I have installed OpenHab 2 on a Raspi Generation 1 (Model B). I am also using influxd as persistence servers to persist temperature items in a db.
It is generally working but sometimes reactions are really slow. Setting an item to “in house” after a motion sensor was triggered takes about 50s. I see that especially the Java task for OpenHAB and even more influxd are consuming most CPU time.
Is it possible that this is happening because the Generation 1 raspi is just too slow? How can I check if the CPU is the reason and re-installing on a Raspi 3 would help? Can I actually move the SD to another Raspi generation or do I need to reinstall from scratch?
Thanks a lot!
