When you get your own issues sorted out, I would be very interested to know if you can confirm whether or not your D1 boards successfully wake from deep sleep with the RTC alarm. It is widely acknowledged on a number of forums, github issues, etc. that various ESP8266 systems, including bare ESP-12 ...

Thanks for confirming my hunch that I probably just need the opposing transistor type. I suppose I could string two together as you suggested, although I admit that seems unnecessarily convoluted. Thanks again.

I agree, and I'm aware of the behavior in which the board would not fully reset until after the sensor returns to its initial state. For some reason I'm not getting any reset behavior by sending the signal straight into reset regardless of whether the sensor settles down a moment later. I don't get ...

I would have posted this in the ESP8266 forum, but it's really more of an electronics question, and probably a really basic one at that, given that I'm a software person with minimal electronics wherewithal. The ESP8266 and its support boards (such as the ESP-01S) can go into deep sleep and then awa...

Unrelatedly, I see you are using a D1 mini and you are using deep sleep. Does your D1 mini wake properly with a timer alarm (not a pushbutton or sensor interrupt)? If so, what D1 mini version is it and where did you get it? Thanks.

I'm trying to get a sense of how pervasive the D1 mini deep sleep error is, in which the D1 mini doesn't properly reset when waking with an alarm from deep sleep (described at https://github.com/esp8266/Arduino/issues/6007). How many people here have used MicroPython on a Wemos D1 of any model. Whic...

My apologies. Where I wrote GPIO0 above, I meant D0 on the D1 mini, which is GPIO16. Ugh. The pin aliases get confusing. I've edited my original post to correct the mistake. Moving on... Are you sure about hard-wiring GPIO16 to RESET? There are at least two levels of abstraction from the 8266 here. ...

I have two D1 minis, obviously running MicroPython, which exhibit a widely experienced problem in which they don't properly wake from deep sleep. I am forced to physically press the reset switch twice to recover a REPL (curiously, if I tie D0/GPIO16 to RESET, then a single push to RESET does the tri...

Thanks. I expected as much, but I just wanted to confirm it.

Okay. I see that in the REPL now: >>> PYB: soft reboot MicroPython v1.10-8-g8b7039d7d on 2019-01-26; ESP module with ESP8266 Type "help()" for more information. >>> import machine >>> rtc = machine.RTC() >>> rtc.[TAB] __class__ ALARM0 alarm alarm_left datetime irq memory >>> rtc. It's worth noting t...
