Air Quality Egg - Failed to Publish Heartbeat

RSSI of -46 is really good (it's in units of dBm, so closer to zero is better)... so it's not that...

The instructions go something like this:
1. Follow the instructions through step 8 here: http://shop.wickeddevice.com/2015/08/26/re-programming-an-air-quality-egg-v2/, except for the boards manager URL use http://update.wickeddevice.com/package_airqualityegg-2.1.8_index.json.

1. Download this sketch from Git-Hub: https://github.com/WickedDevice/AQEV2FW_PM_ESP, and use it in place of step 9 to load the latest software onto the Egg.

I need to get around to promoting the latest software for an Over-The-Air update, but I need to do some more testing first, so I'm not exactly sure when that will happen. If you can manage the above yourself, that would be the shortest path to victory.
