So my wife bought some smart plugs and I can not find anything about them for home assistant. they are Sylvania smart+ plugs.
These do not work with tuya, smartthings, or smart life.
This is what I have tried.
reset the device add to Sylvania app works fine but no way to add to HA
reset the device try and add to tuya fails to connect to wifi.
reset the device and try the Sylvania app again and it works fine again.
take a known tuya plug and reset it and add it to the tuya app no issues and can add it back to HA
at this point I can not get it to add to the tuya app, and I my tuya app is working
I did the same thing with smart life app
now I feel like i have went down the rabbit hole. After more googling and searching I found someone that tore the same plug apart and found the processor. It is an EWN-8250
searching the FCC ID I found that it is a Tuya device…
can anyone point me in the right direction to get them into HA?
They are Tuya and respond to the Tuya SmartLife app. There are multiple integrations to install Tuya, one is Core that uses the cloud, and several in GitHub available using the HACS loader integration that use the cloud initially then don’t later.
And Ya, if you got them from Menards for $3 each, so did I. Bought a dozen for my Christmas lights. Tuya WiFi is really crap AFAIC, but I figured I’d deal for the seasonal use.
I tried once to load one up but ran out of time. I’ll let you know if I figure anything out.
So smartlife sees them but times out on connecting, so I see what you mean. hmmm
The sylvania app loads them right up.
The actual app software appears identical.
Must be a tweaked code or something. Damn…
Well I managed to get them into Google Home. I may be able to do what I want there… These are seasonal for me, so…
Just no… That is less reliable than the rf433 switches I have now. Some get stuck, some take randomly 30 secons to change. Wow… Sylvania integration used thru google home BAD!
This has some info for bulbs same company.
There are current posts at the bottom. just not about the plug.
Cloudcutter can be used to flash these with ESPHome. I don’t see any energy monitoring but on/off works fine. If anyone knows how to get energy monitoring going, I’m all ears.
I picked up a 4 pack of the plugs at my local Menards for $7 on clearance. 4 pack of bulbs for $6.
I have used cloudcutter on 1 plug and 6 bulbs so far.
Rough guide for the plug:
Plug it in. Wait for it to fast flash
Hold power button for 10s to get it into slow blink mode.
Run cloudcutter
Flash 3rd party firmware
By Manufacturer/device name
Sylvania
75702 Smart Plug v1.0.7
Select the only firmware version there…
Select ESPHome-Kickstart v23blahblahblah
Let cloudcutter do it’s thing and follow instructions on the screen.
When you see the kickstart wifi network on your phone, give it your wifi credentials.
Now HA will see it…
Update the YAML with the config from here, changing things as necessary like OTA and API: UPK2ESPHome
I have a ugly contraption at my desk where I can flick a switch on/off to control an outlet where I have it plugged in which helps immensely.
Update: I spent all afternoon trying to get energy monitoring and had no luck.
I was able to get them to work with local tuya though.
Before you get to actually running the python script, modify pyscript_modules/tuya/const.py and comment out the top two lines. Uncomment the Sylvania lines. Also, change the TUYA_ENDPOINT url to be “https://a1.tuyaus.com/api.json”
Run the script and get the local key.
Add to localtuya (installed via hacs). When adding the integration, you don’t need to setup a cloud api key so check that box… Then add the device using your local key.
I tried here to get energy monitoring working as well by exposing dps 18,19,20 manually but the values always read -1 so I do believe this device has no way of actually exposing the energy monitoring.
