Problem with triggering off INA226 value near startup

[pkkrusty]

Still working on figuring out exactly what's happening, so haven't started an issue yet, but this doesn't occur on an identical system running 10.0.0.3, but does occur on 11.0.0.3

I have an INA226, a seven-segment display and two relays. If I have a rule that triggers immediately on startup like on ina226-1#voltage>20.5 do power2 1 endon (and INA is actually reading > 20.5v) the system bootloops on restart 1 or a normal powerup until the failsafe happens that turns off the rules. If the rule doesn't trigger immediately, the system boots normally.

However, I have another ruleset that triggers off INA226 voltage and current values to send data to the display, and that does not crash the system on boot.

Rule1
On system#boot do backlog power3 1;ruletimer3 10 endon 
On ina226-1#Voltage!=var1 do var1 %value% endon 
On ina226-1#Current!=var2 do var2 %value% endon 
On rules#timer=3 do backlog displaytextnc %var1%; ruletimer2 2 endon 
On rules#timer=2 do backlog displaytextnc %var2%; ruletimer3 2 endon

Ruleset 1 works normally

Rule2
On ina226-1#voltage>20.5 do power2 1 endon

Ruleset 2 crashes the system

Both relays are on safe GPIOs (12 and 13). INA226 is on safe GPIOs (4 and 5).

If I change Rule2 to something that doesn't trigger on startup, like On ina226-1#voltage>23.5 do power2 1 endon there's no issue.

Am I missing something basic? I don't think so since this all worked on 10.0.0.3.

I swapped the TM1637 from RX/TX gpios (so I could capture serial log data) to GPIO0 and GPIO2 and the problem has not reoccurred. Not sure why that would have fixed the problem...

Was it the pin swap or powering through USB that solved the problem ?
ie does it still crash when the TM is on 0/2 and still powered by your external PSU ?

5.05V is almost no difference to 5V. Most 5V parts would accept +5% or +10%.
I don't know the board you are using but if it happens to have a true AM1117 regulator, it can support up to 15V input.

If you have to time to investigate more, I would set it back in the configuration that crash and try to do replace the POWER command un ruleset 2 by a dummy command like setting an unused variable. If this does not crash, I would then try with Power2 1 but without the Relay 2 connected.
It may be possible that you power the relay early at the same time the ESP is trying to connect to Wifi which is when its power consumption is the maximum. That could make your power circuitry fails somehow.

I've been powering my Wemos Mini D1 knockoffs with 5v directly to the 5v pin lately since powering them with USB tends to drop my 5v down too low to reliably activate mechanical relays (probably due to crappy regulator).

I had to pin swap to deal get serial log data. However, these 'relays' are MOSFET PWM boards, so the current draw is even less than the 50mA that a relay would take (I think). I did disconnect them to rule out funny business, but it made no difference.

It's running fine with the TM1637 on GPIO0/2 and powered via the external PSU at 4.92v

Just defined the TX/RX as CLK/DIO respectively, and it crashed in the same manner. Seriallog was set to 0. Seems crazy that the display mapping to TX/RX would crash on a non-related trigger.

ok, here's the serial log output on a crash cycle...

Looks like it's the display doing it. Or is it the INA226 which initializes directly after the display...

Hmm, now I'm thinking it's crashing on any active ruleset that's too long. I wonder if my flash memory is bad.

Rule3 
On time#minute=1 do power1 1 endon
On time#minute=2 do power2 1 endon
On time#minute=3 do power3 1 endon
On time#minute=4 do power1 1 endon

On time#minute=6 do power3 1 endon
On time#minute=7 do power1 1 endon

On time#minute=9 do power1 1 endon
On time#minute=10 do power1 1 endon
On time#minute=11 do power1 1 endon
On time#minute=12 do power1 1 endon

crashes, but

Rule3 
On time#minute=1 do power1 1 endon

does not.

will swap dev boards tomorrow and see if I can reproduce the problem.

Swapped boards, but same problem occurs. Leaning towards a power issue, since I can't reproduce the problem powering the dev board via USB.
