I’ve been battling for hours to try and get Arlec GridConnect PC399HYA and PC191HA Smart Plug-in socket with energy meter recognised by TuyaLocal today.
The plug’s switch module was discovered easily, but I could not work out the right settings to get the energy/power monitors to work. I was going down custom-code rabbit-holes that didn’t need to be touched.
In the end, it was very, very simple - Everything was configured via the GUI with no custom YAML needed.
Summary:
Configure the existing switch entity to add the following IDs:
ID 1: Switch (already exists)
ID 18: Current (A) + Scaling factor 0.001 (Bug: must copy & paste this value into the UI)
ID 19: Power (W) + Scaling factor 0.1
ID 20: Voltage (V) + Scaling factor 0.1
Assumptions:
- LocalTuya is already installed.
- Your device has already been added to LocalTuya.
- You can see and control the ‘Switch’ entity of the device.
Refer here for LocalTuya installation instructions:
Lots more detail in this thread too:
Step-by-step guide:
In Home Assistant, navigate to Settings > Devices & Services.
Open LocalTuya.
Click “Configure”.
Select “Edit a device”
Select your Arlec Grid Connect Plug from the list
Tick “Add more entities in ‘edit device’ mode”
Change the Entity Type Platform to “Sensor”
Configure Entity as follows:
ID 18: Current (A)
Scaling factor 0.001 (Bug: must copy & paste this value into the UI)
Change the Entity Type Platform to “Sensor”
Untick “Do not add any more entities”
Repeat the Configure Entity process 2x more times.
ID 19: Power (W) + Scaling factor 0.1
ID 20: Voltage (V) + Scaling factor 0.1
After the 3rd (Voltage) entity is added, leave the “Do not add any more entities” ticked
Success!
Visit your “Devices” tab, and find the plug device
The device should now show the sensor values
Which you can click on and see the graphs
Click the cog to find additional configuration.
e.g. If needed, you can increase the display resolution if you have low-current devices like LED fairy lights.
That’s it!
Hope this helps.
