I don’t know the Tago Integration, but downlinks scheduled using the downlink_url from an uplink’s JSON message in the HTTP Integration, or using the MQTT Data API, do show as scheduled in the application/device’s Data page in TTN Console. So, if Tago schedules a downlink I’d expect to see it?
@shuvro, as TTN Console is not always reliable, you could subscribe to the MQTT device events, to see if a third party is scheduling a downlink, and to see when TTN delegates it to a gateway to be transmitted after an uplink.
If you’re in Australia and using Meshed, then see also Downlink URL 502 error API + Tago + Meshed.
