Hi, I was browsing your code and found you want to get the status of the kettle heater element.

Assuming you do have a kettle_ID:

kettle = self.cbpi.kettle.find_by_id(kettle_ID)
heater = self.cbpi.actor.find_by_id(kettle.heater)
kettle_heater_state = heater.instance.state

Regards,
Alex

CBPi Version can be retrieved via this object which is independent of any path.

    async def show_standby(self):
        ip = await self.set_ip()
        cbpi_version = self.cbpi.version
        ............

I experienced this already with the cbpi3 version when I connected the pi to ethernet and disabled the wlan connection.

Although the get_ip function has a try, the issue appears because there is no except.
By adding the except, the issue is solved. WLAN returns with 'Not connected' and the scrit moves on the eth0

    async def get_ip(self, interface):
        ip_addr = 'Not connected'
        so = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
        try:
            ip_addr = socket.inet_ntoa(
                fcntl.ioctl(so.fileno(), 0x8915, struct.pack('256s', bytes(interface.encode())[:15]))[20:24])
        except:
            return ip_addr        
        finally:
            return ip_addr

Hi Followed the installation instructions on - https://craftbeerpi.gitbook.io/craftbeerpi4/development#4-install-your-plugin-locally

I cant seem to get it to load, see below!

2021-07-20:08:57:45,986 ERROR [plugin_controller.py:58] FAILED to load plugin LCDisplay
2021-07-20:08:57:45,986 ERROR [plugin_controller.py:59] No module named 'LCDisplay.RPLCD'

Thanks for your help.

smbus2 is required for the plugin which is not installed per default. This could be added to the setup.py and would be installed automatically with installation of the plugin.

packages=['LCDisplay'],
install_requires=[
'cbpi>=4.0.0.33',
'smbus2',

I've recently installed CBPI4 after using CBPI3 for about a year without any problems. The LCD worked fine with CBPI3.

The plugin loads fine, no errors and the i2c address is recognised but nothing appears on the display. When the CBPI server is stopped I get the following error:

2022-06-14:13:22:00,928 ERROR [base_events.py:1738] Task exception was never retrieved
future: <Task finished name='Task-5' coro=<LCDisplay.run() done, defined at /usr/local/lib/python3.9/dist-packages/cbpi4-LCDisplay/init.py:127> exception=TypeError("'NoneType' object is not subscriptable")>

sensor_type = (sensor_values["sensor_type"])
TypeError: 'NoneType' object is not subscriptable

I've done a number of clean installs of CBPI4 and re-installs of the plugin but the error persists. Any ideas?

Many thanks in advance.
