The “original” Alexa Skill is the one named “Roomie Remote”, and it is working fine, can be added for new users right now, and AFAIK will continue working fine for the foreseeable future. At the moment, it even works with Roomie 10 in development (in other words, we didn’t remove it). There are 4 people left using that skill at least as measured over the last week. The reason for that in my view as I’ve said for years is that Amazon completely nuked the user experience about 5 years ago for every Skill. Skills (and arguably Alexa) cratered in the years that followed. Now I barely know anyone that uses Alexa. For a while there, it was like having a microwave, a standard home feature. Because of various changes they made, Amazon Skills became near unusable (eg. reading out the entire company name of the vendor for every single skill interaction). So at that point you either migrated to some other voice solution, dropped voice, or you switched to the Smart Home Skill.
Around 2017, Amazon introduced a Smart Home Skill system, and we had briefly renamed ourselves to Simple Control, so we called that skill Simple Control. It is still named that. The Smart Home Skill API was very slimmed down, just intended really to turn on/off lights and shades and such. Not designed to control an AV system. We shoe-horned into that for simple use cases. Just recently, they removed all such skills for new users, and will remove them for even current users in November as you note. (and as covered in at least one other thread here recently)
Yes, they do have a new, totally different system now. We could indeed develop a totally new integration for that. There are some unknowns as to whether it is really just software development or may involve additional certification as the original process did indeed involve many months (I remember it as six extra months, but my memory may be foggy on that) of extra certification with a high cost. Perhaps the certification will just carry forward. One can hope.
Today, 23 people use that skill (this week). While I am often a sucker for little features with only a few users, we implement things often that I know this specific device or use case only has a very small user base, etc. But I can compare 23 versus every other device we support as an example. There are a bunch of random devices with fewer users than that, but safe to say 23 is in the bottom 5% of devices used.
So at the moment we’re continuing work on V10. That will continue uninterrupted until it is finished which is sometime this Fall. Roomie 10 does include the new iOS 26 Speech Analyzer support which is basically a quality upgrade with far-field voice support for the Roomie Voice Control we have. It is definitely an upgrade. If you can put an iPhone/iPad in your voice zones, it’s clearly superior, faster, etc than Alexa. It’s now 100% local and you don’t have to be right next to it.
Alexa’s advantage is cost because you can place it in more zones for lower cost. Which is a bit odd because Roomie is most often used to control an AV system where you would indeed normally have an iPad/iPhone, and the Smart Home Skill can’t realistically be used for control. That skill is used to turn system on, turn system off. It’s a very limited API (the new one has similar limitations). So let’s not imagine that it was ever great. It was not great and then they killed it. It’s not great even if we update to it. It essentially has 2 commands (see photo below). It does fill some needs for a small group. What would be truly great is extending Roomie Voice Control to HomePod. Unfortunately, Apple has not yet opened that up. That could change.
Anyway, to sum up, the business level motivation to update to a totally new system for Alexa (we do have a working Alexa Skill as noted) is pretty limited. The new system doesn’t improve the user experience, it’s simply Amazon changing everything. So it’s really just nostalgia to make it work just because for a small number of users. When roughly November rolls around, we should have time to analyze this in more detail. It’s possible that will result in an updated Smart Home Skill. I’m certainly not opposed to that. We support all kinds of things I don’t use. But it is unreasonable to treat this as a priority as in the big picture, Alexa isn’t that and hasn’t been part of the equation for most vendors for many years.
