Thx for the update. For me it's the other way around. I was messing around with some Sonoff switches, which are powered by esp866 and esp8285. I had some trouble with the stability of esp easy. I tried some "advanced" stuff like simple rules, etc. The modules were running at pretty high load and I had some performance issues. However my little weather station, which is basically a bme280 connected to a esp8266 running esp easy, that uses generic http as a controlle, is running fine.
For my boat I would still try to get a bulletproof system and use Arduino ide instead.
