A few weeks ago (I wrote here) (https://homekit.blog.com/r/HomeKit/comments/bhvfky/hunter_douglas_powerview_homekit_delay_and_lag/) about issues I had with the PowerView HomeKit integration, such as Laggy response times and grouped blinds that didn't move at all.

I have also sent them about this as well, and originally got a standard rejection response from the customer service team. Today I received a mailing list from an engineer working on the PowerView HomeKit system, and here's what he said:

> Hi, I reviewed recent cases regarding HomeKit integration with PowerView and found the questions you sent to Hunter Douglas. I am a test engineer working on PowerView development, and I have been using HomeKit in my own home for PowerView and other HomeKit accessories for months. I think the answer you received was missing and that you deserve better answers to your questions.

> "Compared to using the PowerView app, HomeKit is quite slow to control the blinds. This doesn't happen with any other HomeKit product."

> Apple Home App calls scenes differently than PowerView. With our PowerView App, we call a scene number, and every shadow that is a member of that scene goes to the intended position, and it all starts quite a bit at once. The Apple Home protocol is calling each shade individually one at a time, resulting in each shadow starting one at a time. This is Apple's protocol. On the plus side, The Home app has some built in redundancy for scenes and automation that we don't have in the PowerView App.

> "When blinds are grouped in HomeKit, sometimes only one of the blinds will move."

> I have to say I don't see this. I have grouped many shades together in HomeKit, even different types of shades, and I have very good reliability with this. If you can tell me what type of shades you have and how many you are trying to group this problem with, I will try to replicate the problem here and seek a solution.

> I regret that the first response you received was so tame and vague. I have discussed this with our customer service group and hope that we can provide better answers to future issues.

If anyone else has these issues, I recommend sending an email to HunterDouglas Customer Support with your issue so we can resolve the issue. It's good to see that there are people at the company looking at this and trying to help.
