Hi there After trying a lot and deleting some old block and Lua scenes, I noticed that the RAM memory usage is getting higher and higher. I tried a lot, created a few block and LUA scenes and deleted them again. In my estimation, the memory requirement should have decreased because I only actually deleted it. I already had the problem that the HC3 became unstable at 96% memory usage. Do I have to expect the same problem again? Greetings Frank   e2a87a9e56d75bc0a6836d88b
