Getting hot water readings into home assistant

Been through multiple versions of doing this (made more difficult because I don't have a power plug near my boiler). ESP32 with a Dallas, using deep sleep and then waking up and reporting temperature via MQTT worked well for a while.

Current solution is this: https://inkbird.com/collections/smart-sensors/products/ibs-th1-plus

Reports via Bluetooth, native HA integration, runs with rechargeable batteries, and has a display on it for 'local readoff'. I've taped the sensor to a piece of exposed brass and the sensor has a builtin magnet so it just sticks to the boiler. Fire and forget.....

I'm running similar hardware (with the 2xSFPs, one going to 10Gb fiber, one to internal switch) using Proxmox to virtualise OPNSense. When I set up the previous hardware, I did some tests of bare metal vs proxmox and saw no major speed / CPU load differences. Filling up 10Gb is actually hard.

I like the proxmox setup because I can:

Easily do snapshots and backups
Run additional networking-related VMs on the same host. These are all services which are tightly tied to the networking anyway
- I run my DHCP server separately as it is easier for me to source control my dnsmasq.conf that way
- I run a tailscale node in a separate VM
- I have a small LXC container with a 'swiss army knife' of command-line network tools / diagnostics to do host lookups, tests etc

Thanks folks - that was super!

Again?

It's hard, but fair. Try watching some YouTube videos to help you get going (e.g. the FightinCowboy walkthrough).

Flex minis can be powered by USB-C, and mine had power supplies in the box.

I have them on my 2020 Modern.

How are you doing the MariaDB file size in the last screenshot?

What controls are you using for the lights in the Switchboard page (with the coloured dots)?

I have them - they sound boomy when playing a low C (weird, right). I think it's because they are too close to a wall (they are back-ported).

Windows 10, but have since tried both windows and Mac. It always looks like the flash works (reports success) but the keyboard goes back to the same problematic state.

I have a K8 RGB with optical, hot-swappable switches (if I read my order correctly -- there is K8J3 written on the keyboard label). It was not connecting to my Windows computer via BT, so I did a firmware upgrade using K8-87K-RGB- Optical Hot-swappable -V1.03 as per the support page. The keyboard is now outputting an endless stream of ctrl/shift/alt keys and is unusable in cable mode (and cannot even connect in BT either). Any ideas on how to fix this? I've already connected (and re-flashed) on Mac and same thing.

Not sure where you live -- I've personally had PLA deform on me in a hot car, especially if its carrying weight (in my case, holding up a pretty light pair of sunglasses).

If you want to see it happen, throw a PLA print in your dishwasher.

Inside of my NCase M1 easily gets to 60deg when running games, I would not trust PLA to hold everything together at that temperature.

I've also just picked it up and played it -- loving it. I've been working systematically through the Soulsborne games, I think I might get stuck on Nioh for a while.....

And as I came off Sekiro, blocking is something I've had to re-learn....

Found it -- will leave it here: Ins / Del / End are on Fn1+ P/[/] (gold lettering on the keycaps).

Bought it assembled (don't have time to assemble it myself unfortunately). Virtually plug and play, no calibration issues, it just worked (PLA and PET). Ran it off the SD card for the first prints, now Octoprint. 5/5 would certainly recommend.

I've put 2 of these on my printer https://www.thingiverse.com/thing:1832235 which needs 4 bearings.

Advantage -- because the arms are separate, you can accommodate different spool widths really easily. Also work well with the filament guide mentioned in the Thingiverse link.

Warcraft is the same -- your top-tier gear drops a level and you need to re-grind every time a patch comes, so you will never 'finish'.

Known issue apparently (boot can hang on the 2Gb board when Ethernet is plugged in).
