To update to version 3 of Node-RED for groov Box, you need to have minimum groov Admin 1.570.44. But the current version of groov Admin is 45, and it includes a security fix. So if I were you, I'd make sure my Box has Admin 45.
If you have groov Admin 45, you already have the version 2 upgrade of Node-RED. Here's why: We first added Node-RED to AR1s in groov Admin 44. When we released the Node-RED upgrade v2, it was delivered as part of groov Admin 45.
But with v3, we are now starting to deliver Node-RED upgrades separate from groov Admin. That's why the file size on v3 is much smaller than the file size on v2.
- If you have groov Admin 45, just upgrade to Node-RED v3.
- If you have a lower version of groov Admin, upgrade to groov Admin 45 and then Node-RED v3.
And good point about factory defaults. That really does mean putting the Box back to where it was when you first got it, so you do have to install upgrades since then. Thanks for mentioning that.
