Now I got 10W LED bulb, I will also test with USB instead of the 5V DC from the variable supply.

So far I can't replicate it but I am waiting to get LED bulb, only have regular incandescent bulb. Attached it to both relays. In this video it is attached to relay 1:

https://www.youtube.com/watch?v=kJwsUbcyFOY

My wires are longer.

I am using variable power supply for the ESP32-EVB, it draws around 1W.

This is my Arduino IDE code, I use Arduino 1.8.19 and latest ESP32 package for Arduino (3.2.0):

I initially tested with these LED light bulbs: https://manuals.plus/m/e8c22ed756cd0095734a658d5bff9f7aeb5089dcd9e156197a70f3c7d48e967c.pdf

"OSRAM LED BASE CLASSIC A" - 6,5 W - model number AC03079

As requested, I also switched bulbs and replaced the OSRAM with IKEA LED1934G3 bulbs: https://www.ikea.com/de/en/p/tradfri-led-bulb-e27-250-lumen-smart-wireless-dimmable-warm-white-globe-40439254/ they have 2,7W.

I have the same problem with the IKEA bulbs as with the OSRAM bulbs

Last post by LubOlimex - May 06, 2025, 08:49:00 AM

Maybe it can be a problem or bug in the older libraries in ESP32 for Arduino IDE?

Maybe adding a delay before Ethernet initialization might fix it. The thing is that the ESP32 chip needs to be well powered before the Ethernet has started, because if the Ethernet starts before the clock coming from the ESP32, then the Ethernet will hang. Usually that is controlled by the Ethernet power pin (e.g. keep the Ethernet in reset via GPIO12 and then after some moments, say 1 second, release it and initialize it). But maybe this was not properly done in 1.0.6.

The setup looks alright. Looks like only the Ethernet hangs not the whole board. Orange and black relays are similar, but we will test in similar terms as you.

Can you tell me about the bulbs that you used? Type, brand, wattage?

Can you test with other type or wattage of of bulbs?

Hi.
I assume you get that ethernet error, because when you select PSRAM,
also the pin assignments from the ETH controller are set for Wrover (or did
you define them in the sketch/code?).
For me the problem is that starting with POE power simply is unreliable. Sometimes it works, but also sometimes it doesn't. Does not seem to be SW related.
Strangly enough when I start with USB power (and a regular ethernet cable), it works 100% of the time.
And... when it does not start with POE power, when I press the reset button, the board always does start after that buttonpress. Looks more to me a POE power timing Reset_ESP32 issue?
Thx.
Joop

Switching the relays, without load is not a problem at all:
https://streamable.com/5vh9u0

But when I try to switch the relays with a load, I get only a few tries:
https://streamable.com/w4ba0t

I have attached a USB connector to see the logs in putty and when I try to switch with a load, this is what I get:

Hi,

thank you for the reply, if we focus on issue 1:
I tested pretty straightforward with two lamps.
The setup:

The lamp on PIN32 Relay is ON:

The lamp on PIN33 is ON:

Both lamps are ON:


I followed your links and the relays on your board are orange, while mine are black, could this cause the problems?

I should be nowhere near the power usage I saw in you video with the drill.

Last post by LubOlimex - May 05, 2025, 04:45:27 PM

What I can say for sure is I get errors with Ethernet when:

- I use latest ESP32 release;
- I select ESP32-POE from the board selector;
- I disable PSRAM from the board options.

This leads to Ethernet problems with ESP32-POE2.

Indeed, One of the things I tried as well, going to the latest ESP32 PlatformManager. When I do, I run into multiple issues of SD MMC not working, to Firebase giving compiler errors but can switch off oblviously) to some other libraries I need to rewrite (OTA and FirebaseStorage). Also, the new Firebase libraries have their stability issues as well. Anyway, I may need to go ahead and overcome/bypass all this to do a try with the latest platform manager. What extra's are implemented in the download with latest IDE platform manager (I see in boards.txt)  ? Does extra stability code get added?

" esp32-poe.menu.PSRAM.enabled.build.defines=-DBOARD_HAS_PSRAM -mfix-esp32-psram-cache-issue -mfix-esp32-psram-cache-strategy=memw "

Thanks.
