Interacting - flick a lever.

[j-romchain]

I want to have it start a farm, to do so it just needs to flick the lever. Are there commands to 1. Find the lever, and 2.flick the lever?

You would need to write a C# script, but I'm not sure if there is a way to retrieve the state of the lever currently.
Example of script: sample-script-with-world-access.cs (lamp state can be retrieved in 1.12 and lower at the moment) OK I misread your question, you want to flip the lever, not watch for it and run an action in MCC, see answer below.

You might be able to do so using the /useblock command, however I'm not sure you can look for a certain block type at the moment, you would need to open the game first and take not of the exact coordinates.

Block states are not collected past 1.13 due to the way terrain is sent now.
For a "block search" feature, feel free to open a feature request by creating an Issue 🙂

So lamp watcher no longer works?

Unfortunately, yes

Can you fix it?

Not easily as Minecraft now has more than 17000 different block states. Related: #599
