Plugin fails to load after reboot

[dnasini]

After installation, Octoprint pops up a message saying "Install Unknown" and the green flag that says "everything is correct" and asks for reboot. After reboot, the PSU Control - Meross plugin is not listed into the installed plugins. Having a look to the logs, Octoprint reports those errors

Hello, It appears that something went wrong with the package installation. This probably has nothing to do with me.

Are you still able to replicate the issue? (Considering that the ticket had been opened a while ago)

Hi, well it could be. Anyway, at that time I tried more than once to reinstall the pluging with same result. After your reply, I noticed a new version is available. I just installed the last one and now sounds it works. No strange message at the end of the install phase and after reboot I see it listed in the plugins list. I'll test it later and, just in case, I'll let you know.

Please do tell if it doesn't work - I can give you pointers to how fix this error if you're comfortable with SSH'ing to the device.

Hi, it tooks a while to config and test it but it sounds to work fine.

Thank you
