I have always stayed away from ato' s specially after seeing fellow reefers go through issues but I will be taking a longer vacation later this year and would like to have as fool proof a setup as possible. So I need help putting something together. I want something controlled by my apex, switches running through a breakout box. I like the avast setup but want to have more redundancy. So I guess what am asking is how to add more sensors to make it as safe as possible, also if using float switches I would like to get good quality. Budget is probably $250-400 for entire setup but I will spend more if I need to. Thanks for any help in advance
