Polling Temperature RB1100AH via Cacti SNMP or Scripting

We’ve been having -20F temps lately, and I installed a NEMA heater to help. We have a Mikrotik MIB on Cacti, but its only for wireless devices, and does not have have temperature graph. Is there a way to poll temp from the health via SNMP on graphs, or is there a feature on the new ROSv6 that allows you to email alerts when the temperature reaches certain thresholds or anything?

Thanks for any help.
