Energy meter integration with HA

Hardware
#5

Shelly has two devices that will monitor your consumption, Shelly EM and Shelly 3EM. The EM is for single phase and 3EM being for 3 phases.
They support both REST and MQTT with the stock firmware and doesn’t require internet.

Have a look here for EM

And here for 3EM

I have the 3EM but haven’t installed it yet.
There are some plugins/integrations to automatically add Shellys to HA which make it really easy to install.

I just installed it, but unfortunately it’s not yet supported in shellyforhass. Device itself works like a charm!

Shelly EM looks like exactly what I need, but @slovenc are you saying it doesn’t work with HA yet?
I need the 1 phase one but not sure if to get 50 amps or 120 amps as I see a breaker switch for 60 amps in my electric box…

EM works, 3EM doesnt work yet.

#9

Where is the integration? Is it custom?
Could not find it on https://www.home-assistant.io/integrations/#energy and I do see it advertised on the EM page too

I have this thanks to @luis_teixeira

how does this work? do you hook it up to the circuit in the main fuse box?

#12

correct, in my case I have it in a separate box for the pool

#13

cheers, you don’t have any photos of it installed do you please?

#14

Do you need to flash the tasmota FW on it or it works just fine out of the box since it does have tuya/smart life support.
I want something plug-and-play

#15

Also, you can actually use it to make your wife smart :rofl:

It’s a win-win really haha

#16

Right now I don’t have any, I’m sorry

#17

you can integrate it with the tuya but if you want to have the consumption values ​​in ha you need tasmota fw
by having tasmota you also turn the pairing button into a button to activate / deactivate the relay

#18

no problem, thanks… Just not sure if this would work with my current fuse box and if it did it would be a bit of a botch job… I want to monitor the lighting circuit and the studio in the garage (has a seperate fuse box)

Actually, I think you wouldn’t have a problem, it’s how I’m using it for the pool

#21

Just to confirm this can be used to simply show the power consumption and not used to actually turn on/off a circuit right?
Is it easy to flash the tasmota fw?

#24

With the original firmware u can see the power consumption only in the smart life/tuya app,switch too, u can use the switch in home assistant with tuya integration but not power consumption, if you flash tasmota u can use switch and have power consumption in home assistant, I flashed it one year ago with tuya-convert so easy
Sorry for my english :sweat_smile:
