We've looked at a couple Outposts, Woodman's, and Pic'n'Save. I gather a major supplier has stopped providing TVP. Where are folks finding TVP in the last little bit?

I had this stuff set in my platformio.ini for the ESP32-C3/Arduino on a super-mini-dev-board and learned a couple things.

1. If the USB serial port is not open to a terminal, the ESP seems to be really sluggish.
2. If the USB is not connected at all, and the board is powered via the 5V pin, the board doesn't work at all.

By remarking all those defines out, the problems went away. I'd have to turn them back on to see my seria

Odds of getting a requested key seems really low, 1 in 4 or less, with or without a key. Is glyph hacking the only way to get more keys with any reliability?

Does anyone have experience with week-ish long summer soccer camps at Uihlein or the ones in Franklin? They are pretty expensive ($500+) relative to the amount of time, so I wonder about the value.

Has anyone attempted to use the Arduino BLE Scanner under very crowded conditions?

Tonight I attempted to run an outdoor game where players approach four separate ESP32s with designated BLE Beacons. The ESP32s each have a list of all the beacons and will display a clue once a known beacon's signal becomes strong enough.

This worked fine for the first hour but then the crowd really started to thicken. Standing in any one place with a phone BLE scanner I could see about a 1000 BLE addresses within just a few seconds.

What I found was that two ESP32s that were more in the thick of the crowd could not stay up. They kept rebooting or locking up. Two other ESP32s that were somewhat remove

I had kept meaning to look at ESPHome but never really got around to it. But now I have an Arduino sketch with an intermittent problem that I absolutely do not have the time to deal with. The sketch is little more than a converter between the MCP23S17 and MQTT, but something is wrong. It will run for hours, but not days.

I'm impressed that with a few hours of learning I was able to knock together a yaml that almost completely replaces my sketch. Even my special MQTT command that made the controller re-publish all the states of all the switches could be specified by using a mix of actions, substitutions, and lambdas.

I'm hopeful this proves to be stable over long time frames. If nothing el

I am a newb to ESPHome and am trying to use the MCP23S17 component.

However, when I compile, the compiler complains that the mcp23s17 component is not found.

Is that component in some special version of ESPHome or require some extra setup that the documentation doesn't mention? The compiler says it is v1.15.3. I installed it tonight.

I saw in a github issue somewhere that you can poll the AI enabled Reolinks to get the person detection status. I'm curious if anyone here is doing that and whether or not it works well.

Do any of you use the WT32-ETH01 with any regularity? I'm wondering if they are just unreliable.

I got a few of the WT32-ETH01 modules from AliExpress. I built a board around one. A few minutes of research turned up the procedure to get the ethernet module going. That procedure seemed to work great.... for about 10 minutes. Once I had the Ethernet going I re-flashed a few times troubleshooting application level issues with my sketch. Then, on one flash, the PHY wouldn't initialize. It gave the same error as when I had the PHY address wrong and wasn't turning on IO16. Changing sketches back to the simple ethernet example where I initially verified what the correct PHY init procedure didn't

I'd really like to get a stream of images out of a common webcam at 30fps. I can take a pretty big hit in quality. Maybe as far down as 160x120 resolution.

The problem I have is that, with the two cheap webcams I have, both seem to ignore frame rate and probably resolution commands. Both their behaviors are the same regardless of setting: Variable 5 to 30 fps depending on scene complexity. Just a face is 10 to 15 fps, a face with stuff in the background is 5 fps, whereas a sheet of paper is 30 fps. It doesn't matter a bit whether resolution is set to 640x480 or 160x120. The result is the same.

I've tried both Qt 5.7 (QtCamera class) and OpenCV (VideoCapture class) (which appears to use th

I'm looking for a goldilocks image that will have a semi-recent Mosquitto (1.3+) and have Oracle's Java8 on tap in the package manager without having to add package sources (e.g. edit system files) or compile.

I can plow through myself, including compiling Mosquitto. But I'm looking for a simpler process that would be easier to share with others. I figure two install lines plus all the OpenHAB stuff would be manageable for a lot of folks.

I'm downloading various Loboris images now that I'll just write down to a card and try, but I thought I'd ask if anyone just knows the answer. -Thanks
