Firmware 1.2.0

Main changes

• Support for both Blynk (legacy) and OpenThingsCloud (OTC) connections. Please refer to user manual and support article about how to create and use cloud tokens. In particular, OTC allows full remote access of the built-in web interface.
• Added MQTT enable option to easily enable/disable MQTT without changing the other parameters.

Please note that due to the size of this firmware, the flash memory layout has changed. Upgrading from any previous version of OpenGarage firmware to this version (1.2.0) will trigger a factory reset so it goes back to factory reset condition. Also, this firmware only works on ESP8266 chips with 4MB flash (OpenGarage 1.3 and above, including 2.x all have 4MB flash).
