One cheap component stops my "Home Alone" device
►JLCPCB $2 for 5 pieces https://www.jlcpcb.com/cem
Just fix it, right? Well, it was 800 miles away in a different country. Dang!
This unit (there are two) monitors movement in my mum's apartment so we know she's OK. Lack of movement over a period of time (90 minutes) sends us an email. All activity is uploaded to Thingspeak so we can see the results on a phone at any time.
The project used the Wemos D1 Mini ESP8266 stackable modules. These are small, uniformly-sized modules that just push-fit together to make connections very easy indeed.

► Main ESP8266 module, just £3 - £4
(See https://www.banggood.com/custlink/vmG...)
► Some other modules you can get for the system:
Dual Socket Base, Micro SD Card Reader/Writer, Relay Module
(See https://www.banggood.com/custlink/3Gv...)
► I also mention the use of an external aerial
Makes a huge difference to performance on both hardware platforms I mention.
