I have four iBlinds all connected to Hubitat and I have a virtual switch that is used to open or close them all. The issue is when the virtual switch commands all the blinds to close. The first one closes, the second one does not, then the 3rd and 4th closes. My rule even circles back to make sure they are all closed and, if not, sends a close command again to the open one (including screenshot of my rule). I have checked the open blind's status and it shows as closed in Hubitat. But it's definitely open. I should also mention that maybe once out of every 50 times they all do close.
What hardware revision of iBlinds are you using, and if v3 or v3.1, what firmware? (These are the latest and the only ones with firmware updates available). Also, what driver are you using for these, built-in or custom?
This is a common complaint with these, perhaps because they are often located inside metal headrails and not the best environment for radio communications. Commanding large numbers of Z-Wave devices at the same time is also often a recipe for disaster. It looks like you're only doing two commands at most, but inserting a second or two delay between may still help.
The other thing you can do is rule out a problem with the rule by enabling all logging and seeing if anything unexpected comes up, or check Logs already for errors or other problems that may be apparent from this rule or the devices.
Make sure your iBlinds are on the newest firmware. Then the C8 made a big difference in my iBlinds response. Might also add a little delay between each blind.
I'm using V3, firmware version 3.12, hardware version 2
I had a delay in it before and it didn't help. But I decided to try again. Put a 3 second delay after opening Blinds #1. And it worked. Here's hoping it's good for now on!
Hoping it doesn't come to this... I've never been good at figuring things out from looking at logs.
I'm using firmware version 3.12 currently. Not sure how to make sure it's the latest update and, if not, how to update other than doing a full Hubitat update.
That looks like that is the lastest. https://support.myiblinds.com/knowledge-base/iblinds-v3-firmware/
I would try putting in a 5-10 second delay between each blind command to open or close.
So, open blind 1
Wait 5 seconds
Open blind 2
Wait 5 seconds
Open blind 3
I had v1 and tossed them, way too glitchy.
I now have 5 * V3 3.12 hw2 blinds and they seem to work fine with a 1 seconds delay. I am using WebCore and they are in a device group; the max allowed is 1000 ms.
I did query support a year ago and they suggested a longer delay on each command. I think they were more worried about congestion on the Z-Wave network but I think not. When I boot my C8 I run 2 pistons to refresh my ZB and ZW network with 1000 ms spacing; it never seems to flood the radios.
