Possible Firmware Stability Issue with version 1.4.2 and 1.4.4I waited a few weeks and decided to upgrade my WS-2000 to 1.4.4. I was still on 1.4.1. So I skipped 1.4.2. I found all kinds of stability problems with 1.4.4.
- awnet app would constantly show and not show the WS-2000 under device list. It appears for a few seconds and then disappears.
- awnet app in Device List when selecting WS-2000 will delay and show a pink circle spinning (hour glass)...times out sometimes...finally load WS-2000 configuration screen very delayed.
- WU upload frequency was not reliable with delays of over 1 minute at times. Hardly ever a 16 second upload.
- Ambientweather.net upload also was not reliable missing sometimes several minutes before an upload update.
I then felt that maybe the WiFi firmware may also need to be updated to keep up with the newest Revision Firmware. So I upgraded from 4.1.1 to 4.1.5 on the WiFi firmware. This was difficult to accomplish as it kept failing as the device was very unreliable as I think it kept internally rebooting or falling off the WiFi network (not sure which). After multiple attempts finally completed WiFi firmware upgrade to 4.1.5. Still same issues as before.
Then I decide to downgrade to Revision Firmware 1.4.2. But noticed the same behavior.
Then I decided to go down yet again to Revision Firmware 1.4.1. Ahhhh everything is fixed. WU uploads at 16 seconds, Ambientweather.net uploads at 1 minute, and awnet app never drops WS-2000 console from device list and loads up its configuration instantly.
I then tried to go back to 1.4.4 in case I got a bad flash or something. Nope didn't work. All these issues came back. So back down to 1.4.1 and all is fine again.
At this time I'm recommending staying with Revision Firmware 1.4.1. If you have a new PM2.5 then you'll need to live with these reliability issues to keep using the PM2.5 sensor. I've reported this to Ambient. Hopefully we see a new firmware soon.
UPDATE: New Firmware Version 1.4.5 just released...untested
