How to measure the maximum power of an electrical circuit in Zigbee? Shelly EM?

Configuration
1

Hello,

I am looking to measure the maximum weekly power drawn on a specific circuit in my electrical panel.

I know that to measure consumption in kWh, you can use a pulse counter module.

But to track the evolution of the power drawn and know the maximum value of the day, can the Shelly Em do this?

I have a Zigbee Zigate dongle.

If the Shelly Em can do this via Wi-Fi,

What happens if the Wi-Fi connection is lost for 2 hours? Will the readings from these two hours be lost, or will the Shelly resynchronize when the connection is restored?

I am rather looking for something equivalent in Zigbee / or Ethernet / or USB to connect to the Pi at the same price range as the Shelly.

If you have any ideas, I am interested :slight_smile:

Have a nice evening

Do you have Shelly Em documentation? I think it will answer your question about the reading. I hope this kind of solution has a cache to store data for at least 24 hours, for example.

For me, the best plan is the Zigbee TIC if you have a Linky.

But it’s dead for the specific part.

Which part do you want to measure? Electric heating?

Otherwise, you have this on DIN rail

Hello,

I am trying to use the LIXEE - TIC to Zigbee 3.0 Module for LINKY meter

However, it is not supported by Zigbee2MQTT.

I am a beginner, can someone help me?

Thanks in advance

It will arrive quickly

How long did you get it after your order?

6

Quite fast, I think it took a week. I ordered after Pierre Gilles’ email, using the sponsored links.
I ordered a lot of other Zigbee devices to test. I will try the others and report any bugs if I find any.

7

I am not very familiar with this type of device. Once the Zlinky support is done, will there be any manipulation I need to do on my side?

8

Yes, we will have to see what we recover on Gladys’ side. There will surely be modifications to make as the device is really specific. As a user, you will just need to refresh the device discovery.

OK thanks for the info. I will wait to see when the system will be updated

Hello, I just looked at the site: https://github.com/fairecasoimeme/Zlinky_TIC
It talks about « Firmware Update (not OTA) Â»,

I don’t know if you know or if you can help me. Do you think I should flash the module so that it is recognized by Zigbee2MQTT?
Have a nice day

I received mine

We’ll have work to do for the TIC.

No feature is detected.

I am not a programmer, however tell me if I can do something to help?

Hello, thank you for the feedback

Yes indeed it is really to measure a specific circuit (not the main meter)

Interesting for the Tuya meter from AliExpress but is the gateway sold separately necessary? Any feedback on this product?

Regarding the Climax, I couldn’t find where to buy it?

14

I believe Tuya is Zigbee.

15

Yes in my case the Tuya is only Zigbee.

16

OK cool thanks for the feedback

Regarding the tuya Zigbee, how often can we get a power reading in seconds?

According to Gladys’ logs, she receives a value from my desk outlet every minute. So 60x per hour and 1440 values per day!
In my case, that’s way more than necessary.
