Troubleshooting the Zmodo Greet Pro Smart Doorbell

Earlier this year I bought a Zmodo Greet Pro Smart Doorbell. It was cheap, didn’t require a monthly subscription, and had relatively decent reviews. It was a breeze to install, and had it up and running the day it arrived. Fast forward about 1.5 months, and something weird happened.

I was on vacation, enjoying Yellowstone in the Spring, and noticed while I was out that my home network wasn’t working. I couldn’t connect to Plex, couldn’t connect to my OpenVPN server, etc. My roommate notified me soon after and had to reboot the router to get everything working again. An annoying issue, but a simple fix.

Upon returning back home, I noticed everything working as expected, except my Doorbell was flashing a green ring. I looked this up and the Zmodo documentation says that indicates it’s ready to be setup. So I checked the Zmodo app and sure enough, it showed my doorbell, which was previously configured and working fine, as “Device Disconnected.”

So I removed the device from the app, and attempted to set it up again from scratch. However this is where the frustration set in. Every attempt to add it back via QR code timed out and didn’t work. I thought cutting power to the entry way could help reset the thing, but that didn’t do anything. And to my surprise, it was still powered on when I killed the power. I just learned this thing has a battery.

Next I remove the thing off the wall, remove the back panel in an attempt to find the battery and disconnect it. Turns out I couldn’t locate that, so I just left it and waited for it to die on it’s own. It took about 15 or 20 minutes, but it eventually died out. So I put everything back together, plugged it back in on the wall and it now showed a solid blue ring. Documentation says this indicates it’s connected to WiFi. Sure enough, I see the device on my router. So I tried adding by QR code again to my app, and it still didn’t work!

This is when I found this Zmodo support article that mentioned how to add the device back to your app if it’s already connected to WiFi. You must add it by using the “Wireless Device and Smart Kit” option instead of the QR code option. Choosing “Wireless Device” from here, the app was able to locate the doorbell on my network and get it back into the app. Voila! I can now spy on the unsuspecting outside world.. that is on my front porch.

To summarize:
- Wifi going wonky can cause Zmodo Greet Pro to lose its mind, and flash a green ring
- When that happens, remove the doorbell and let its battery die all the way down (it will stop flashing green)
- After the battery dies, reinstall it and connect it to power. I’m guessing this would be all you need to do to get it working again. In my case, I had removed the device from the app before killing the battery
- If you removed it from the app like me, re-add it once the ring is a solid blue, by using the Wireless Device and Smart Kit option

vROPs for Horizon - Regain Compatibility and Insight into your VDI

If your business happens to utilize VMware Horizon for VDI, and vRealize Operations (vROPs) for infrastructure monitoring, insight, and capacity planning, you may also be a business that uses the vROPs for Horizon Adapter (V4H) to bring that level of insight into your virtual desktop infrastructure. That being the case, you likely noticed that good stretch of time where vROPs 6.7 broke compatibility with the existing vROPs Horizon Adapter (V4H) 6.5.1 forcing you to delay upgrades, or lose your vROPs insights into the Horizon environment until it was fixed.

So what's needed to bring everything to compliance and compatibility to get insight back into Horizon with vROPs? Ultimately, you need the 6.6 adapter and a patched vROPs instance. The V4H Adapter 6.6 now supports vROPs 6.7 and 7.0. And the process for patching and licensing the vROPs instance is outlined below.

Step 1:  Upgrade your V4H license

Head to the VMware Portal and find your vRealize Operations 6 Manager for Horizon license. Go through the process via the portal to upgrade it to vRealize Operations Manager for Horizon

Reference: How to upgrade license keys in My VMware

Step 2:  Patch vROPs

Follow the steps outlined in KB 60301 to apply the appropriate patch to your vROPs instance






NOTE: vRealize Operations Manager 6.6.1 GA, 6.7 GA, and 7.0 GA, do not include the Security Patch.

How can you tell if you already have this patch? 
If you're on version 7.0 and you see the patch below, you're still on GA and need to apply the security fix. Once it's been applied, you should see  build 7.0.0.11287812. Verify your working build per the KB linked above.







Step 3:  Install the new license 

Implementing the new key in your vROPs manager will bring compliance and compatibility once again. Here's the official documentation for applying licenses.

For the latest on vROPs and Horizon compatibility, always check the Interop Guide, and take a peek at KB 59651 as well.

Happy patching!

VMware Recertification Rollback


Whoever thought we'd see this?! VMware made an overwhelmingly well-received change today regarding its VCP Certification program. Effective immediately, VMware is removing the requirement to recertify their VCP certifications within a two-year period. The decision to update and recertify is left up to YOU!

What does this mean for your expired certifications?
If you hold any of these previously expired certs, it will flip to showing Active starting in April 2019. If your cert changes to being active, you can complete the upgrade path to earn the latest version - no more expired cert upgrade path!


What if you spent time and money re-certifying one of these newly active certs?
VMware will provide you a free one-year premium license to the VMware Learning Zone - assuming you certified within the last 6 months.

Check out the official Blog Announcement and happy certifying!
