tHAT + GSM overlay
For Lan Controller HW 3.7, 3.8
Version of the tHAT overlay extended with a GSM module, currently available in the IDC10 version with IDC10 connectors for connecting the relay boards.
The tHAT module offers additional 4 outputs in the open collector standard, driven by PWM outputs, for controlling relays. The board also has an RS485 converter for Modbus bus support. There are also outputs OUT1-OUT4 and supply voltage, analog inputs INPA5 and INPA6, and 3.3 V voltage for powering sensors.
The GSM overlay enables LC
- Controlling outputs via SMS (on/off/reset).
- Sending SMS as an action in Events.
- Sending HTTP requests (e.g. cyclical sending of readings) over the mobile network.
- Sending MQTT data (e.g. sensor readings) over the mobile network (feature available soon).
The GSM module uses a serial port, therefore it is no longer available for connecting other devices or sensors.
