Yes, but we should note that there are people who won’t use smarttiles for exactly that reason.
There were already two existing rules engines at the time that Bruce wrote rule machine. Smartrules is an iOS only app that you get through the App Store. (I believe they are working on an android version, however. )
The second was @joec 's “simple rule builder.” Also popular, but again there were people who didn’t want to use it because it went through a third-party host.
One of the requirements that Bruce had for rule machine when he started it, and one of the reasons that it quickly became so popular, was that it ran only within SmartThings. No external hardware or web services required. That had its limitations, but it also had a great deal to do with its acceptance.
So I think there’s a big difference between replacing rule machine and writing yet another third-party rules engine.
I think it’s always great to see more third-party options, and obviously smart tiles is an excellent example, but a new rules engine is not really a replacement for rule machine if it goes outside the SmartThings platform. That was really where @bravenel was so brilliant. Everybody else said, well, we’re going to have to use outside platforms, and he said, no, I can do it all in SmartThings. And he did.
