please add support for ASCO Transfer Switch

hi, can someone please look at this issue.  it has been languishing and i would appreciate some effort on it.

mike, i upgraded to 21.12.11834 and i am seeing some issues.  i deleted and then re-added the transfer switch and it is no longer displaying the manufacture icon, it lists it as a generic device.  also....(i know this will sound weird), but the device seems hang after sever polling attempts.  I know this might seem like "not your problem" but i am quite certain that this was not happening before the new version.  i had the transfer switch in observium for at least a week and it did not hang once, now, i cannot get it to stay up more than an hour.

These sensors was added in r11816.

Mike, i am sorry, but that is not true...first, t

ASCO-QEM-72EE2::normal_voltage_phase_AB.0 = INTEGER: 245
ASCO-QEM-72EE2::normal_voltage_phase_BC.0 = INTEGER: 250
ASCO-QEM-72EE2::normal_voltage_phase_CA.0 = INTEGER: 245

these are not fixed, that are measured and fluxuate by the second.

these also fluxuate when main power has been lost and emergency power is up...that is probably the most important of, knowing when you have lost main power

ASCO-QEM-72EE2::main_on_normal.0 = INTEGER: 1
ASCO-QEM-72EE2::main_on_emergency.0 = INTEGER: 0
ASCO-QEM-72EE2::auxiliary_on_normal.0 = INTEGER: 0
ASCO-QEM-72EE2::auxiliary_on_emergency.0 = INTEGER: 0
ASCO-QEM-72EE2::normal_source_available.0 = INTEGER: 1
ASCO-QEM-72EE2::emergency_source_available.0 = INTEGER: 0

Anyway, I just added discovery some sensors in r11816.
But I think this values will never changed.

There no real sensors, but normal/nominal values (configured on device).
All of these values ​​will never change for any time.

mike, i scanned through the walk, these are the sensors i think would be important

ASCO-QEM-72EE2::phase_shift_between_normal_and_emergency.0 = INTEGER: 18
ASCO-QEM-72EE2::normal_frequency.0 = INTEGER: 60
ASCO-QEM-72EE2::emergency_frequency.0 = INTEGER: 0
ASCO-QEM-72EE2::main_on_normal.0 = INTEGER: 1
ASCO-QEM-72EE2::main_on_emergency.0 = INTEGER: 0
ASCO-QEM-72EE2::auxiliary_on_normal.0 = INTEGER: 0
ASCO-QEM-72EE2::auxiliary_on_emergency.0 = INTEGER: 0
ASCO-QEM-72EE2::normal_source_available.0 = INTEGER: 1
ASCO-QEM-72EE2::emergency_source_available.0 = INTEGER: 0
ASCO-QEM-72EE2::normal_voltage_phase_AB.0 = INTEGER: 245
ASCO-QEM-72EE2::normal_voltage_phase_BC.0 = INTEGER: 250
ASCO-QEM-72EE2::normal_voltage_phase_CA.0 = INTEGER: 245
ASCO-QEM-72EE2::normal_voltage_unbalance.0 = INTEGER: 0
ASCO-QEM-72EE2::emergency_voltage_phase_CA.0 = INTEGER: 0
ASCO-QEM-72EE2::controller_software_version.0 = STRING: 894063-035
ASCO-QEM-72EE2::controller_software_date.0 = STRING: 09/27/18
ASCO-QEM-72EE2::engine_running.0 = INTEGER: 0
ASCO-QEM-72EE2::controller_state.0 = INTEGER: 0
ASCO-QEM-72EE2::controller_status_state_data.0 = INTEGER: 0
ASCO-QEM-72EE2::current_sensing.0 = INTEGER: 0
ASCO-QEM-72EE2::phase_A_current.0 = INTEGER: 0
ASCO-QEM-72EE2::phase_B_current.0 = INTEGER: 0
ASCO-QEM-72EE2::phase_C_current.0 = INTEGER: 0
ASCO-QEM-72EE2::controller_serial_number.0 = STRING: BER212315334
ASCO-QEM-72EE2::total_number_of_TS_transfers.0 = INTEGER: 3
ASCO-QEM-72EE2::total_number_of_TS_transfers_due_to_source_failures.0 = INTEGER: 1
ASCO-QEM-72EE2::boot_loader_version.0 = STRING: 894053-003
ASCO-QEM-72EE2::normal_breaker_tripped.0 = INTEGER: 0
ASCO-QEM-72EE2::emergency_breaker_tripped.0 = INTEGER: 0

Mike, i'm not sure i understand...there are values in the walk... for example

ASCO-QEM-72EE2::normal_voltage_phase_AB.0 = INTEGER: 245
ASCO-QEM-72EE2::normal_voltage_phase_BC.0 = INTEGER: 250
ASCO-QEM-72EE2::normal_voltage_phase_CA.0 = INTEGER: 245

shows the voltage on the 3 phases...this is important info to know. also

ASCO-QEM-72EE2::main_on_normal.0 = INTEGER: 1
ASCO-QEM-72EE2::main_on_emergency.0 = INTEGER: 0
ASCO-QEM-72EE2::auxiliary_on_normal.0 = INTEGER: 0
ASCO-QEM-72EE2::auxiliary_on_emergency.0 = INTEGER: 0
ASCO-QEM-72EE2::normal_source_available.0 = INTEGER: 1

tells us whether we are on normal or emergency power...also important...

This is mostly derp MIB and SNMP data which I have seen.

It just doesn't make sense to add any sensor, because all values 0 (zero) or unreal.
See translated snmpwalk which I attached ( asco.walk ).

Anyway, I added poll approximate uptime and software version (if this values real) in r11814.

snmpwalk added
