Relying on the cloud for home automation and monitoring

When I started getting into home automation 9 years ago, I decided to go with Z-Wave devices as it had the largest range of devices I could integrate into a system. Z-Wave communicates locally with a hub for automation and doesn't rely on the cloud to work. At the time I made this choice, there weren't many options let alone ones that relied on the cloud or apps to work. Fast forward a few years and there are a number of proprietary systems and apps that won't work without a connection to the cloud. This, of course, causes problems when the Internet is down, the provider is down, or the provider has gone out of business. Luckily my setups have never relied on the cloud (they have had some integrations for notifications and such, but the basic automations have been local).

Part of my home automation is monitoring power usage as well as solar production. When I had my SunPower system installed two years ago, I had researched how to monitor the system locally. I've written about my system and how I monitor it. While SunPower has their own app, I've never relied on it because it isn't integrated into the rest of my home automation setup. I was told by the installer that if there was ever a problem, they would be notified and would give me a call to come out and take a look. That shouldn't great, but I never really trusted that would happen as one of the panels wasn't activated when the system was turned on and because of my own monitoring, I alerted them to come out. I have no idea if they would have called me to fix the problem or I would have been out 1 panel of production.

If you follow the discussion of my article, you'll see that people have been reporting that the SunPower app isn't showing any data. I hadn't noticed, but checked and saw that the app hasn't recorded data for the last 1.5 months! Ouch. I don't know how SunPower or the installer monitors the system when it hasn't reported in, but I would have expected a call to fix the system. Luckily I don't rely on the app to see production. My nice dashboard in Home Assistant tells me production and usage without talking to the cloud. If my system had failed 1.5 months ago, it would cost me a significant amount of money and I would have been quite annoyed that SunPower didn't alert me.

I just used the app to change the device to connect via WiFi (it is still connected via wired Ethernet) and now the device says it is online. Will it work tomorrow when the sun is up? I don't know. Do I care? Not really as long as my non-cloud based system keeps working.

Side note

This year we may have turned a corner with relying on the cloud for various home automations. The Matter standard aims to join various systems and have local control over devices. Will this work out? I can only hope.

Eating my own words (again)

I've spent a little less than half my career self employed and the other half working for companies, so I'd like to think I know something about the pros and cons of both types of work. In the last two companies I worked, I said at the end of my tenure that I'd never work for anyone again and would always be self employed. That didn't work out for a number of reasons causing me to eat my words.

Being self employed sounds great as I didn't have a boss, no reviews, I could work my own schedule, and no one was looking over my shoulder. That was only partly true; as a contractor I always had to work on someone else's schedule and meet deadlines. In addition, I was sometimes the only person doing my type of work meaning I had to handle all the support, deal with all the issues, and sort of be on call all the time. Also any time I took off, I didn't get paid for meaning that it could be very costly (depending on the contract I could get paid for some vacation, but I always felt guilty about taking time off). Being self employed also means sending out invoices, hoping you get paid on time, stressing over raising rates, and crossing your fingers that your contract isn't terminated without notice.

One of the things that I missed when I was self employed last was working with other developers doing the same type of work, i.e. iOS or Mac development. This made it hard to learn new things as there was no one around to push me or show me better ways. No one was looking over my code and since I'm not perfect, I likely kept making the same mistakes over and over again.

This past April I started a new job and now work on a team with another 14 iOS developers. I pretty much learn something new everyday and know that I'm not alone when it comes to figuring out problems or tackling the work. Of course, I do my best at work, but it is much easier to leave work at the end of the day.

As much as being self employed sounded great, this change has been good to me and has lowered my stress. It has also given me opportunities to learn new skills and hone my existing ones.

Those words about never working for someone else sure tasted good!

Fixing Battery Drain in Kwikset Locks

Almost 10 years ago I installed Kwikset Z-Wave locks on our doors. They had been working well for years, but I noticed that the batteries drained faster than I had expected. I attributed this to buying refurbished or b stock locks and just tried to get batteries that lasted longer. Last December I decided to replace the locks with new ones that hopefully drained the batteries slower.

The locks appeared to drain slower initially, but I wasn't get the year out of a set of batteries that I had read others could get; I could get a few months. After one of the updates to Home Assistant, I noticed in the Logbook that it recorded Z-Wave commands. In the list of commands were a bunch of "lock" commands sent to one of the locks; about once every 30 seconds at night.

Ah ha! It finally dawned on me. In my Node-RED automations, I had it setup to lock the garage door lock at night if the door was closed. This was repeated every 30 seconds. I had thought that if the lock was locked, nothing would happen. That was not the case as Home Assistant happily sent the command causing the lock to wake up every 30 seconds. The fix was quite simple: before sending the lock command check the state of the lock as Home Assistant stored this without having to poll the lock. With this simple change I stopped seeing the Z-Wave lock command and knock on wood, the batteries are lasting longer!

Review: Ryobi Hobby Station (and a missed opportunity)

I love having the right tools for the job whether it is software tools or physical tools to tackle projects around the house. As I've mentioned before, I really like the Ryobi 18V One+ line of tools. I have a number of the tools and keep adding to my collection. While the tools may not be contractor grade, they are more than enough for my uses.

Last year they announced a number of new tools in their collection including a new Power Source that can charge batteries from USB-C as well as power USB-C devices. Unfortunately the product isn't available and I check Ryobi's website every few days to see if the "Coming Soon" button changes to "Buy Now".

A few weeks ago when I was checking the site, I noticed the Hobby Station which takes on of Ryobi's rotary tools and turns it into a drill press and holds the tool making it easier to use. This was a little expensive for what it was, but I decided to order it. Even though I don't own any of the rotary tools that Ryobi says works with it, I though that I might be able to use my P460 Rotary Tool Station with it if I screwed off the top housing. What I didn't realize at the time is that the diameter of that housing and the diameter of the tools that are designed to work with the station are different.

The Hobby Station arrived and I quickly set it up. When I put the tool in the holder, I found my mistake where the tool was too small. However, that didn't deter me. I screwed the tool in place and it gripped the rubber and seemed fairly secure. Perfect, I didn't have to return it!

Later I thought about the main nut holding the tool in place digging into the rubber and didn't like it. So I looked for a reducer bushing and thought I found an irrigation one at Home Depot, but realized that the threads probably wouldn't match. Not deterred by this, I asked my son if he could design a part and I could 3D print it. After a number of test prints, we had a working bushing! While it isn't an exact fit, the plastic is soft enough that the threads of the tools can dig into it and provide a fairly tight fit.

Now that I had a working hobby station, what do I think? For starters, the drill press has limited utility. With my solution, there is a bit of wiggle in the tool and frankly, how often have I needed a drill press? The station does hold the tool and make it easier for me to just hold the working piece. The angle adjustment is somewhat useful as I can see myself using it facing straight down or at a 90 degree angle. I don't know how much I'll use the fence that comes with it or use the vacuum attachment.

Pros

• Convenient way to hold a rotary tool
• Flexible angles to hold tool
• Appears well made

Cons

• Only works with some rotary tools
• Drill press has limited utility
• Over priced

Summary
This tool is definitely over priced and has limited utility for many people. It isn't a precision instrument which is needed for a drill press. It does seem like it is built solidly and will work for my needs; holding the rotary tool while I work on something is very useful for me.

Unfortunately I can't recommend this to others; I will keep mine, but there are probably better solutions out there. If Ryobi had included a reducer bushing to fit their other rotary tools, it may have been a more compelling purchase and would definitely increase potential buyers.
