OK, I realise that everyone knows this except for me, but I am not experienced in compiling and understanding github repos.

ESP-12 RTC Accuracy
I am using the in-built RTC on the 8266 to deepsleep for an hour, but it seems to be highly inaccurate, although it's repeatability seems to be OK. secs = 3600 rtc = mc.RTC() rtc.irq(trigger=rtc.ALARM0, wake=mc.DEEPSLEEP) rtc.alarm(rtc.ALARM0, (secs*1000)) In sleeping for 1 hour, it wakes up on aver...

Re: Unable to use DHT on pins 4, 5 & 15
OK, just found the cause, there's no on-board pullup so you need to use the soft pullups:

Re: Esp32 port
@Roberthh - thanks for sharing your tools, I have tried the ftp server, and although I have files / folders on the device, the ftp server does not appear to list them.

Re: global variables across all modules
@deshipu - Thanks, that works very well.
I did not know that if you modified variables in a imported module, that it would retain those values when imported into another.
