write source or help trouble shoot using debugging tools our existing code.

C (Arduino IDE) but prefer to use Atmel Studio

Using ATmega328 or ATMega168P QFP CPU

Monitor 5 I/O pins - to determine if a switch contact is open or closed

Closed is Good, open is alarm condition

Also use A/D to drive an LM84T temperature sensor and measure once per minute

Alarm condition if temperature is over 75C

once per 5 minutes - use serial lines to operate and send a message using HopeRF RFM95 LORA radio module. (this is a 'status ok' message)

We have library for this radio module

When alarm conditions occur (contact open or temperature >75C) alarm message sent.

Message payload is 6bits - we have this defined.

Device sends messages only

1650mAH battery - target 5 years life

We have this all working but there is a bug causing CPU hand and battery drain.

considering fresh start as back up while we continue to troubleshoot the code we have.

Power source 3V non rechargeable lithium battery or Thionyl Chloride
