Add "time" of transmission in mqtt

[kobold81]

Current Situation

the current mqtt message lacks a "time" field. with rtl_sdr what field gets delivered.

{"model":"Bresser-7in1","id":1272,"temperature_C":16.6,"humidity":89,"wind_max_m_s":0,"wind_avg_m_s":0,"wind_dir_deg":286,"rain_mm":1026.4,"light_klx":9.308,"light_lux":9308,"uv":0.6,"battery_ok":1,"mic":"CRC","protocol":"Bresser Weather Center 7-in-1","rssi":-79,"duration":40000}

Proposed Change

please add the "time" field to the mqtt mesage

Additional Context

No response

[NorthernMan54]

Adding time to the returned message should be a function of the framework managing the response, as time requires significantly more complexity.

I agree with you but I think I was unclear in my request:

The bresser weather station sends with each message the current time as received by the on board DCF receiver. the RTL-SDR provides that information a a separate field and also puts that to mqtt like the temperature and other sensors values.

Because I switched from raspberry to esp32 wih openmqtt gateway which uses your modules, I noticed that the time field was suddenly missing :-)

is there a chance that you could also send this info?

[NorthernMan54]

The device decoders are a direct copy from the rtl_433 code base, without changes. Take a look at the source to see what the issue is

my apologies, seems that this issue will be fixed as you said on the platform level. In the current 1.7 version it is mentioned in the release notes:

[SYS] Add timestamp for messages by @dkneisz in 1technophile/OpenMQTTGateway#1677

and the feature is to be switched on by editing the User_config.h:
