MQTT payload

[h_vestbo]

I want to show info from a MQTT server on my mirror.
Its a big payload on the topic, coming from a ttn sensor.
For a noob, whats the best way to pick out just some of the info from the payload?

Example of the payload from the topic:

{“end_device_ids”:{“device_id”:“eui-a84041d0f187ec73”,“application_ids”:{“application_id”:“roatoppen”},“dev_eui”:“A84041D0F187EC73”,“join_eui”:“A840410000000101”,“dev_addr”:“260B15F1”},“correlation_ids”:[“gs:uplink:01HQ56FZSCBY0SP7PAVYR6F9DC”],“received_at”:“2024-02-21T06:43:49.882988265Z”,“uplink_message”:{“session_key_id”:“AY3Hi2rqxf75puTSvmOKRQ==”,“f_port”:2,“f_cnt”:40,“frm_payload”:“DgsANQAADH//f/8=”,“decoded_payload”:{“ADC_CH0V”:0, “BatV”:3.595, “Digital_IStatus”:“L”, “Door_status”:“OPEN”, “EXTI_Trigger”:“FALSE”, “TempC1”:5.3, “TempC2”:3276.7, “TempC3”:3276.7, “Work_mode”:“3DS18B20”},“rx_metadata”:[{“gateway_ids”:{“gateway_id”:“eui-5030354148724750”,“eui”:“5030354148724750”},“time”:“2024-02-21T06:43:49.143920Z”,“timestamp”:962651492,“rssi”:-117,“channel_rssi”:-117,“snr”:-18.25,“location”:{“latitude”:59.610908127642695,“longitude”:5.824582718642445,“altitude”:20,“source”:“SOURCE_REGISTRY”},“uplink_token”:“CiIKIAoUZXVpLTUwMzAzNTQxNDg3MjQ3NTASCFAwNUFIckdQEOTKg8sDGgwIpbfWrgYQ87bMwgIgoJ2AlIKBCQ==”,“received_at”:“2024-02-21T06:43:49.651226007Z”}],“settings”:{“data_rate”:{“lora”:{“bandwidth”:125000, “spreading_factor”:12, “coding_rate”:“4/5”}}, “frequency”:“868100000”, “timestamp”:962651492, “time”:“2024-02-21T06:43:49.143920Z”},“received_at”:“2024-02-21T06:43:49.677482764Z”,“consumed_airtime”:“1.482752s”,“locations”:{“user”:{“latitude”:59.61374942705063,“longitude”:5.812596894821476,“source”:“SOURCE_REGISTRY”}},“version_ids”:{“brand_id”:“dragino”, “model_id”:“lsn50v2-d20”, “hardware_version”:“unknown_hw_version”, “firmware_version”:“1.1”, “band_id”:“EU_863_870”},“network_ids”:{“net_id”:“000013”,“ns_id”:“EC656E0000000181”,“tenant_id”:“ttn”,“cluster_id”:“eu1”,“cluster_address”:“eu1.cloud.thethings.network”}}}

The info I want to use is the TempC1 value

@h_vestbo Hi, my MMM-ValuesByNotification module is able to select single values in Json structures by JsonPath so does my MMM-MQTTbridge module.
You can receive the MQTT message with my MMM-MQTTbridge module, trigger a notification and display it with the MMM-ValuesByNotification module.
