ESP8266 Setup

Prepare firmware:

• use my version esp_firmware/
• use https://nodemcu-build.com
• use hard (not so) way to build your own, manual here

Update firmware, manual and details is here.

RapidScada setup

TODO

Heartbeat

crontab entry

* * * * *       /opt/scada/regenerate_heartbeat.sh

Heartbeat logic: every minutes topic "heartbeat" pub new value generated randomly. Every session from ESP sensors network get new system value and re-publish it again and again to make sure that sensor is online and health state is OK.

TODO

• xor values temp and humi w/ current heartbeat values.
• RapidScada setup.
