Yes, I found this command but hadn't realized that I only need to invoke it once. Now I do a gc.collect() after each time I have sent the webpage. Thanks. (I also do "del htmlstring" after it has been sent.)

My project is to build a general purpose relay controller based on input from various sensors. I want to see the current values of the sensors and be able to enter "on" and "off" values for the various sensors via web server. All of it runs on an esp32. And it now works -- reasonably well (with the ...

Sure is a big word for me but the board with which I have experienced most reliability problem has been powered with something that looks ok and with rated output 5V 2A so should be OK, no? Last night (24 hours ago) I did change the code to do the MQTTclient.connect and disconnect just before and af...

Thanks for input and guidance. What I'm trying to do is very simple: reading some temp and humidity sensors at various places and store these in a data base for plotting graphs/further analysis. I can definitely live with qos==0. If I miss a reading there is another one coming in a few minutes. But ...

Thanks again. Will have a look. A smaller step sounds right for me!

Thanks for the the reference. Actually I had started to look at Peter's mqtt library. My conclusion so far is that this library is where I should end up but it feels like a too big step for my coding skills right now. Also, will this library just help me cover up bad coding practices? Anyway good to...

I have a few esp32 boards with bme280 and ds1820 sensors scattered around a farm to monitor temperatures and humidity. Each esp32 has a oled screen showing the data picked up by the sensors on the local esp board. Currently the oled is on all the time and updated every 5 seconds. The esp32:s are con...

Of course you are right Robert. With the sh1106 library the (1.3inch) display works like a charm.
Thank you so much for the pointer! And thanks for a great source for all kinds of information.

Your finding about the 1.3 inch got me wondering and I suspect that is what I actually have... I'll check as soon as I get home.

Absolute newcomer + epsilon, but that epsilon gives me much joy.

Thanks for the quick reply (while I was trying to turn my picture in the right direction... ) I will try your this tonight and let you know. Also, I should correct my previous statement: It was by initation the display with different resolutions that I could get the narrow band to move around a. The...
