Weatherflow’s support for local readings is one of the reasons why I got a Tempest in the first place - the idea that you need a fully working Internet connection to know the temperature in your own backyard just doesn’t make sense to me. Enhancing your own readings with input from Weatherflow’s bac…

Oh, sounds like you’re still talking about reading raw BLE from the hub. Yeah, i confirmed that the hub still sends data with the ubertooth. (Thanks for the tip about using nRF connect which gets the same info but I preferred to sniff using Linux so I didn’t have to wonder if it was my phone’s BT …

Gotcha. When I put my phone (iOS) in airplane mode with Bluetooth only enabled, I can see the hub data when pressing the small icon on the upper right of the screen, and the hub’s Bluetooth blue led turns on. The main dashboard page complains it can’t reach the server, which is expected, since it no…

I tried replicating that scenario. iOS app v5.01(609). Bluetooth On, Open app and connect. Hub light turns blue. Turn on Airplane mode. Data in dashboard freezes and no longer updates. If I try to click on the wind sensor, I get “no data at this zoom level”. I am testing by paying attention t…

I just tried again: when in airplane mode, data in dashboard still updates at regular interval, but I cannot see the graphs anymore, I get the same zoom level error you’re getting. So yes, unless you have some local setup that will read hub data over UDP or the Bluetooth interface to store it in a …

Thanks for taking the time to test with me. In your setup, What dashboard data element is updating for you? And how often?

[image] Bluetooth Operation only on my Boat Tempest Owners i agree, it looks like that is the case. When I turn off the internet in my router, it stops updating in the app. So its not only bluetooth that isn’t used, also the local wifi isn’t used by the app to communicate …

Hey. Is anyone able to share how they’ve decoded the BLE notifications? I’m getting hex characters like this: 18eb1998 08506600 000000 52eb1985 08506623 09000015 00000000 001300 1a53542d 30303133 ******** 00bc0014 ad7a0900 but I can’t seem to make sense of it. Thanks!

Do you mind sharing how to decode the BLE packets?

Here is a bit of code that decodes a BLE notification received from a Tempest hub. I have not touched this for a long time, format may have changed, so please take it with a grain of salt: // Parse a Weatherflow BLE packet, and send data to front-end if necessary var parseWeatherFlowBLE…

Thank you so much! That’s really helpful. I’m going to try to convert this code to run on an ESP32 using ESPhome and output to MQTT. This way the station can be completely offline. Did you have any luck decoding the lighting information or rain/hail?

Sunny confirmed my findings. Did you get different results?
