What Hub model do you have? What do you mean by partially connected and failed to join properly?
Without knowing more, I can only address the Aeotec Recessed Door Sensor 7, because I have that device and had issues with it on my C-5 (now retired) and C-7.
First, both on the C-5 and C-7, the Hubitat hubs seem to have smaller antennas than other hubs. The fix for that, if you will read these forums, is to install a Z-Wave repeater near your hub and to put repeaters around your home. Like many parts of life, I practice the Serenity Prayer and choose a path that fixes the issues I cannot change.
I suggest the Ring Alarm Range Extender 2, for several reasons (I’ve got 4). First, they are rather inexpensive ($24.99 on Amazon), and they have internal battery backup so your mesh stays up during power fail. Second, they seem to work well. Third, you can trigger a rule on power source switch from mains to battery which is useful if you have garage freezers powered on a GFCI circuit, as I do. That circuit also powers outlets on our patio that occasionally trip the GFCI, leaving our freezers unpowered. The Rule I set up sends me and my wife a notification so we can reset the GFCI. On the negative side, I have found them difficult to pair, and they apparently only report power fail events if paired securely, as reported by Bryan Copeland in these forums. Go figure.
Now, as to the Aeotec Recessed Door Sensor 7 (I’ve got 3). A bit of history. When they were first released, Hubitat came out with a driver (Aeotec Recessed Door Sensor 7) that worked well, at least for me. Aeotec also had a Door/Window Sensor 7. I have one of these on our garage door so that the Hubitat MyQ Lite driver can sense when the garage door is closed. When the Aeotec Door/Window Sensor 7 came out, Hubitat came out with a driver (Aeotec Door/Window Sensor 7) that worked well, at least for me. Then, to reduce code maintenance, Hubitat combined the two drivers into one (Aeotec Door/Window Sensor 7 Series) that is, in my opinion, very buggy. Search the forums, you will see some of the issues.
Once the Consolidated driver was released, the older, working, drivers became “Deprecated” and could no longer be selected as a driver for newly purchased Aeotec devices (like yours and mine). Hubitat has confirmed that there is no way for users to avail themselves of these Deprecated drivers. I have, multiple times, in my bug reports, requested a “Deprecated” section of drivers that could be chosen for regression testing and for a fall-back position when new, superseding, drivers are released. My suggestion has not, to date, been adopted. Perhaps if others turned in similar requests with their support tickets, this might receive priority attention. Seems reasonable to me.
I have turned in MANY bug reports (support tickets) on this driver. After many months of support tickets, I recently received a reply that the issues would be resolved in the next Hubitat release (2.2.4, the Holy Grail that we all await) that, as far as I know, has not yet moved into beta testing (search these forums).
So here is where we are: I have been able to get my Aeotec Recessed Door Sensor 7 devices and my Aeotec Door/Window Sensor 7 device functional, not bug free. Some of the devices, same device, same driver, report differently. One of the Recessed Door Sensors thinks it has a tamper switch (no, the device does not). Some of the devices report a serial number with a string of zeroes as long as your arm.
Bot here is what I had to do to get there: First, I have NEVER been able reliably to join the Aeotec devices to my C-7 unless paired next to the hub. I believe this is because Z-Wave 700 chips enter a low power mode during pairing to lessen the possibility of snooping. Second, although the documentation doesn’t clearly say so, the ONLY way you (or at least I) seem to be able to set parameters on the Aeotec devices is to wake them up (quickly hit the wake-up button or tamper switch, as appropriate) and IMMEDIATELY hit the Save Preferences button in the driver. Otherwise, the device never updates its parameters.
We wait for the next firmware release. Candidly, the C-7 introduction has been very rough, but things are much better. I hope you’re experience improves. Post in these forums with issues - it’s a good community, very helpful. An turn in support tickets for your issues. These forums are not official Hubitat support. If a ticket doesn’t get turned in, bugs don’t get addressed.
