Apologies for resurrecting an old thread but as it’s the only one that I can find that touches on integrating Anova cookers and largely ended up unresolved for more modern models, in case anyone’s still interested I’ve taken the time to put together a CLI wrapper similar to @danodemano’s that uses ammarzuberi’s pyanova-api and works with the Precision Cooker Pro (may work with other models but is untested).
There’s also an example of a command line sensor that works to pull all the info available to pyanova-api into HA in the readme.
I’ve put implementing commands to start/stop/edit cooks on my ‘to do’ list but am not sure I’ve actually got much use for this personally so can’t guarantee if/when I’ll get round to it, I just wanted something to report on a cook’s status in HA myself.
