I'd like to make our front entryway lights motion sensing. However the wiring is a little complicated. And I'd like the lights to be operable normally if the automation doesn't work for some reason.

There are three light switches: one by the front door, one up the staircase at the landing, and one at the back of the entryway at another interior door. My favorite switch is the CloudFree motion sense switch, running Tasmota, but I don't see it or a similar switch available for three-way wiring.

There are two light fixtures: One hanging lamp, and one track light. The bulb in the hanging lamp is hidden, so although I could swap it out with something smart, it wouldn't be easy to just put a motion sensing bulb in there. And the bulbs in the track light are some small/unusual base, not something I can upgrade.

How would you automate the lights? Grateful for any ideas!

I have two type-k thermocouples with breakouts from Adafruit, attached to a ESP8266 (Huzzah I believe). My oven was very old and didn't come with a temperature readout or any kind of preheating status (but thankfully also no builtin WiFi). The Tasmota device reports to HomeAssistant, which stores data in InfluxDb, which I can then chart in Grafana.

Here you can see the internal temperature got to 151F, and I was surprised to see how much the oven's temperature rebounded after I took the cakes out, despite being off.

The recipe is "Chocolate Lava Cakes For Two" from NYT Cooking. It's one I make semi-regularly, pretty quick on a weeknight and delicious. I have small ramekins so the recipe makes three and they cook a little faster than the recipe's would.

First try I used AP flour and let the 1st rise go too long I think, and they were too dense. This time I used my regular sourdough recipe with bread flour (920g, with 650g water, 71% hydration) and they came out great.

Thanks for the inspiration from this community!

A 2020 Cochrane review that assessed the two clinical trials concluded that "whether adults see their dentist for a check‐up every six months or at personalized intervals based on their dentist's assessment of their risk of dental disease does not affect tooth decay, gum disease, or quality of life. Longer intervals (up to 24 months) between check‐ups may not negatively affect these outcomes." The Cochrane reviewers reported that they were "confident" of little to no difference between six-month and risk-based check-ups and were "moderately confident" that going up to 24-month checkups would make little to no difference either.

Likewise, Nadanovsky and his colleagues highlight that there is no evidence supporting the benefit of common scaling and polishing treatments for adults without periodontitis. And for children, cavities in baby teeth are routinely filled, despite evidence from a randomized controlled trial that rates of pain and infections are similar—about 40 percent—whether the cavities are filled or not.

Followup to temperature profile with a probe in the loaf. The temperature inside the dutch oven was lower and steadier than I expected.

Temperatures recorded in the oven during a dutch oven sourdough bake. 20 minutes at 500F with the dutch oven lid on, 20m at 400F with it open.

Green = oven temperature throughout. Blue = baseline kitchen temperature (thermocouple cold junction temp).

• Before 1st blue line: preheating. Yellow line = inside a cold cast iron dutch oven. Oven was already warm from baking something else.
• 1st blue line to 2nd: baking with lid on. Yellow = probe in the loaf here onward. I was surprised the internal temperature has pretty much maxed out by the end of the first 20 minutes.
• 2nd blue line + 20 minutes: baking with the lid off.
• After 20:27 / green line dropoff: oven open, loaf cooling. I know you're supposed to cool to "room temperature", but even at 150F the crumb was pretty stable when I cut the loaf, with no obvious tearing or sticking to the knife.

Compare to the previous bake where I forgot to reduce the oven temperature after the first 20 minutes. The crust was black/inedible, but the interior was still totally fine.

I put three DS18B20s on a wire along with three SHT30s on D1 mini shields, all in a cardboard box indoors, for a day.

My conclusion is that the DS18B20s are actually more accurate. My Fluke's thermocouple also agreed with them.

The SHT30s all read several degrees higher, with the one that was at an angle reading a little lower than the others which were flat. When I turned them all on edge their temperatures converged a bit lower but still a bit high. I wonder if some of the spikes from their readings are just microcontroller activity.

I'm hoping to use the Tasmota TempOffset command to adjust.

The DS18B20 (on a Feather Huzzah) seems to miss some rapid changes that the SHT30 (on a D1 mini shield) reports, even though TelePeriod=60 for both. The DS18B20 does seem to report changes within 60s of each other sometimes so I think we're just seeing duplicate values elided, which I do expect.

The thermostat on the wall near them (which they'll be replacing) reports 70F, closer to the DS18B20. I have a thermocouple for my Fluke multimeter which I may try to calibrate in ice water and then use to calibrate the temp sensors, though I'm curious if there's an easier way; or I might not bother since I care more about just setting the climate for room comfort than specific numeric temperatures.

The data path is: Tasmota -> MQTT (Mosquitto) -> HomeAssistant -> InfluxDb. In this case the chart's just in InfluxDb's data explorer, though I have some dashboards in Grafana too (which was the motivation for having Influxdb).

I am thoroughly enjoying having Boost again, but I'm also definitely falling into a habit of scrolling for too long. It would be nice if Boost could help remind me to be done with Lemmy for the time being. One way would just be a limit in the number of posts that would load when scrolling down in the home view, probably configured via a setting.
