Economical and Automated Home Heating System

Device should be down only if the internet is down. If sensor causing problems script continuously reset ESP8266 board until a sensor is fixed.  The script should handle problematic sensor and continue to update other sensors. Picture show downtime before handling problems. Each time when sensor fali Blynk update terminal with name of fault sensor and time of fail.

In rare occasion I want to  block home heating. Thermostat is programed to turn on heating every day at specific time and it operates independently. This circuit can shut down home heating in every moment regardless of thermostat status. 

I'm loging data with MicroPython REPL prompt.

Writed python script to figure out problem, it seems that watchdog timer reset ESP board.  Trying to increase wdt timeot. Link

from machine import WDT
wdt = WDT(timeout=2000)  # enable it with a timeout of 2s
wdt.feed()

Something is wrong :) ESP should reset after 5 update exception.  I will log serial port  REPL to figure out what happened.

I am currently testing the stability of the system . Everything is connected only to monitor the operation of the system.

I have not yet decoded the Blynk RTC time format. I am working on that instead of this it displays the exact date and time when the measurements were performed.

Update: 

Blik server using unix time stamp and micropyhon have function utime.localtime() to decode stamp.

More info at time related functions.
