I asked earlier but it got buried in in the thread. But what are the units of measure in the CPU and memory graphs? When have you reached the upper limit of what the raspberry can handle? Here is my current graph shown from November 28th. When should utilization become a concern? Its hard to see an average because I mess with it a lot experimenting with settings but I currently have Power, ATO, Temp, 2 dosers on the built in PWM, and 2 light channels with the driver set to PCA 9685 but the hardware is not present. Check intervals are set to 10 seconds, light output was set to diurnal but I changed it to auto this morning. What concerns me is that memory creeps up as time goes buy. I need to set it and leave it for a week without touching it and see if it eventually levels out.
