New OS - Data shows in Discovery but not in poller

@laf I was able to copy and strip down the includes/discovery/sensors/pre-cache/avtech.inc.php

I have created:
includes/discovery/sensors/pre-cache/esphome.inc.php

$data = trim(snmp_walk($device, '.1.3.9999', '-OQn'));
foreach (explode(PHP_EOL, $data) as $line) {
    [$oid, $value] = explode(' =', $line);
    $value = trim($value);
    $pre_cache[$oid] = [[$oid => $value]];
}

unset($data);

With the addition of the above file, polling is working as expected using the following yaml:
includes/definitions/discovery/esphome.yaml

modules:
    sensors:
        dbm:
            data:
                -
                    oid: .1.3.9999.4.1.0
                    descr: 'RSSI of {{ $.1.3.9999.4.3.0 }} connected to {{ $.1.3.9999.4.2.0 }} with IP: {{ $.1.3.9999.4.4.0 }}'
                    group: 'WiFi'
                    num_oid: .1.3.9999.4.1.0
        state:
            data:
                -
                    oid: .1.3.9999.2.1.0
                    descr: 'Chip Type'
                    num_oid: .1.3.9999.2.1.0
                    group: 'Chip'
                    #state_name: 'Chip Type'
                    states:
                        - { value: 32, generic: 0, graph: 0, descr: 'ESP32' }
                        - { value: 8266, generic: 0, graph: 0, descr: 'ESP8266' }
        frequency:
            data:
                -
                    oid: .1.3.9999.2.2.0
                    descr: 'Chip Frequency'
                    num_oid: .1.3.9999.2.2.0
                    group: 'Chip'
                    multiplier: 1000000

That said, the php seems to just pre-cache the values. Unlike the avtech.inc.php file, no virtual tables are constructed.

Other OS’s do pre-cache in the yaml like netgear.yaml. Here is the pre-cache section:

    sensors:
        pre-cache:
            data:
                -
                    oid:
                        - boxServicesNormalTempRangeMin
                        - boxServicesNormalTempRangeMax

I tried creating the equivalent pre-cache section in the esphome.yaml using both just the base OID and specific OID’s used in the sensors. Neither was successful.
