Smart Room Heater

This code provide ability to control Load - Electric Radiator (ER) with Solid State Relay SSR. The application supports 2 modes of control:

Manual enable/disable the ER.
Automatic KEEP mode - will keep defined temperature in given range. The application has many security checks, in order to protect the work with the heater, while the user is sleeping or not at home. See Security section.

In Smart Heater project used:

2 * DS1822+ https://datasheets.maximintegrated.com/en/ds/DS1822.pdf 9-12bit -55-125
1 * nodeMCU
1 * Solid state Relay FOTEK SSR-25 DA
1 * 220v to 5v USB PS

On WiFi disconnect the load will be disabled(KEEP mode only)
Delay between disable to enable- default 60 seconds(KEEP mode only)
In case temperature value is anomalous the load will be disabled
Watch inside thermometer, the maximum inside temperature is MAX_POSSIBLE_TMP_INSIDE
Check Internet connectivity, if there is no ping to 8.8.8.8, load will be disabled
Add reconnect after X pings failures
Added _FLAG_FORCE_TMP_CHECK, When true will cause to immediately check, used also when thermometer wire were troubled
