proxy in addition.

Flashed via OTA. Two things I found to be aware off:

  1. it is not the bluetooth component that require the flashing via wires, it is the change of the framework instead. Because the framework is the same as at my first flashing, I flashed this time via OTA.
  2. Disable webserver because there is a risk to run out of memory.

After flashing there was no new entity or device like “bt proxy” or so. My Shelly BLU Door is not delivered yet. Therefore I am not sure if it works fine but the software is installed. :slight_smile:

Ressources: Bluetooth Proxy — ESPHome

The ESP32 Platform component should be configured to use the esp-idfframework, as the arduino framework uses significantly more memory and performs poorly with the Bluetooth proxy enabled. When switching fromarduino to esp-idf, make sure to update the device with a serial cable as the partition table is different between the two frameworks as OTA Update Component updates will not change the partition table.

Good luck!

Thanks, no idea how I missed the part that says that only switching type needs the TTL flash…

However I just tested my second working shelly plus plug via ota flash (was esp-idf) and now it is “dead”:

No clue what is going on. I just added the parts I mentioned before and flashed . Without the BT part it worked.

Sorry, I can’t spot any difference in the important areas. :frowning:

There is a new version V2 without screw, I have no idea to open it for flashing it via serial cable: (


thanks for looking.

Will probably flash again without the bt parts

Yeah, the V2 don’t have a screw.

Might try it with a small drill, as I “bricked” mine.

You can still do the initial flash via converting to tasmota first, as mentioned above. So as long as you don’t brick it, there is no need to serial flash it.

How can I find out these values for bl0937? ( I have one plug by local bytes that I forgot to make note of the values before converting to esphome and now I can’t get super precise measurements)

  # Higher value gives lower watt readout
  current_res: "0.001"
  # Lower value gives lower voltage readout
  voltage_div: "1830"

I flashed Tasmota with GitHub - tasmota/mgos32-to-tasmota32: ESP32 Mongoose OS to Tasmota32 OTA Firmware Updates for Shelly and repartitioned to make one big app partition. Is it possible to flash ESPHome by using Tasmota web gui? Can I just build firmware and flash it in Tasmota gui?

No, not possible, since the partition scheme used is the Tasmota safeboot scheme. This partition scheme has only one OTA slot, the other slot used for the OTA updating is a factory partition slot fashed with a special (very small) Tasmota version just made doing the update job. So the partition scheme is totally different to the one used for esphome.
For OTA flashing esphome a convert Shelly to esphome update firmware needs to be written in Mongoose SDK. This tool has to do the repartitioning from Shelly scheme to esphome scheme and writes a new bootloader. The Shelly bootloader allows only signed firmwares.
Tasmota does this all right after boot when Autoconfig feature menu in Tasmota is used. The Autoconfig downloads a new bootloader and the Berry runtime Code to flash The new bootloader and writes the Tasmota Partition scheme. Without the Repl Berry included in Tasmota this tool would have not been possible with Tasmota.

Shelly raised the secure. The new convert tool is only compatible with Tasmota

But if I flashed Tasmota bootloader, it will accept all firmwares, not signed only? If yes, then I could flash ESPHome if partition scheme was ESPHome compatible?
