Power/temperature monitoring

Hopefully monitoring the status of a network is on-topic.

I'm looking for temperature and power monitoring unit to install in some
remote BWA cabinets.  We had two incidents where we lost power in a town and
we weren't aware of it until the backup batter drained to empty, and another
situation where the cabinet became too cold.  Because these cabinets are
less than 19" wide and just 3-5" deep, I need something quite small.  I did
find one product but it requires four components (unit with built-in
temperature sensor, adapter, and AC power sensor, plus power supply)

Perhaps there's someone on this list who has gone down this road and can
point me to a good product.

Required:
- temperature sensor
- 110 VAC power monitoring (on/off, not necessarily current)
- Ethernet interface (at least SNMP, Web GUI and 

Optional:
- fed via 12 VDC power
- 12 VDC power monitoring (current)
- humidity sensor
