Bridgetech probe MIB support

Hi, would it be possible to add support for these devices please? It does not seem to respond to general SNMP oid queries...  basically I wanted to be able to read out IAT/MLR/nosignal values for multicast streams  for the last minute for each available stream, like this and then create  alarm above certain threshold for this:

$mib = 'btech_probe1.mib';
$config['mibs'][$mib]['enable'] = 1;
$config['mibs'][$mib]['mib_dir'] = 'bridgetech';
$config['mibs'][$mib]['identity_num'] = '.1.3.6.1.4.1.24562';
$config['mibs'][$mib]['sensor'][] = array('oid' => 'mlrerrEntry',
                                         'class' => 'runtime',
                                         'oid_extra'  => [ 'channelName', 'channelIpa'],
                                         'descr'      => 'MLR: %channelName% (%channelIpa%)',
                                         'oid_num' => '.1.3.6.1.4.1.24562.520.1.7');
