+[The garage door monitor that I built earlier in the
+year](@posts/2022/garage-door-monitor/index.md) has by all accounts been
+running perfectly since I installed it. Recently I implemented a couple of new
+features that I've wished for over the last few months.
+
+<!-- more -->
+
+The first new feature is a bit more visibility into the state of the system. I
+added uptime and memory info to the web page:
+
+{{ figure(image="posts/2022/garage-door-monitor-update/webpage.png", link="posts/2022/garage-door-monitor-update/webpage.png", alt="Screenshot of the web page served by the garage door monitor. It shows the state of the door, uptime of the device, and memory usage information.", caption="Screenshot of the web page now including uptime and memory info.", width=625) }}
+
+The second and more practical addition is a subsequent notification when the
+door is closed again after it was left open for longer that the trigger time (5
+minutes).
+
+{{ figure(image="posts/2022/garage-door-monitor-update/new-mattermost-notification.png", link="posts/2022/garage-door-monitor-update/new-mattermost-notification.png", alt="Screenshot of the message posted to Mattermost by the garage door monitor. It reads: Garage door closed after 5 minutes open.", caption="The new notification", width=403, border=true) }}
+
+Since I set up the garage door monitor I haven't accidentally left it open.
+However, I have triggered the notification when washing the car or packing for
+a road trip. It's this latter scenario that I wanted to address. The issue is
+that because the notification is triggered during packing if I did set off and
+forget to close the door I wouldn't know. One way to deal with this would be
+recurring notifications. I chose another option though.
+
+When the door is closed after notifying that it was left open, it sends another
+message saying that it's now closed. The benefit of this approach is that the
+message log now properly tracks the state of the door, so if I'm a few kms down
+the road and wonder if I closed the door it's just a matter of checking the
+channel in Mattermost.
+
+Before I powered it off to update the Buildroot image on the SD card I hooked
+up a serial console and checked its uptime. I was pleased to see 100% uptime
+since it was first installed:
+
+```
+ 02:03:14 up 183 days, 20:26,  load average: 0.00, 0.00, 0.00
+```
+
+That's all for now, on to the next few hundred days of service!
