  • I have an ecobee thermostat that I manage locally over WiFi using the HomeKit integration, but I’d stop short of recommending it to new users.

    1. Ecobee used to support developer access to their cloud API for controlling the thermostat and collecting efficiency data, but stopped issuing new API access tokens in the last couple of years. They have no plans currently to reopen developer access. If you have a token then the ecobee integration works fine, but if you don’t you’re stuck with HomeKit.
    2. The thermostat requires 24V from the furnace to run the display and wifi stack. They provide an adapter you can install if you have available free leads at bother ends of the thermostat control cable. I had to splice a new wire onto the 24V transformer in my furnace since it didn’t have a 24V common terminal on the control block. It wasn’t hard to do in the end, but it was a lot of research.
    3. Some advanced thermostat features require the app. I am not sure whether the app uses cloud or local control when on the same WiFi.
    4. Not all features are available through the HomeKit integration. I can change the thermostat mode among Auto/Heat/Cool/Off, manage the blower fan mode and manage the heat/cool set points.
    5. Data logging. The damned thing does log activity back home, and the data is only available in the app or on thr web portal.

    Other than that, Mrs Lincoln, how was the show? I haven’t been unhappy with the ecobee. The HomeKit integration works fine, and I get enough data from the native HA history to track and manage my energy demand. I shied away from Honeywell because my last Honeywell thermostat-- the one I used just before the thermostat I replaced with the ecobee-- tended to cycle my furnace too fast during cold snaps, and it would put the system into thermal protect mode. There was no way to widen the hysteresis (or modify the duty cycle) except by manually setting the temp high, run the house up to that temp, and then lower the setpoint and let the house take longer to cool.

    ETA: the ecobee a decent thermostat and I’m happy enough with it overall. It has “spousal approval” accreditation as well. I wish it checked more boxes for me*, but it was essentially free through a power utility program. Its a worthy upgrade for me, but YMMV.

    * namely, Z* protocol local control and continued cloud API access


  • Termux (on F-droid) is a userland environment that runs on top of your Android device’s kernel. It has Debian/Ubuntu-like package management system that pulls from repos maintained by the termux team. If the package is available for aarch64, its probably available in the termux repos. Its not so much of an app as it is an alternate userland that runs on top of the same kernel, but can interact with Android a couple of different ways.

    The main Termux app gets you a basic command line environment with the usual tools included in a headless Linux install. From there you can select your preferred repos, do package updates, installs, etc, just like on a desktop or laptop. You could even install a desktop environment and use RDP to access it.

    Then there are some companion apps that are useful:

    • Termux:boot is like a primitive rc.d feature that executes upon boot up any scripts found in the termux ~/.termux/boot directory. You could use the feature to launch an SSH server, or perhaps start your syncthing service when the phone starts up.
    • Termux:Tasker is a Tasker plugin that allows Tasker to launch scripts in .termux/tasker based on whatever triggers or profiles you define in Tasker. For example, stop or start selected services when connected to your home WiFi
    • Termux:API is a set of termux utilities to interact with the Android API, and do things like send messages, interact with the camera or battery, and manipulate system settings.

    So you could install the syncthing package in Termux and (after setting up Termux access for your internal storage) configure it to sync folders from your phone to wherever syncthing syncs. You’d set up a start script under Termux:boot to launch it when your phone starts, or Tasker to start/stop the service on your home WiFi.


  • For the F-droid enabled users, it seems there’s a Syncthing app in the Termux repos:

    ~ $ apt show syncthing
    Package: syncthing
    Version: 1.28.0
    Maintainer: @termux
    Installed-Size: 26.4 MB
    Homepage: https://syncthing.net/
    Download-Size: 7857 kB
    APT-Sources: https://packages.termux.dev/apt/termux-main stable/main aarch64 Packages
    Description: Decentralized file synchronization
    

  • No worries, the other poster was just wasn’t being helpful. And/or doesn’t understand statistics & databases, but I don’t care to speculate on that or to waste more of my time on them.

    The setting above maxes out at 24h in stock builds, but can be extended beyond that if you are willing to recompile the FTL database with different parameters to allow for a deeper look back window for your query log. Even at that point, a second database setting farther down that page sets the max age of all query logs to 1y, so at best you’d get a running tally of up to a year. This would probably at the expense of performance for dashboard page loads since the number is probably computed at page load. The live DB call is intended for relatively short windows vs database lifetime.

    If you want an all-time count, you’ll have to track it off box because FTL doesn’t provide an all-time metric, or deep enough data persistence. I was just offering up a methodology that could be an interesting and beneficial project for others with similar needs.

    Hey, this was fun. See you around.



