My Arduino Nano must now talk to an nRF24L01+ in addition to the OLED and si7021 temperature and humidity sensor.

I'm gonna call my mini, Andy the Arduino
Hi Julian, I'm a fan. look into simple whirlybird ventilation. might work, but need to know if it handles snow. Molds is very dangerous fix it quick.
Great seeing you work. Much better than watching demo videos.
Got mine up and running today and broadcasting temp & humidity across the flat.
What I did though was to put the radio.write in an if statement comparing the current readings to the previous ones so it only broadcasts if something changes.
Have you considered using a rf-nano? NRF and a nano in one unit 😊
I get peeved every time I see a simple solution ( using a couple of libraries and hey presto, a few line of code and it's working ) knowing that it's all done under the Arduino framework. No true debug facility, slow IO access, and generally not something to use in a professional environment.
I've had need to 'steal' some libraries… hack them back into C code and use with AVR Studio to get working in a proper debuggable IDE.
Am I missing a trick here?
You do the long way around on the SI7021 for humidity and temp normally all you have to do is a Get humidity call and it will get both and much faster . Just a little idea for ya . Cheers
Use a esp32 has wifi and deep sleep
Glad I saw this one because I didn't quite know how the two boards plugged together and would have blown them up the way I did it. I'd like a "you've got mail" sensor for my mailbox about 50 to 100 ft away. The receiver combined with that tx and some sort of sensor , maybe the radar, or something, and I've got it.
It's more the condensation that causes the problems, a 4 degree drop in temperature will take 80% to 100% relative humidity.
Mr Julian – thank you for many, many hours of tuition and entertainment over the years. You will never know how much you taught me! Your videos and tone are so informative and soothing. Countless hours spent watching your posts intensely, and repeating whilst falling asleep to your smooth and genuine delivery. Again, just a big thanks for all of your work.
