I moved to trigboard Ver 7 to use PushSafer rather than the version 4 Pushbullet notifications. PushSafer is German internet based service to push notifications. I find it fast and reliable. From the mailbox to actual use with the preconfigured trigboard load took 15 minutes or less. As for user configuration the version 7 trigboard is much improved over version 4.
This was my first time to set up such a device. The videos and documentation was more for the person who knows the development environment for Arduino type devices. Since I don't know this environment, explaining the buzz words or replacing them with easier to understand language would help. As a retired electrical engineer, I could follow the author's design well for the circuits. What I am less experienced with is the software and APPs. BTW, the PushBullet APP is run by greedy developers.
