I would like to report success using 6 of these motors with HomeSeer HS3 (now on HS4 Beta running on Debian 10 Linux).

I was originally using the Pi version of HomeSeer with a Z-Wave.Me RaZberry2 (Z-Wave Plug-On Module) but upgraded to the Linux version of HS3 as I needed more than 5 plug-ins. I continued using the RazBerry for Z-Wave access (via a network link) and I never had any issues joining iBlinds or any other device to the network in a 3-storey townhouse with HS3 centrally located on 2nd level (max distance for every Z-Wave inclusion I've tried would be about 25 feet). I've just replaced the Z-Wave.Me with the Nortek HUSBZB-1 Z-Wave + ZigBee USB stick on the Debian 10 box and it's working fine. I did observe one blind started to re-calibrate every time I sent a command to it but discovered the battery was down to 38%. After recharging it, it returned to normal. I use an outdoor luminance meter to detect the amount of outdoor light at which I want to open/close the blinds rather than sunrise/sunset as some days are darker than others.

I created open/close events in HomeSeer to open/close the 3 kitchen blinds via the iBlind on/off child, two living room blinds also via on/off and one master bedroom blind that uses the multilevel to open 25% and I use Alexa voice routines (yes, I have Alexa working with HomeSeer!) to trigger these "scenes" that she successfully discovered from HomeSeer: "Open kitchen blinds", "Close living room blinds", "Open bedroom blind", etc. The bedroom blind does not open via the luminance schedule Monday to Friday and I tell Alexa when I wake up to open them on those days. HomeSeer does open them on weekends with the others since I am not home then and they close on schedule via HomeSeer with the others 7 days a week. The Alexa/HomeSeer skill is somewhat broken in that the multilevel device causes Alexa to sit and spin saying "Waiting for HomeSeer...".  After extensive tinkering, I found that adding a single additional "Dim" value of any number between 1 and 98 (I use 50) in the Status/Graphics pairs for the device then allows Alexa to connect with HomeSeer when I click on the dimmable device. The % slider then shows although Alexa does not know what level they are at. I can slide the slider to the desired % and she submits the command to HomeSeer, the blinds respond but then Alexa pops the slider back to zero saying there was a problem. This however is a general issue with the Alexa/HomeSeer skill with *ALL* multilevel dimmable devices, not just iBlinds.  HomeSeer support responded to this saying they do not support manual control via Alexa, only voice control which is a pity since I think they are close to having it work correctly.

I also created events in HomeSeer to "sync" the on/off and dimmer settings which are triggered by changes to the on/off switch &/or the dimmer switch and sync the other child status via its node number.  I.e. if the dimmer changes from 0 (closed down) or 99 (closed up) to an open position (1-98) I update the status of the on/off switch to "On" and vice versa.  Also if the on/off changes from open/closed, I update the dimmer to "50" (open 50%) or "0" (Closed down) which is the positions the on/off switch triggers the blind to adjust to.
IF
Upper Level Master Bedroom iBlind Master Bedroom Bedroom Blind Multilevel was set and has a value that is not equal to a value in the range of 1 to 98
THEN
Execute the command: &nhs.SetDeviceValueByRef(138, 0, False)

IF
Upper Level Master Bedroom iBlind Master Bedroom Bedroom Blind Multilevel changes and becomes a value in the range of 1 to 98
THEN
Execute the command: &nhs.SetDeviceValueByRef(138, 255, False)

IF
Upper Level Master Bedroom iBlind Master Bedroom Bedroom Blind had its value set to Close
THEN
Execute the command: &nhs.SetDeviceValueByRef(139, 0, False)

IF
Upper Level Master Bedroom iBlind Master Bedroom Bedroom Blind had its value set to Open
THEN
Execute the command: &nhs.SetDeviceValueByRef(139, 50, False)

P.S.
I also have 2 solar chargers that I planned to use on the two blinds with the most sun exposure after I spoke to tech support about whether they would work well here in Vancouver BC.  He advised they should but likely only on the southern exposed windows.  I did try one of them on my living room blind which faces north and it did not work (at first).  After pondering this, I cleaned the window AND removed the windows screen and now it is charging the battery by about 1-2% per day while opening/closing twice a day and polling every 23 hours.  The one I mounted to the southern most facing blind is also behind a dirty screened window but it is keeping the battery at 100%.  I will have to wait until the short dreary overcast days in December to see how they fare then.  So keep this in mind when mounting your solar chargers...
