NodeJS version compatibility
Hi and thanks for the awesome plugin!
One question, if I may ask - 
Why do you keep updating the `engines.node` version in package.json to the latest *patch* version, all the time?
It requires the user to upgrade NodeJS for every new patch version, or otherwise click on "Update Anyway" when updating the plugin.
See [`homebridge-config-ui-x`'s package.json](https://github.com/oznu/homebridge-config-ui-x/blob/master/package.json) for example - they're compatible with `"node": ">=10.17.0"`... I'm pretty sure that this plugin will be compatible as well. 
What do you think? :)
Thanks again!
