To be clear, are you talking about a GFCI receptacle, or a GFCI breaker in your panel? A GFCI receptacle can definitely fail and still supply power without protection, and I would assume a breaker in a panel can fail in the same fashion. In either case, if the test button does not trip the...

Start with defining your process and a plumbing diagram. How many vessels, pumps, valves, etc. That gives you a starting point.

5 volt logic is primarily only supported by the MEGA anymore, almost all of the new controllers coming out are based on 3.3volt logic. Don't get too tied up in it when starting the build, as it will be easy to build that way from the beginning. Many devices output 0-5v, 0-10v, or 4-20ma...

Ideally, the more detailed the drawing, the easier it is to troubleshoot both onsite and remotely. I did an overview style drawing (plumbing), and I have the pin level for all my controllers. I developed and documented my wiring standard so at a glance I can look at any color wire and know...

I think what you are looking for is a "nested if statement". Once you see some examples of it, the logic should become clear.

Attach the drain/shield wire to a ground on one end of the wire only, preferably the panel/MEGA side. Chances are higher of creating a ground loop if you attach the drain wire at both ends, and that will just cause more problems.

I assumed the issue was with the bootloader file (bootloader_qio_80m.bin), so I pulled down the latest bits from Github for the ESP32. I swapped the latest of bootloader_qio_80m.bin into the resources folder but had no luck with it. For grins, I then swapped the bootloader_dio_80m.bin in...

Now I'm at a loss... using the Arduino IDE 1.8.13 in Ubuntu, I changed the flash mode from the default QIO to DIO and now it will load sketches properly. Using the esptool.exe program in Windows, it gives the boot error. I'll look further into the flags set in the InterfaceSetup script and see...

Well, it installed a sketch correctly one time, now its doing the same thing with the constant boot loop... I'll send it back and get a new one and we'll see what happens.

No dice on flashing, buttons are not closed and they respond as expected when pressed. I tried manually putting the board in flash mode but it didn't make a difference. The variant I have is a ESP32-WROOM-32E, these were released this year, possibly as recently at June. This appears to be a...

Ok, I'll mess with it a bit more. I don't have another on hand that isn't already flashed and the DevKitC variants seem to be a bit wider than the other boards so they wouldn't fit the shield anyway.

I found a screw terminal for an ESP32, but its the DevKitC version, so I picked up one of those boards as well. When I flashed it, it appears to have flashed normally, but in the debug terminal it looks like its stuck in a boot loop. Does a new firmware need to be cut for the DevKitC...

I'm guessing that the goto loop is negating the call function (assuming you are calling the MashRamp routine from somewhere else). If you aren't calling the routine from somewhere else, just comment out return and I'd bet it runs fine.

You need SQL Server Management Studio (SSMS), it's available from Microsoft.

Pretty sure we are talking about the same user here :) A couple thoughts I had, though I'm not sure how viable they are. 1) Variable log timing for individual globals/inspectors, or the ability to turn it off completely. Currently globals appear to log 1/sec (86400 rows/day). A quick look...

Has any work been done/considered on the DB side for purging/record retention? The SQL express editions only allow DB sizes up to 10GB; I'm currently sitting at about 7GB, and I'm aware of at least one instance where the DB hit its limit. In the latter instance, we had to blow away the DB and...

Could you realistically run your process by hand in the event of an automation failure? For my system and process, that's a hard no. Now, if you built your process such that the automation was running on top of your manual efforts, then sure, having some manual controls (3-way Auto-Off-Hand...

Find an old wall wart with a barrel jack that fits the mega. Cut the end off and wire it to your 12v power supply.

I think it should be pretty close, mine reads 5.02v, so I'd think +/- a couple hundreths.

Check the part number on your regulator and pull the data sheet. Mine is an AMS1117-5.0. It outputs 5v regardless of input. I'd imagine the chip on your mega should be of similar spec, so if it's not outputting 5v stable, you have a problem.
