SolPipLog v2.3.0 (Gandalf) Hangs #25

Closed Schmidt-Heinrich closed 4 years ago

Schmidt-Heinrich commented 4 years ago

This is an intermittent problem that I am struggling to find the source of.

Using a Pi4-4GB model.

I wrote a "emonpi 17Oct19" image as a base. Loaded all the required GUI elements for Raspbian Next I loaded SolPipLog v2.3.0

My suspicion is that I have a buffer issue of some kind, but I am grasping here.

Any advice or solution I will be grateful for.

GREAT product!

I had a similar problem during my installation. I had a 3 amp power supply that was barely producing 1.5 amps. It worked reliably until I plugged it into the inverter. My thinking is the logic in the PIP uses the power from the USB on the raspberry to function. It always worked fine until I plugged it in, and then it would hang at very random times.

Thank you for sharing you experience. I have tried two different Raspberry supplied power supplies, same result.

I have scheduled a reboot at midnight for now. Of course this is not a solution but will remove the impact at this stage.

I presume you are not using emoncms. what errors are you having ? I could make a image available with all configured. How do you start solpiplog ? execute "top" or "htop" from commandline and you will see processes that are running and with high CPU usage. I have a PI4 and i am using the official power adapter from them. But i have to say that i am using solpiplog at this moment on a Raspberry 3b+ The PI4 is for programing. p.s. v 2.3.1 is available
