Topic: new firmware 1.3.5 for GW1200

[Gyvate]

GW1200 V1.3.5 release：
- Supports IoT device WFC02.
- Supports LDS01 data filter level algorithm.
- Supports relative air pressure algorithm based on altitude.
- Supports VPD webpage display, data upload, and IoT smart control.

Just saw this as available for my GW1200. Any known update issues or cautious before I update?

[Dirk27]

Everything fine here with this update.
You only have to control your altitude setting, item "Altitude for REL".

oops - too late 
1.3.5 has been occasionally reported for attracting bigger birds to the outdoor sensors ....

Repelling would be better

OK ... so I have v1.3.4  and the other day the UI was telling me I could update to 1.3.5,  but now,  I go to the Device Settings page when on my local network and I click check firmware and it says the attempt Failed.  I am NOT getting an option to update to v1.3.5

Having the same problem as well. They might have withdrawn the update or it is because of the tariffs. 

[MrM1]

I doubt Tariffs,  but using the Ecowitt app on my phone and the same local area network as the device, the Update button reports that v1.3.4 is not indeed the latest version.  So they must have with drawn v1.3.5 or some reason.

[OldAlaskaGuy]

After the Ecowitt outage today I rechecked for the 1.3.5 update. Still not available.

will check with Ecowitt what the 1.3.5 status and the WSV+ situation is

1.3.5 has been withdrawn due to potential issues

Thank you

New firmware released v1.3.6 for GW1200, installed without issues. I guess I set the ABS offset and the elevation and the REL is calculated by the elevation value. Correct?

[Dirk27]

The REL is calculated using the altitude, menu item "Altitude for REL", since V1.3.5.

an ABS offset is usually not needed - why would you want to correct the real-existing local air pressure ?
Unless you have a reference barometer which shows a deviation between itself and the console (or WN32P) readings, I'd leave it as it is.

I have always used one of the calibration calculation methods posted here on these forums using local airport METAR values. If I am within ± .2hPa/24 hours should that be close enough? I am not using a console, but viewing on web based applications. The biggest issue is getting all real time values from all these web base applications, some are updated at different intervals.

[Gyvate]

maybe you read chapter 8 about barometer in the WiKi.
A local airport may not have the local air pressure at your barometer location and height (altitude).
And your GW1200 has an inbuilt barometer ! The barometric chips used in the Ecowitt consoles (the GW1200 is also a console functionally --> WiKi: consoles) provide pretty ood readings +/- 0.5 hPa (even though the chip speciications say +/ 5 hPa).
Calibration is best done in hPa. When you prefer to see mmHg or inHg, switch to these units after calibration.
Your GW1200 is your best source of local air pressure, no web application or local airport (unless really next door and the airfield at the same altitude as your barometer) can be so correct.
also for proper terms: altitude, height, elevation see WiKi).

[OldAlaskaGuy]

Thank you for your help, It is much appreciated. I use the SLP provided by the airport as a reference. The airport elevation is 99 ft and my station elevation is 141 ft. and 10 miles away. I do the setup in hPa/mb. You have, in the past, have given excellent advice. I will take your suggestion and set the ABS offset to 0 and watch the pressure.
This is the calibration worksheet I have been using. Barometer Calibration Adjustment Helper It uses SLP in the calculations.

I see this morning there is now a v1.3.6 available to me for the GW1200.  Odd,  I was never able to get 1.3.5.

1.3.5 was withdrawn due to some issues - it's replaced by 1.3.6
