Hello to everybody! I am moving my mini-SCADA for heating system from ESP8266 to ESP32 and I am going to work with ESP32 WROVER kit. This is an upgrade, as I've hit the wall with ESP8266, and as a bonus there is ILI9341 display mounted to WROVER KIT. I have been reading about LittlevGL, this is a gr...

Hi guys! I see there was much activity on this forum when I was partially unavailable. This gives me good feeling about community and platform! To the subject. Stability or stability + WDT as it was described here remained unchainged, so my setup is stable, small software WDT with timer did the tric...

Kevin was right. I have been silent here on forum for last few days, almost 2 weeks. I have been testing. So this is what I have learned. First 5-6 days, crashing/freezeng continued, and my ESP8266 froze about once a day, and allmost allways in the time when pumps and mixing valves were in full oper...

In general, after few days of testing, I have now, about 1 freezing/crashing per 24h. There is no 'error' in logs (condition that is catched by try as exception). This is also not acceptable, I want the ESP8266 to be able to control heating, that is pumps and mixing valves; two pairs of those (two p...

I’ve done some adjustments to code, more of gc.collect etc; more of the machine.reset and got full stable 24+ hours of work, everything fine. But, I have identified one part of problem. Power supply. As PS is very close (on the same cable) to water pumps (low power; used for heating; about 100-150W ...

Peter, Seems like you know your way around this, thank you! About choosing board and power supply. I’ve bought few $5 NodeMCU boards from AliExpress. I can’t say I have put much of a thought into that. Could you please advise me towards which boards would be more stable/better? Would Olimex/Adafruit...

Hello! Just wanted to ask here, in the ESP32 subsection of forum. I have opened another topic here: https://forum.micropython.org/viewtopic.php?f=16&t=5517 The thing is; my ESP8266 after ~10 hrs of working quite fine; doing one HTTP POST request per minute is crashed/frozen/not iterating through mai...

I've thought that it is something like that; something with shortage of memory in some way. But, if this is the case; this is part/problem of MicroPython implementation? This does not make me appreciate MicroPython for ESP8266. I am going to ask in the ESP32 subsection of forum is this also the case...

Thank you Kevin! I have been doing machine.reset every 2 hours, still got frozen/crashed device after about 10 hrs. Do not understand what am I doing wrong, if ESP8266 is so popular for IOT solutions, how come it is crashing after few hours of work and 60 HTTP POST requests per hour. If I understand...

I'm working on prototype, ESP8266 (NodeMCU), MicroPython. I'm not new to software developement, microcontrollers etc. but am new to ESP and MicroPython. Previous implementation was on Raspberry PI, proven to be stable during course of 10 months. As Pi is quite an overhead; I'm now trying to use ESP8...
