Can anyone explain these annoying outlier points from my zwave thermostat? This is from a honeywell thermostat, but before this I had a trane that suffered from the same problem. It happens with current temperature and humidity. It’s not like its terrible, it doesn’t mess with my automatons or anything, but when I want to...
This is fairly common with remote sensors. Some are perfect and exist in a perfect system, some do not. I am going to rattle off some of the first things that pop into my head…
Honestly, there are a thousand reasons that you could miss a data point every once in a while. Just looking at the chart, it is still sending a data block but the humidity just reported low for a second. Maybe the thermostat is not getting a data block and filling in the data based on its own clock.
Compare it to other data and see if the system turned on or off. Electronics can be sensitive to power drops and it wasn’t able to feed power to the part of the board that manages the sensor for a second. Maybe there is a condition where a capacitor gets fully discharged for a second and is pulling all current away from the sensor. (It’s usually an analog signal from sensors and maybe a measurement of resistance that translates to temperature or humidity. A voltage drop would significantly impact a reading.)
It could be a timing glitch with the code where it can’t read the sensor but builds the data block anyway. Depending on how the sensor works, it could be trying to compute the data the second it gets polled for data and it has nothing to give.
It could even be the wiring to the rest of the system. HVAC systems vibrate and a screw might be getting loose. It could be a cold solder joint, even. What is to commonality between the two thermostats that you had?
The list goes on. I have always treated sensor data as unreliable. Heck, I have a couple of CO2 sensors that do the same this as what you are seeing here. Every so often, the just report zero for a second.
Mesh protocols like zwave and zigbee aren’t 100% reliable. It could be local interference with the signal.
Without some extensive debugging and the willingness to disassemble your thermostat, just treat it as an annoyance.
Edit: I was looking at this from an American perspective and assuming these were all 'murican ships and aircraft. There aren’t. Nothing I previously wrote would align with the video since the British navy is weird. So, I just erased my assumptions. They were likely all wrong anyway.
That explains my confusion. Something looked really off and and my brain couldn’t compute what I was seeing, TBH. The elevators looked right, but I still wasn’t sure.
Edit: There more. Is that whole group British? The last two fixed wing aircraft that fly by aren’t 'murican either. I see a Black Hawk-type helicopter, I think. We use SH/HH-60s in our Navy that have their rear strut moved way forward. The British and Americans both use LCACs as well. The leading helicopter might actually be a Merlin followed by some Wildcats. Alas, all I can make are stupid guesses now.
I learned a lot running a drop shipping based novelty store for a bit and it seems that human sexuality has very few boundaries. As long as nobody gets hurt (unless that is their thing) and everyone is of age, people should explore what they want to explore.
I made a little bit of a joke about that in my last comment, but it was just superficial. It’s someone’s thing and they have every right to get off how they choose. (TBH, the people I met that were on the extreme side of things were very open and had a good sense of humor about it.)
in charlie and the chocolate factory (2005) (the best version imo b/c i saw it as a kid and the magic only works around then) a lady said that chocolate is an aphrodisiac and i’ve completely internalized that as true....
That myth is still pushed by many TV shows to this day, unfortunately. I believe that most public emergency defibrillators work automatically, so that is nice.
It’s possible, especially when it comes to things like luck or illusion. Most people know that magic isn’t real, but some still tend to fall back on magic as an explanation for a really good illusion.
There is a fine line between holding two beliefs that are in direct contradiction and understanding that something you want to be true is something that you also understand is a misconception, is my point.
There is a term for things like that: “mental gymnastics”
People can naturally hold conflicting ideas or sometimes feel the need to believe things they know aren’t true. It’s extremely important for people to become more self-aware in that regard as it is something that can be exploited by religions, politicians, cults or scam artists.
Everyone is vulnerable to it, to different degrees. Even in the privacy of our own thoughts, most of us have tried to convince ourselves of something that wasn’t true, regardless of any facts we have seen. It’s just human nature.
My current setup has my DHCP + DNS on my Unifi USG. However, as I have all my apps hosted on a different server (unifi, plex, home assistant, NAS, etc.) I’ve ran into issues trying to get things set up....
Meh, I didn’t mean to hate on DHCP. It’s just a service I have learned to keep running all by itself somewhere in a dark corner of my network. DNS and DHCP are just services that I don’t like going down. Ever.

I’ve been reading Mastering Regular Expressions by Jeffrey E.F. Friedl, and since nobody in my life (aside from my wife) cares, I thought I’d share something I’m pretty proud of. My first set of regular expressions, that I wrote myself to manipulate the text I’m working with....
Yeah. The only one you really need to care about (especially under Linux) is PCRE, the good 'ol Perl Compatible Regular Expressions. For the most part, every other flavor is a derivative of that. Microsoft had a weird version for a while, but that may be completely dead now, thankfully.
Learning the syntax of regex is fairly easy. Hell, I still have to use this cheat sheet more often now that my perl skills are no longer needed or even relevant.
Regex isn’t that hard. The challenge is identifying and understanding patterns in the data that you are filtering. Here is a brain hack: As an example, if to have pages and pages of logs that you need to filter, open up one of the log files, stare at the screen and hold the page down key for several dozen pages. Patterns can be easily seen in the blur of text that is quickly scrolling across the screen. (Our brains love to find patterns in noise, btw.) The patterns that you see will give you focus points for developing regular expressions to match. ie: You start breaking strings into chunks and seeing the ebb and flow of data streaming across a screen helps. Anomalies in the data “stream” are are easy to spot as well.
From a security and efficiency standpoint, you should also understand where the most processing takes place so you don’t kill whatever platform you are working on.
Sorry for the rambling, but I am getting older and feel the need to pass on a ton of tips and tricks whenever I can for these “archaic” languages.
Asking being I just had take out about 40 screws and disconnect several board connectors to replace a simple damaged motor gear. Took a few hours for something that could easily take minutes to repair with a little thoughtful manufacturer design.
I just did a quick search on Printables and there are quite a few mods and replacement part designs out in the wild. After looking at my Roomba, most of the major parts look easy to reverse engineer and reprint if needed.
Just a quick note that Instance upgrades appear to break Connect. It’s no biggie! Just re-login and all is good. (Some of my existing connectons worked, some didn’t.)
