Hello,
I have problem to use shelly 3 pro EM sensors in HA Energy. I can't see my sensors in the list. When I look at "states'" of them, they are not declared "Energy". Can someone point me to the solution please ?
Thank you

Which sensors in which list are not showing up

#

Integrated via the Shelly integration? All up to date? Then the entities should just be good to use.

#

I integrate them per the shelly auto integration. But they are not rated as "Energy" as shown in the screenshot below :

#

#

from the HA doc, the sensor must be set to "Energy" in "device_class", which is clearly not.

#

Do I need to create a new sensor that reflect this one, or should I change the current one ?

#

mine showed up with the shelly name

#

How does yours look under devices?

past anvil Jul 3, 2025, 1:50 PM

#

I changed the name in Shelly web GUI and also set the Shelly in "monophase" rather than "triphase"

oblique jay Jul 3, 2025, 1:50 PM

#

go under entities... are any of them disabled?

past anvil Jul 3, 2025, 1:51 PM

#

nop

oblique jay Jul 3, 2025, 1:52 PM

#

misspoke... click on each device and look for disabled entities

#

oblique jay Jul 3, 2025, 1:52 PM

#

I had to manually enable some of my sensor entities

#

click on them one by one

past anvil Jul 3, 2025, 1:53 PM

#

in Shelly webconfig ?

oblique jay Jul 3, 2025, 1:53 PM

#

no

#

under devices

#

#

did you have to update the firmware on the shelly before you connected it to HA?

past anvil Jul 3, 2025, 1:56 PM

#

I have the lastest firmware and all required sensaros are activated in HA config

#

The real problem is the device_class, really nothing else

oblique jay Jul 3, 2025, 1:57 PM

#

I thought that with mine too, but apparently i put the CT clamp backwards

past anvil Jul 3, 2025, 1:58 PM

#

definitively not 😉

#

what device_class use your shelly power sensors in HA ?

#

power or energy ?

oblique jay Jul 3, 2025, 1:59 PM

#

did you filter for device_class: energy?

past anvil Jul 3, 2025, 1:59 PM

#

this can be see in Developer Tools > States

oblique jay Jul 3, 2025, 1:59 PM

#

#

maybe the renaming you did, messed up something?

past anvil Jul 3, 2025, 2:00 PM

#

That's it

#

probably the renaming have something to do with my problem

#

does the name in Shelly webGUI have something special in the name ?

oblique jay Jul 3, 2025, 2:02 PM

#

i connected to my shelly with the IP address

past anvil Jul 3, 2025, 2:02 PM

#

Same

unborn pumice Jul 3, 2025, 2:15 PM

#

I don't yet see the issue

The power sensors obviously measure power and not energy

#

The pro em3 shows up as one device for each phase as well as one for the entire unit which has the aggregated values which you should be using for the energy dashboard

#

#

You should see them both on the combined device

past anvil Jul 3, 2025, 2:26 PM

#

I can't find this. I think that when one rename Shelly Channels at Sheely side (using the Shelly GUI), it break the HA integration.

unborn pumice Jul 3, 2025, 2:46 PM

#

It shouldnt really. Like why were it for energy and not power

#

Shelly likely even reports the aggregate dedicated as it gets displayed in their ui

#

You may want to consider reverting to defaults and if that brings it back then file an issue against the integration

mellow pelican Jul 3, 2025, 2:59 PM

#

But did you go to the device? So Settings => Devices & services => Devices (tab) => look for the Shelly and click it.
There you have a full page with info about the device including all entities it provides.

#

And indeed, don't confuse power and energy 🙂

past anvil Jul 3, 2025, 3:30 PM

#

will try

#

I deleted the 3PRO EM in HA, reverted it default (Shelly) then add it again in HA and the same result appear. It device_class is power, so it can not be added in Energy as a "electricity income" to my home

unborn pumice Jul 3, 2025, 3:50 PM

#

The device class isn't wrong, you are looking at the wrong sensor

#

You need a sensor reporting energy

#

Have a look at the device as septillion described

oblique jay Jul 3, 2025, 4:03 PM

#

yeah if you click on it under devices.. you should see all the sensors it has...
eg

#

there should be two with "energy" in the name

#

past anvil Jul 3, 2025, 4:17 PM

#

Yep, but there is NO sensor reporting Energy from the 3PRO EM when using Sheely integration for this device.

#

Anyway, I create a template with the correct device_class that report the same information from the sensor I need 😉

unborn pumice Jul 3, 2025, 4:37 PM

#

It seems very odd that it wouldn't report values which it does for other people.

#

Be aware that power isn't the same as energy so you setting a different device class doesn't actually do anything useful

past anvil Jul 3, 2025, 4:53 PM

#

thanks. Anyway I have to work with HA to get more knowledge about it. It's a good start...

#

And also I have to check Shelly as it don't report the good infos... The power diplayed is far from reality.

#

it currently report 780W from my solar pannels when OpenDTU claim 541W

mellow pelican Jul 3, 2025, 10:14 PM

#

past anvil Anyway, I create a template with the correct device_class that report the same i...

Impossible to just use the other entiry, as energy is not power.

Could you share a screenshot of the device page of the Shelly?

Hi, I installed a Shelly EM Gen3 yesterday and had the same issue. The solution is to create a helper of integration type that uses the power sensor from the Shelly and converts it into 'energy', that's power over time. I'll pass the link to the docs in a while. It works now fine. Another issue is the type of calculation. I use trapezoidal as recommended but I'm seeing that some people here recommends left

Here is the explanation, not very clear, IMHO 😅
