‘Thing’ is referring to the idea that many devices or ‘things’ within your home automation platform might also be useable as a way to play notifications. For example, you could play a spoken message over a Sonos speaker or Amazon Echo device.
They’re both great push notification systems. Here’s a couple of comparison points that come to mind.
Pushbullet offers 500 messages per month for free
Upgrading to Pro unlocks unlimited messages along with a few extra features
Pushover is a one-time fee of $5 per platform (eg. once for Android, once for iOS, once for web)
There’s a 10,000 message monthly limit per ‘app’, but most people are unlikely to hit it
Pushbulletonly works with Android + Chrome
Pushover works with Android + iOS + Chrome
Pushover has some neat additional options like Sounds and Priority that can be useful
eg. messages that continually repeat until you acknowledge them
Pushbullet has some neat features like notification mirroring (from your phone to PC)
I started using Pushbullet years back for other things, so I’ve continued to use it. I tend to use it for a variety of things - NodeRED notifications, pushing webpages from my phone to my PC for easier reading, etc.
I think@James uses both as I have him setup on some of my NodeRED flows with Pushbullet and I’ve heard him praise some of the neat delivery features of Pushover like the sounds and priority settings.
@Terri, I migrated all my Smart Home notification to Pushover about a year ago because I really liked the way I can choose different notification sounds and know if the notification is an informational or security related without having to look at the phone. The other great thing about Pushover is it will continue remind you until you acknowledge it if the notification priority is set to highest. Ex: I use highest priority notification when my garage door is left open for 30 minutes to make sure I couldn’t miss it.
It’s not a special option in the ‘Notification’ section… I just meant that if you have those type of devices authorized in your smart home platform (eg. SmartThings or Hubitat) then you can use normal Device Actions within your rules to send commands to those devices/things.
BTW, if you want to announce something on Echo devices, you can install Voice Monkey skill in the Alexa app, and use HTTP Action in Rule Engine to send the announcement text to the desired echo device.
See the Quick Start Guide for how to configure Voice Monkey.
