unificontrol and PyScript

[nickolas1969]

My first attempt with PyScript is to use the unificontrol module to make a script that logs into my home unifi controller and blocks/unblocks a MAC address passed to the script.

I added “unificontrol” to requirements.txt as stated in the docs for adding external modules.

in my script I followed the “hello world” service example: adding my import at the top of my unifi.py script, and altering the parameters to keep “action” and look for “block” or “unblock”, and the “id” changed to “mac” and would be the MAC address to act on.

the script works in my external Ubuntu server, so code is good. Does it sound like I did the external library import correctly?

To better analyze the cause please provide logs of the executed pyscript script, the script body, the requirements.txt body, and the pyscript directory tree screenshot. If you don't know how to provide any of these - please let me know, and I'll describe them in detail.

This error originated from a custom integration.

Ahhh!! Ok, so be making a call to a rest API of another system, PyScript wants that done a different way. I need to find docs on how they want "await hass.async_add_executor_job()`"?

Here is the full script I am using.

import unificontrol

@service
def block_mac(action=None, mac=None):
    client = unificontrol.UnifiClient(host="10.0.0.5",username='<snip>', password='<snip>')
    log.info(f"block_mac: got action {action} mac {mac}")
    if action == "block" and mac is not None:
        client.block_client(mac)
    elif action == "unblock" and mac is not None:
        client.unblock_client(mac)
    client.logout()

[nickolas1969]

I did try wrapping the client.block_client() in the await hass.async_add_executor_job() in place, but that threw an error saying the call needed to be somewhere else.

Maybe PyScript in HA isn't what I need to allow HA to reach outside it's world to change other API's, due to the async nature of how it's running.

You need this documentation block: https://hacs-pyscript.readthedocs.io/en/stable/reference.html#avoiding-event-loop-i-o

@nickolas1969 Why don't you just use the unifi integration? It provides a switch entity for each and every wifi device. Using these you can just use the switch.turn_off service to block a client in your wifi.
