For some applications (like when you want to connect the BIGTREETECH E3EZ* ) you might want to increase the timeout for the shutdown of the BIGTREETECH Relay 1.2* . Especially in the case of the E3EZ the issue is that the power of the PSU is also the power for the Onboard CPU (e.g. CB1* or CM4). So when this power cuts too fast, the PSU would be switched off before the CPU has shutdown. Lastly you might want to be able to start the relay through the pins (and not just shut it down) instead of resetting the device. ...

Recently i wanted to flash another Wemos D1 Mini but actually had no chance to do it from my Windows 10 PC. Symptom: 1 failed to execute 'open' on 'serialport': failed to open serial port.

Recently i managed to change a file in the Home Assistant configuration and then i forgot about that change… a bit later i started the upgrade to the latest version of Home Assistant which doesn’t check if Home Assitant could be started with the current configuration … of course i had managed to break it and so home assistant “core” didn’t start. The solution was to logon either via SSH (if you have the addon installed and configured) or to have access to the console of the Home Assistant OS. Once you are logged on, follow these steps: ...

Today i wanted to use the command unzip on my Synology NAS but it couldn’t be found. The solution was easy: Synology only delivers 7zip instead - which is indeed good since it is a bit more universal. So to unpack a zip-file, the command is: 1 7z x filename.zip

On my BIGTREETECH E3EZ i switched from the CB1 to the Raspberry PI CM4. Unfortunately on every boot the following message appeared: 1 brcm-pcie fd500000.pcie: link down The issue is the missing PCIe Port, hence you have to disable the feature to get rid of this message. Create the file disable-pcie-overlay.dts with the following command: 1 wget https://gist.githubusercontent.com/SirUli/de94ddb751b91adfa6809f286a18a382/raw/af010907360153f74edc8f65d415d717378bf037/gistfile1.txt -O /tmp/disable-pcie-overlay.dts You must then convert the file using the following command: ...

Solution There are different solutions for this but the following one worked the best for me: First remove NTP: 1 sudo apt remove ntp and install the systemd-native timesync service: 1 sudo apt install systemd-timesyncd This should automatically install the service and start it. To make sure, you can check that systemd-timesyncd.service is active (running): ...
