New device: Shelly Plus RGBW PM

[nerdosity]

https://kb.shelly.cloud/knowledge-base/shelly-plus-rgbw-pm

Still hadn't be able to caught the button and the onboard LED pin. Can you build a firmware for this? I would gladly test it. Maybe if you enable configuration on safe GPIOs I can test which one is which.

Edit: advice me how to search for the PM device please

OTA Support should be easily to add. But first full Tasmota support should be done. @arendst Are you planning to buy one? Looks like a small job for you to add ;-)

Looks like a nice good made rgbw controller.

[TD-er]

No visible exposed pads at the bottom of the PCB? All vias look to be covered in soldermask and probing directly onto the ESP32 pins is rather tricky.

[arendst]

I'll order one and see if I can use PCBite to connect to it.

[nerdosity]

Yes, will post a lower photo of the downside. The usual header for shelly products is there.

Edit: Photo here

[arendst]

Still waiting for my order to arrive.

advice me how to search for the PM device please

From the pictures I see there is no specific PM device. They seem to use analog inputs to measure voltage and (total) current considering R001 at input. An Op-Amp (6331BP) is measuring voltage differences over R001 providing current used.

NOTE: Previous order cancelled due to long delivery time. Re-ordered at Shelly. TBC.

[arendst]

Almost there

[nerdosity]

Almost there

Was my pinout good?

[arendst]

Most. GPIO24 does not exist. It needs to be GPIO04 for the white channel

[nerdosity]

Did you checked if the inputs are galvanically insulated or not?

[TD-er]

Purely based on the pictures, I really doubt there will be any isolation.

[arendst]

Indeed, as can be seen on the pictures the inputs are connected to the ADC GPIOs using a resistor bridge. This bridge allows for connecting either a button or a 10k potentiometer. I have both working but currently ADC user configuration is very difficult using commands AdcParam for each GPIO as you need at least 7 of them for temperature, voltage, current and potentiometers/buttons. I'm adding a new command making more sense to operate.

Using latest dev branch you could play with Tasmota on Shelly Plus RGBW PM. See below info:

Do you think we could use something like this? Even RX TX and GPIO0 are not galvanically safe, right?

I sourced an Adafruit Qwiic Twist RGB encoder and now I can't use it 😔

[arendst]

That's a rotary encoder but NOT a 10k potentiometer. Not sure if that would work considering the fact that the device only supports analog inputs and I have never tested the rotary encoder that way.

[nerdosity]

Do you think it's possible to use the I2C device above on other pins? Or are they all not insulated and not 5v safe?

I'm talking about the Adafruit Qwiic Twist RGB, not the encoder pictured above.

[arendst]

The I2C device is currently not supported by Tasmota.

The rotary encoder on the other hand is supported. I've connected my rotary encoder to the Shelly Plus RGBW and it works "out-of-the-box" (to my suprise). Apparently the analog inputs also work fine if configured as normal Buton, Switch or Rotary Encoder.

[Angmar3019]

First of all, thank you for the great work here. I saw you already had success with the device and referenced the dev branch to test it. Since a new version has been released in the meantime, can I just flash it to test and then use one of your templates?

Do you know how long it will take until the device is fully supported like the other devices and a zip is available for download? Is there anything I can do to help with testing in the meantime?

[arendst]

Yes. v14.2.0 supports the Shelly Plus RGBW PM.

@Jason2866 how to go forward adding this to our mgos to tasmota site (if at all possible considering the latest FW changes of shelly denying our update procedure).

[Jason2866]

@Angmar3019 For adding support i need the Shelly intern device name. This is visible on the main Shelly Web page from the device. With this i can look at the Shelly update server to fetch a Shelly update zip for the device. In the Shelly update package all Infos and "parts" are there to build the convert zip. So please provide a screenshot.

PlusRGBWPM

[Angmar3019]

My Shelly was still delivered with an old firmware under v1.4.x, so I could still test the upgrade process via OTA if needed.

[Jason2866]

Update the Shelly firmware to latest available! else the device will get bricked!!!

To convert use this one https://github.com/tasmota/mgos32-to-tasmota32/releases/download/fw_v14/mgos32-to-tasmota32-PlusRGBWPM.zip for OTA convert of the Shelly RGBWPM. Follow the convert process as described. This version already takes care of the changes in newest Shelly firmware.

[Angmar3019]

Many thanks for the advice and the new package. I will test it directly and give you feedback if it works.

[Jason2866]

Mandantory is the Autoconfiguration step!!! Else you end in a bricked device! The device is already listed in the menu.

[Angmar3019]

Great that is now the second device that has been successfully converted to tasmota with your help. Everything, including the memory expansion, worked perfectly. I have also tested all inputs and outputs with an LED strip and buttons and they all work.

Unfortunately the template that was included in your package and the one that @arendst has provided shows the wrong temperature for me.

The screenshot shows the button template since the wattage and voltage are also read incorrectly in my case.

[arendst]

In addition to the template you'll need a lot of other commands.
