I got an email from Hayward to update the firmware for my Omni Controller. The current version is R4.0 and my version is R2.2, so I'm guessing a little old. However, everything is working fine and while I feel completely competent to follow the steps, I'm not so confident that I could recover my current state if something goes wrong. Is there really any benefit of updating firmware if everything is working? The one benefit as described in the email is that after this update, all other updates can be done directly. I assume that means that they'll just push the update over the internet, similar to what happens with my computer, printer . . . I'm not sure that's a good or bad thing as I generally set up my computer equipment to warn me of updates, not just install them automatically. Wondering whether to leave good enough alone or try to play pool controller technician.
