Jean Posted May 8 Share Posted May 8 My ISY994i is currently at Version 4.6.2. I would like to update to Version 4.9. Can this update be done in one step or are there incremental steps I should take? thanks! Quote Link to comment
jason.russo.96 Posted May 8 Share Posted May 8 Yes, but V5 unlocks a lot of features Quote Link to comment
apostolakisl Posted May 8 Share Posted May 8 5.0.16C is the final release for 994i that supports zwave 300. Upgrading from 4 to 5 may cause some quirks that you need to manually correct. Go through all of your devices and make sure they all communicate and look through your programs. When I updated, I recall very little in the way of issues. As far as I know, it is totally stable, free of bugs, and supports polyglot. If you don't have z-wave 300, you can update to 5.3.4. I have a 994i running 5.0.16c with polyglot running on an rpi and it keeps working without any surprises. v5 has a lot more features and aside from not supporting the latest version of polyglot, it has all the functionality of the most recent EISY. Make a backup, then download the update from the below link and follow instructions. Quote Link to comment
