We would like to poll the temperature of this Netgear WNR3500L v2 Router via SNMP. The attached image shows that DD-WRT reads it. An SNMP walk does not appear to bring up any temperature OIDs.

Can anyone help me as to what to do?
Many thanks

Not SNMP but you can save temp data to a network drive
Code:
#!/bin/sh

# log cpu temperature periodically

OUTFILE=/tmp/var/tmp/updatetemp.log

cat /proc/dmu/temperature >> $OUTFILE

exit 0

and run it with cron e.g every ten minutes.
Code:
*/10 * * * * root /opt/bin/updatetemp.sh
