Sensors v2.1.0

• Added ability to set addresses in settings instead of using headers. This decreases components to be soldered and makes it easier to use Unos, Pro Minis or other full size Arduinos.
• Changed topology image to reflect new PCB shape.

Sensors v2.0.0

• Changed the way how automatic transmit power control works: now it targets a certain user settable RSSI instead of lowering power until transmits fail. See node settings for more info.
• Changed acknowledgements from gateway to nodes. This enables the changed power control method and gives more options in the future.
• Updated example scripts save_modbus_to_db.py and read_modbus.py to reflect changes made in underlying libraries and to make them easier to use.
• Added a script check_alarms.py as an example on how to send email alerts under different conditions.

Note: Due to the changes, version 2 gateway is no longer compatible with nodes running lower versions. Messages will be delivered but because nodes expect different kind of acknowledgements, they will consider messages lost. This triggers retransmits, full transmit power and more battery usage.

Sensors v1.1.3

• Fixed number of last seen nodes zeroing after 2^16 minutes. #12

Sensors v1.1.2

• Fixed 23K256 SRAM handler transactions. #8
• Fixed initial transmit power of battery and pulse type nodes.
• Fixed RFM95W transmit powers to address changes made in the RadioHead library.

Sensors v1.1.1

• Fix and refine NTC sensor reading and calculations in NTCSensor.
• Fixed a possible memory allocation error in SensorsSRAMHandler.
• Update GPL to version 3 and bump copyright years to 2020.

Sensors v1.1.0

• Pulse 2 in gateways can be configured as an external interrupt (active low open drain) which informs upstream device of a new message. See gateway settings for more information.
• Battery and pulse nodes have a new important mode set by the jumper J1. Setting this mode will trigger gateway to set external interrupt when an important node sends new messages.
• ID of the last received node added to gateway Modbus registers.
• Changed some button and header functions. See readme.

Sensors v1.0.2

• Fixed overflow bug in gateway uptime calculation after 45 days.
• Added image of a wired Si7021 breakout board.

Sensors v1.0.1

• Fixed a bug in NTCSensor library where enable pin was controlled even though it was not in actual use, possibly interfering with serial communication.

Sensors v1.0.0

This is the first public release with all the necessary features, tested and ready to be put into service.
