Shelly Sensors: Exposing my data addiction

If there’s one thing that I’ve learned from my use of Home Assistant it’s that data is addictive. In creating a strategy for whole home backup power, I selected the Shelly 3EM as a tool to track how much power the house draws. That provided a solid information to help in choosing a generator. It also started me down a path with inexpensive Shelly sensors.

When I later added a generator inlet to our garage, I opted for the newer Shelly Pro EM 50A. The new “Pro” models supports three kinds of connectivity; Wi-Fi, BT and Ethernet.

Dealing with Netatmo Sensor Issues: A Personal Experience

We’ve had a Netatmo Smart Weather Station since 2017. As I recall, it was gift. We have the basic system, with two additional room sensors. We added the rain gauge in 2019. It was readily integrated into Home Assistant. For an IoT device, it’s worked very well. That is, until very recently.

Back in June we had an incident involving the large Pecan tree in our back yard. After an extended rainy spell, it lost a major limb, which came down onto our deck and the roof of the house. The roof was damaged in two places. The deck was destroyed. The remainder of the Pecan had to be taken out completely.

Google TV Streamer: A Streaming Media Upgrade

Last month we observed the one-year anniversary of our forced migration away from our decades long love affair with Tivo DVRs. That transition, forced by Xfinity, also inspired our migration to AT&T Fiber. We will never again spend a dollar with Comcast or their kin.

No, we’re not bitter. Not in the least!

We have also had a couple of Tivo Stream 4K Android TV devices for several years. These initially overcame the fact that the Tivo DVRs had limited access to online streaming services. And the experience of using streaming services on aged Tivo hardware was less than enthralling.

Over the past six months the Tivo Stream 4K that we use most often has exhibited a problem. It would lose its connection to the handheld remote control. At first, it appeared that the remote was going through batteries very quickly. When the batteries failed the Bluetooth connected remote would drop the pairing to the Tivo Stream 4K. I’d put in a new set of batteries, and repair the remote. Mostly that got things back to working.

Extreme Power Over Ethernet

If you’ve been reading hereabouts for some time, you likely know that I am an advocate for power-over-ethernet. In it’s earliest days, almost twenty (!) years ago, I started blogging in order to share my experience combining working from a home office full-time, leveraging broadband-over-DSL and IP telephones.

SIP/IP telephones and Wi-Fi access points are natural gateways into P.O.E. That’s certainly how I got started. At first, I used POE insertors. As the number of POE-capable devices mounted, I migrated to Ubiquiti Unifi POE switches.

Smart thermostat goes offline: Not Cool

“I’m sorry, Dave. I can’t do that.” – HAL 9000

Back in 2021, we had an American Standard Platinum 18 air conditioner installed, with the accompanying Nexia 850 smart thermostat. We can control the thermostat locally, via their mobile app, via Home Assistant or its mobile app.

Early in the evening of November 24th I reached for my phone. I wanted to adjust the thermostat. On this particular occasion, the American Standard app on my phone reported a connectivity failure.

Rewiring the Network Core: Part 2 – Beats, Wi-Fi & Brittle Cables

As was mentioned previously, I’ve been upgrading the network installation in the central hall of our home. The new vertical rack cabinet is now installed.

The paint job is a little splotchy. A contractor we had working for us the other day commented on the “neat cloud effect” I had achieved. I had to admit it wasn’t intentional, but it’ll do for now. It’s mostly hidden from view. At least the color is a good match for the wall.

Vertical Rack

As you can see, power is still being supplied by way of a pigtail out the bottom to a nearby outlet. That’s temporary. It will be replaced by a wire fished through the wall.

You can also see the holes in the floor where network cabled once passed from under the house. I need to get wooden plugs to fill those holes. The cables now run into the wall, onward to the patch bay in the cabinet.
