hi, iam very new to hass,
i want to use my ELV switch but getting following error:
Integration pca not found when trying to verify its switch platform.
iam running 0.97.0b2
i added following in configuration.yaml:
switch:
platform: pca
device: /dev/ttyUSB1
i also install the perl module pypca
thx
tom
Do you get that error when running a release version (not the beta)?
Did you correctly format that switch: block in your configuration.yaml? Did you run a configuration check?
same error with release version. the config check outputs the error: Integration pca not found when trying to verify its switch platform.
the switch block is exactly as stated here:
switch:
- platform: pca
device: /dev/ttyUSB1
i have changed platform from pca to elv, and now at least i dont get integration not found.
i need to test this later
cant get it to work. if i scan manualy for my devices i can find them:

i turned on logging, and just found out that the switches are there, but did not get auto added:

and i found out i can see them in homekit in the home app but i cant switch them off, automaticaly switching back to on.
if i press the manuall off switch, the status of the switch is updating in homekit.
ah now i can see them in the gui. it just takes a while i think.
but i cant switch them off 
Anyone got an Idea?
Hi, I’ve got exactly the same issue.
It was quite easy to make the PCA 301 devices visible in HA using a JeeLink and this instructions: https://www.home-assistant.io/integrations/elv
Currently I is just shown in the UI and cannot be controlled in HA. How to control the devices really with HA?
Same issue here.
Switch are created, but i can not control them. No power or energy sensor were created.
Hello, I have the same problem. Has a solution been found here?
Since the HA integration did not work, but I still had a few of the PCA301 adapters in use via a workaround Fhem → IO-Broker → HA, I decided to write a new integration for it.
The integration works really well for me, adapters can be switched and the measured values are also delivered.
Here is the link to the Github repository:
Integration via HACS, see also the instructions in the repo.
It should also be available via the HACS library shortly.
No custom repository is required. The integration is available directly via HACS
