Thanks a lot again, I have now it working, but I have some issues that I want to ask you before digging on source code, because maybe is more easy to ask:

- I can't send messages to the OLED screen. The program is compiled and send it to LilyGo with the ENABLE_SSD1306 defined. I am not still using OpenHAB for this (all itrms are working ok on OH), because I like to test before. I am using MQTT Explorer so I can see all messages on the MQTT Mosquito server. I have tried sending with topic home/esp_gw/sb/node30/dev72 and topic home/esp_gw/nb/node30/dev72, but none of them prints anything on screen apart from original message. I have also tried messages with "1:xxx" and "1,xxx" (as you mention "colon" in some explanation). On MQTT I see a topic send by device with topic "home/esp_gw/nb/node30/dev72" that always have "text received", if I send something to this topic, change for some seconds, but again turns to "text received", nothing apears on screen.  

- On the other hand, if I point my browser to the device IP, I am able to see the camera, but I can't see it on sitemap directly with Image tag. I have other IP cameras that can see without any problem, and I am also able to see it if I put his IP on your 4 cameras sample html. But not directly on OpenHAB Image tag. Very extrange. I am also surprised, because the image is not really a "still image", maybe the problem is that is some mpeg stream? It works for you with Image tag on sitemap?

In any case, thanks very much, I can dig on the Esp32 code to resolve the issues, but probably asking first is better.

rubenkona, I'm glad you're making progress on using the camera board. It's been a while since I looked at the source code for the camera board so at present, your eyes may see more than mine. Let us know if you find ways to improve.

papa: Yes, it NOW, USUALLY works for me with IMAGE tag on a sitemap (or HABPanel). From what I remember, it did NOT work at first. I did things like this & eventually it mostly worked: Stopping & restarting openHAB, refreshing the browser or app holding the sitemap/HABPanel, stopping & restarting the camera board. As I mention in the thread above, the image/stream might only be accessible on one computer. However, lately, I've had some success accessing the image/stream (without refreshing the browser or restarting the camera board.

Regarding displaying messages on the SSD: I believe the same refreshing & restarting mentioned just above might have helped with this issue also.

One more thing that might help with these two issues: clearing the openHAB cache. See this post. (Though a caution: clearing the cache sometimes seems to introduce other issues.)

I have many features in my openHAB setup. My experience is that the more we set up in openHAB, the more resistant it becomes to adding new things or making other changes. Thus the need for refreshing/restarting/etc. This might also apply to your openHAB setup.
