SEN55 Air Quality Sensor with ESPHome and Home Assistant Tech Dregs 2024-03-10 | The SEN55 by Sensirion is an air quality sensor that measures temperature, humidity, volatile organic compounds (VOC), nitrogen oxides (NOx), and particulate matter at the PM1.0, PM2.5, PM4.0, and PM10 levels. You can also use the SEN54, which does everything but NOx. These sorts of devices are potentially useful if you do 3D printing, painting/epoxy, or just general air quality monitoring in your home.These work on a simple I2C interface, so can be integrated into Home Assistant very easily using ESPHome, which already has a component set up for them.While I use an e-paper screen for this, I would recommend just a regular LCD, as you probably won't be running this off of battery anyway given the power requirements of the SEN55.YAML and STEP files: github.com/techdregs/SEN55-Air-Quality-SensorTech data: sensirion.com/products/catalog/SEN55PR for the Waveshare 4.2 rev2.2 screens: github.com/esphome/esphome/pull/6209=== Timestamps ===00:00 Introduction02:00 Sensitivity and VOC/NOX indexes03:55 Power and display recommendations05:03 Shoutout to Mrmdavidson on github06:30 3D printing results08:45 Components and build notes12:30 YAML overview15:50 Conclusion

Voice Control and Wake Word Detection on USB Speakerphone in Home Assistant Tech Dregs 2024-03-02 | After way too many months, I finally have a USB speakerphone working as a voice control device on Home Assistant.

This one has much better audio properties, and it's plug and play (in theory).Set up on this one is dirt simple (if it works). Plug in the device.

Making an E-paper Dashboard with ESPHome Tech Dregs 2024-02-24 | Using Home Assistant and ESPHome to make a custom e-paper (e-ink) dashboard. The hardware is pretty trivial... the code is where all the magic happens. This can serve as a demo of using the Waveshare E-paper displays, displaying weather or other sensor data from Home Assistant, using the graph component, finding and mapping custom MDI icons, drawing boxes, formatting dates/numbers/text, and general display setup in ESPHome.I'm using the Met.no weather integration, and the method for extracting weather forecast data has changed in recent Home Assistant updates (2024.2). You have to create a template to run weather.get_forecasts to extract hourly/daily forecast information into sensors for use in ESPHome.Hardware used was a Adafruit Feather V1 ESP32 and a Waveshare 7.5" epaper screen.github for yaml and step files: github.com/techdregs/E-Paper-DashBoardWeather icons are from Google MDI, and here's where I found the codes for any custom icons you want to include in the code:I was inspired by seeing Madelena's project: community.home-assistant.io/t/use-esphome-with-e-ink-displays-to-blend-in-with-your-home-decor/435428MDI TFT file: community.home-assistant.io/t/display-materialdesign-icons-on-esphome-attached-to-screen/199790/16=== Timestamps ===00:00 Introduction04:11 Hardware08:18 Assembly Interlude10:45 Set up Weather Forecasts14:40 ESPHome YAML Highlights21:10 Conclusion
So were shaking our coffee now? Tech Dregs 2024-02-10 | A quick test of shaking vs WDT on espresso extraction, inspired by Lance Hedrick's videos. I do not find any statistical difference in extraction between shaking or WDT for distribution. I do think it's easier to pull off consistently, however.The dosing cup I use (not an affiliate link) is a CBSC: amazon.com/Dosing-Stainless-Coffee-Espresso-Machine/dp/B095NW254VI'm using a homemade WDT tool, Ascaso Dream PID machine, Eureka Mignon Crono with espresso burrs, 19g dose with ~45g output, IMS basket, extraction measured with an R2 Extract.Original LH video: youtube.com/watch?v=OyUaCuoqYWcHis followup: youtube.com/watch?v=5ivwCm95nLcMy previous big WDT test: youtube.com/watch?v=5MbV0iv0XRUMy followups to this video:youtu.be/5nQgo0BHWiQyoutu.be/8iGhlvZEcfIyoutu.be/UDx6aKO906s=== Timestamps ===00:00 Introduction00:37 Some comments on technique04:10 Test Parameters05:40 WDT Results06:12 Shake Results06:30 Extraction Variability06:58 Shot time07:12 Statistical Test08:20 Post-test Conclusions

Easy Solar Outdoor Weather Sensor with ESPHome and Home Assistant Tech Dregs 2024-02-02 | This will capture temperature, humidity, barometric pressure, and soil moisture. It uses a generic 5V 3W solar panel from Amazon (exact model no longer available), a 180mAh LiPo battery, a Seeed Xiao ESP32-C3, a BME280 sensor, and a capacitive soil moisture sensor.

The Problem with Ninja Nutri-Blenders Tech Dregs 2024-01-27 | A look at two big issues with the way Ninja single-serve blenders are designed. They develop leaks and they are a PITA to clean appropriately. The way they design their seals makes them difficult to remove without damaging (over time) and if you just put them in the dishwasher, they don't get clean.I'm replacing this one with a Vitamix. === Thumbnails ===0:00 Introduction1:21 Long-term brief review2:15 The first problem2:57 The second problem4:05 What causes leaks?5:30 Summary
ESPHome OTA Updates for Deep Sleep Devices Tech Dregs 2024-01-15 | Two methods for OTA updates of sleeping ESPHome devices. These devices can be quite hard to catch awake for firmware/YAML updates... so, here are a couple of ways to do it. The first is automated using some built in Home Assistant tools, but I only know how to do that for ESPHome updates. For configuration updates, there's a manual method using a Home Assistant Helper to tell the ESPHome device to stay awake next time it wakes up.The second method is the one I prefer. I got it from stevemann (Stephen Mann) on the HA forums.

Fancy Pants... for hunting (Sitka vs. Kuiu) Tech Dregs 2023-12-08 | A little comparison/review of the Sitka Traverse (Optifade Subalpine) and Kuiu Attack (Loden) pants. Both are fairly premium, mid/light weight hunting pants. Both have good construction. The Kuiu seem a bit heavier and might hold up better to brush. The Sitka are a little lighter and more roomy. I prefer the fit and comfort of the Sitka, as the way the Kuiu pants are cut is not very comfortable, and I think they are a bit too long for their sizing.Both pants purchased with my own money, and I have no connection to or affiliation with either of these companies.=== Timestamps ===00:00 Introduction01:38 Pricing02:55 Weight03:49 Sizing/Measurements07:21 Pockets and stitching14:15 Material and Noise16:32 Fit and overall opinions
