Just spent a half hour looking at Milk-V Duo S on Amazon and a video - looking great ... until ... the video. He couldn't get I/O to work. One onboard LED blinking. And that was it <sigh> looking soooooo promising. On a side note digging through my 5 tons of (gee I might be able to use that some day ...

OK - detail. Sundance hot tub. The controller board is ... ??? flaky ... runs great - until it wanders off and stops heating. A replacement board is ? $700. The company that makes it "we don't share schematics". Even if I spent the money the only visual/control is a top side display and buttons - no ...

Thanks - sort of - my problem is the spread sheet - with #2 you get eggroll - like taking a starving person to a restaurant and handing them a 23 page menu

I'm starting a project and I'm requesting a recommendation as to which ESP32 to use. Requirement 1: control an 8 port relay board (ie ELEGOO 8 Channel DC 5V Relay Module). Req. 2: input temperature (ie DS18B20) x4. Req 3: display web page - temps, relay control

Thanks.

Seems there is more than one software load I can upload to my ESP32-cam. I want to run off a solar/battery - which software will use the lowest current draw. Or does it matter? Thanks

OK, so I've read that a ESP32-cam draws 180mAh. If I use a 30000ma solar battery bank (amazon $25) my math says 166 hours. https://www.youtube.com/watch?v=0uz-YrfaSO8 says by using 2 18650 batteries he get 24h+.

If I wanted to construct a solar powered ESP32-CAM - how much battery would I need to last all night? And has anyone already invented this wheel?
Thanks

There's a package, Zoneminder, a open-source video surveillance software system. It allows you to describe an area of the image to alarm on, how long to record, to send a message. Some time back I set up a Raspberry Pi Cam, added it to Zoneminder and it just worked. I'm now trying to get a ESP32-CAM ...
