Shelly PRO EM 50 - ADE 7953 IRQ

[Massimo65]

Good morning,
I'm a very satisfied tasmota user. I tried to configure the new Shelly PRO EM 50 without success. The configuration for this device is available on the EspHome website; I tried installing it, and it worked fine.
I then tried to reproduce the same configuration in tasmota, but without success. I believe the problem is assigning the ADE7953 IRQ, as there's no IRQ value for ESP32 and I2C sensors, such as 2 for ESP8266.
Can you help me? Are my observations correct?
Thank you and best regards.

Not clear what exactly you mean when you say

Hi,

This is the configuration reported in xnrg_07_ade7953.ino

According to Esphome, the shelly PRO EM 50 has the following configuration:

GPIO 4 | ADE7953 IRQ
GPIO 13 | I2C SCL
GPIO 15 | I2C SDA
GPIO 16 | ADE7953 RESET (active low)

But I can't find a configuration for ESP32 with Current measurement device CT.
The only configuration with Current measurement device CT is 2, but it's for the ESP8266.
I hope I was clear, and I apologize for my poor English.
Thank you for your support, and I remain available for any further clarification.

What happens if you select option 2 (IRQ 2)? Does it work?

[Massimo65]

I tried, but it doesn't work. If it helps, I'll send you a photo of the setup, but I can't right now. I'll send it to you this evening.

Anyway, thanks.

OK. I made some changes to the ADE7953 driver.

Pls try again using IRQ option 2 and report back (this evening).

Hi,
the modification seems to be working. I'll do more in-depth testing in the next few days. In the meantime, I've attached the current configuration.

This is the template:

{"NAME":"Shelly Pro EM-50","ARCH":"ESP32","GPIO":[0,0,224,0,3457,0,0,0,0,608,544,640,9472,0,5600,0,0,0,0,5568,0,0,0,0,0,0,0,0,5536,0,0,32,4736,0,0,0],"FLAG":0,"BASE":1}

Of course I had to calibrate using a 100W bulb. The calibration results are these:

Currentcal: 8850
Voltagecal: 32690
Powercal: 1715

Thanks for your support, I look forward to your comments.
Naturally, if you need any tests or information, I'm available.
Best regards

I received my Shelly Pro EM-50 too and can verify your template works fine. Also ethernet just works.

For completeness this is the correct template:

{"NAME":"Shelly Pro EM-50","ARCH":"ESP32","GPIO":[0,0,224,0,3457,0,0,0,0,608,544,640,9472,0,5600,0,0,0,0,5568,0,0,0,0,0,0,0,0,5536,0,0,32,4736,0,0,0],"FLAG":0,"BASE":1,"CMND":"AdcGpio36 10000,10000,3350"}

it includes the temperature parameters too.

I wasn't able to use the Shelly calibration data which is stored in the filesystem like

{"factory":{"calib":{"hardware_checked":true,"done":true,"etalon":"3CE90E6EA344","gains":{"avgain":4770740,"bvgain":4768757,"aigain":4198690,"bigain":4220953,"awgain":3637937,"bwgain":3641583,"phcala":895,"phcalb":895}}}}

Using the plain values doesn't calibrate Tasmota very well. So just use the energy calibration as you did and documented https://tasmota.github.io/docs/Power-Monitoring-Calibration/