  • #### MAXLOGAGE=24.0
    Up to how many hours of queries should be imported from the database and logs? Values greater than the hard-coded maximum of 24h need a locally compiled `FTL` with a changed compile-time value.
    

    I assume this is the setting you are suggesting can extend the query count period. It still will only give you the last N hours’ worth of queries, which is not what OP asked. I gather OP wants to see the cumulative total of blocked queries over all time, and I doubt the FTL database tracks the data in a usable way to arrive at that number.






  • Sure that’s easy. All you need is an HX711 sensor load cell amplifier taped to the floor of the chamber where it sits under an edge of your bottle.

    Full, 5 gal (US) jug or water weights 40lbs nominal. If you have the same bottom feed dispenser I have, it starts drawing air with about 16-20oz of water left in the bottom.

    You’d want to calibrate first for the sensor without weight (tare), and then for a full bottle’s weight (40lb) accounting for cosine error of the bottle being slightly tilted by the thickness of the sensor. Or, tape a couple of shims at 120° offset from the sensor to level out the bottle.

    Finally, note the weight of an “empty” bottle with that 18ish oz of water in it, which will probably be close to the zero value.

    Now you can calculate % full by looking at the ratio of the current weight between your full/empty value as:

    %Water = [ (W_full - (W-18oz -W_tare) ) - W_now ] / (W_full - (W_18oz - W_tare) ) x 100


  • I can’t speak to the quality of actual locksets or recommended any products, but LockPickingLawyer on YouTube has a number of short videos discussing smart locks. My impression is most of them are trash at just being a lock. The ones made by traditional lockset manufacturers probably aren’t generally good at being smart, but I’ve been wrong about major brands’ commitment to open standards before.

    Assuming you can find a decent lock that talks Z-Wave, I think you’re on the right track with Zwave2MQTT and a USB dongle. I’d be squeamish about using a Pi specifically in a mission critical security control system for a couple of reasons (reliability, complexity, WiFi interference), but as long as you have keyed backup, it’ll probably be OK.

    I’ll leave it to others to recommend the locks, but as I mentioned in another post her, most battery operated Z-Wave devices, in my experience, report their battery life. Most of mine seem to go from 100% to 70% to dead in about a day though, so accuracy might be hit & miss.

    Maybe just leave one door with an old school keyed lockset as a plan B.




  • I used to selfhost more, but honestly it started to feel like a job, and it was getting exhausting (maybe also irritating) to keep up with patches & updates across all of my services. I made decisions about risks to compromise and data loss from breaches and system failures. In the end, In decided my time was more valuable so now I pay someone to incur those risks for me.

    For my outward facing stuff, I used to selfhost my own DNS domains, email + IMAP, web services, and an XMPP service for friends and family. Most of that I’ve moved off to paid private hosting. Now I maintain my DNS through Porkbun, email through MXroute, and we use Signal instead of XMPP. I still host and manage my own websites but am considering moving to a ghost.org account, or perhaps just host my blogs on a droplet at DO. My needs are modest and it’s all just personal stuff. I learned what I wanted, and I’m content to be someone else’s customer now.

    At home, I still maintain my custom router/firewall services, Unifi wireless controller, Pihole + unbound recursive resolver, Wireguard, Jellyfin, homeassistant, Frigate NVR, and a couple of ADS-B feeders. Since it’s all on my home LAN and for my and my wife’s personal use, I can afford to let things be down a day or two til I get around to fixing it.

    Still need to do better on my backup strategies, but it’s getting there.




  • I’ve been happy with the GE Enbrighten series, though they do require a neutral wire. I use the Z-Wave models, but I can’t imagine the ZigBee models would work any differently.

    Neat feature of the Enbrighten line is they recognize several gestures including short tap, long press, double tap, and I think even triple tap. I configured mine so that short taps on/off toggle the lights between off and 100% on, long press on/off brightens/dims, and double tap on activates the preferred evening lighting scene.

    I think Minoston are also a GE product line? Again, Z-Wave, but rated for higher wattage in my case. They also require a neutral wire.

    I had a pair of no-neutral ZigBee switches sold as ‘Martin Jerry’ brand, but they were super dodgy. Terrible feel to them, and they made a sort of electrical whine when the fixture was on. I pulled them right out and sent them back.



  • You could source a pair of gigabit media converters and a length of fiber on Amazon for about $100. Just use the media converters to extend the Ethernet port from where the Internet hands off in your house over to your office. You can affix the fiber along baseboards and up over door frames with adhesive cleats and zip ties, or those nylon staples on a nail they use to tack down coax cable.

    If you’re willing to spend a little more on the fiber for a custom color, you can probably even order the fiber in a more neutral color than SMF yellow to blend into the trim better.
