updating ol firmware

Hi

i am still with firmware 7.12 and i would like to update to 7.18. Should i do it straight to 7.18 or is it better to do it one at the time?

Thanks

you can update straight to 7.18 but you should backup your settings before the update.
You can do this in GHL Control Center via Backup and restore tab on top. Backup both, settings and sensor data.
