Using ethernet instead of Wi-Fi (wESP32) #92

Open Eagleman7 opened 1 year ago

Eagleman7 commented 1 year ago

Thanks for building and maintaining this great piece of software!

My wESP32 has become quite unreliable for some reason. The latency for Wi-Fi is all over the place making it impossible to send commands to my Switchbot devices. This is probally unrelated to your code.

I was wondering if it is possible to use the PoE ethernet port on my wESP32 instead of using Wi-Fi for network connectivity. Let me know if I can help you out with testing this!

devWaves commented 1 year ago

do u specifically need the POE? if no they have esp32s with external antenna also that are cheap

as for the support of ethernet, you would want to check out this issue ticket reported in the EspMQTTClient library that I use...

https://github.com/plapointe6/EspMQTTClient/issues/97

are you noticing if the esp32 is rebooting at all? you would see a status "boot" message on the main MQTT topic. Just wondering if you're issue is more related to POE power supply issue

Eagleman7 commented 1 year ago

Sorry for the late reply, the device almost got fried because I left the window open and the wESP32 got soaked in water. Luckily it still works after drying for a day.

I thought POE would be helpful because then I can't have any issues with wireless connectivity and I don't need to run an external power supply near a wall outlet.

I cannot see anything boot related in MQTT: image

Is the code able to connect through ethernet at all, currently it seems that it is just getting power through the ethernet cable but I do not see a DHCP lease.

devWaves commented 1 year ago

no the code doesn't work with an ethernet cable. The library (espmqttclient) doesn't support non-wifi yet

Flachzange commented 10 months ago

Hi all, I would like to resurrect the topic. I want to use my Olimex ESP32 POE and its Ethernet connection. I am actually super new to this.

no the code doesn't work with an ethernet cable. The library (espmqttclient) doesn't support non-wifi yet

Is that still the case? At least there is a constructor for MQTT only (without wifi) I actually wanted to test this, but my bigger issue is actually that the sketch is getting too big in the moment I include the ETH.h and initiate the Ethernet connection.

@devWaves, is that realistic? Is the standard sketch already at its limits? Do you have a recommendation what I can safely remove, i.e. might be optional?
