I will get the Belchertown after I can figure out how to map some of the additional data elements from the Tempest and hub. I ran with raw packets for about 10 minutes and notice that there is defiantly data that is not mapped and the default widgets have no values and could be mapped. For example sensor status:

I see the raw UDP packets have data to account for battery, RSSI and some other things. Trying to review the documentation on the field mappings with this UDP packet and update the sensor_map:

{'serial_number': 'ST-00006682', 'type': 'device_status', 'hub_sn': 'HB-00017489', 'timestamp': 1640030190, 'uptime': 11270176, 'voltage': 2.778, 'firmware_revision': 156, 'rssi': -68, 'hub_rssi': -59, 'sensor_status': 0, 'debug': 0}

[[sensor_map]]
    outTemp = air_temperature.ST-00006682.obs_st
    outHumidity = relative_humidity.ST-00006682.obs_st
    pressure =  station_pressure.ST-00006682.obs_st
    lightning_strikes =  lightning_strike_count.ST-00006682.obs_st
    # avg_distance =  lightning_strike_avg_distance.ST-00006682.obs_st
    outTempBatteryStatus =  battery.ST-00006682.obs_st
    windSpeed = wind_speed.ST-00006682.rapid_wind
    windDir = wind_direction.ST-00006682.rapid_wind
    windGust = wind_gust.ST-00006682.obs_st
    # lux = illuminance.ST-00006682.obs_st
    UV = uv.ST-00006682.obs_st
    rain = rain_accumulated.ST-00006682.obs_st
    windBatteryStatus = battery.ST-00006682.obs_st
    radiation = solar_radiation.ST-00006682.obs_st
    # lightningYYY = distance.ST-00006682.evt_strike
    # lightningZZZ = energy.ST-00006682.evt_strike

The example map on the driver’s website applies, with the exception that there are two battery mappings where there’s only one needed for the Tempest. My guess is it’s due to its original Air+Sky lineage where both had batteries.

You can of course map the RSSI etc. to anything you want in unused fields in the db.

Consult the weewx-user group for how to get battery status to show voltages rather than ok/low (from its VP2 lineage) and the like. It’s pretty easy. If you run the Seasons skin the new 4.6 of weewx currently in beta will make this even easier to set up.

There are lots of Tempest threads in weewx-user with what folks have solved so far. Poke around over there and use the search functionality…

Got Belchertown up and running over the last week, did it piece by piece but everything is working MQTT, Weather Forecasts etc. Just a few minor tweaks remain but it’s a great skin:

Good work there. I’m in Oak Lawn and just got my old 3b+ Pi up with weewx, seasons & belchertown.
not quite as far as you. but seeing it done, and recently gives me hope i can figure it all out. (i’m not a programmer but i have awesome ‘google’ skills) - thanks for sharing your screenshot Great job.

My trusty Davis Vantage Pro 2 finally gave up the ghost and died. I have no bought a Weatherflow Tempest. I want to continue sending data to my website. So far I have managed to do that using a RPi4 with WeeWx and the Belchertown WeeWx skin. Being none to literate in HTML, Python, JS etc my mind is getting overloaded with “new stuff”. My issue at the moment is getting Solar and UV data to display on the Web Page. If I look at the belchertownweather.com site to the left of the Radar I see there are values for UV Index and Solar. On my page those two entries are missing. Do Ineed to make changes to the Weewx.conf file to get them to appear, if so what changes are needed. If the changes need to be made else where, can you point me in the right direction please? In a similar vein is it possible to display lightning data (time, distance) on the main page?

The weewx-user google group is where you should be asking those things…

To get UV + solar into your db you need to add lines to the sensor_map for your driver, but the example tempest sensor map already defines them so it is likely your db is saving those items already.

To add items to the left of the radar image you want to edit the “station_observations” element to add which ones you want and in which order. Look in the general options page for the info.

Whenever you edit weewx.conf you need to reset weewx so your changes take effect.

My apologies for using the wrong group, I’ll switch over to that one. Thanks for the response, I am just rebuilding the Linux box then I’ll give it a whirl.
