I’d suggest you create a new separate piece of equipment for, say, ‘General brewery’. It will add extra complication to try and tie this to your brewing system, so I think keep it as its own piece of equipment. You can do this from Production → View → Equipment. Then, in the cleaning and maintenance section, you can set up processes to check your baiting stations or clean the walls. These tasks can then be triggered manually from the piece of equipment’s page, or you can set schedules for the tasks, so you’re automatically reminded.
Would this work for you? Let me know so I can either close this request or we can discuss this further.
