The story goes on, and my opinion of August may be changing.
I had pretty much resigned myself to simply using the mechanics, connecting the motor up to a home brew ESPHome device. Looked easy enough. Remove the small circuit board inside, bring the motor leads out, done.
But rather out of the blue, several days after my initial contact, August emailed to say they'd reset the device, which is to say, they did something in their database, and I should try to initialize the device again. And it worked! I have a working lock, that I can open and close by Bluetooth!
Yay!
However, I want to have Home Assistant to control it .. close it .. and that required the setup of the included WiFi bridge.
Which didn't work.
This is a device roughly the size and shape of a USB charger.
Pretty simple initialization. Step 1, press the button for 5 seconds, wait for the LED to flash. No flash. 10 seconds, 2 seconds, 30 seconds, 2 minutes, no flash.
"She be dead Jim"
So I took it apart; nothing to lose after all. Inside I found two circuit boards. On the bottom was a remarkably complex power supply board. Components on two sides, 30 or 40 components in all. It attached via a 6 pin connector to the INCREDIBLY complex digital board.
I was able to determine that 2 of the pins on the connector supplied 3.3 volts, so this repair wasn't going to be just a simple fuse replacement.
Examining the digital board, there were again components on both sides. Half of one side is obviously the radio portion, with an 84 pin device taking up the rest of that side. The reverse has a 64 pin IC, a 48 pin IC, half a dozen other 8/14/16 pin ICs and dozen or more caps and resistors.
I was, quite frankly, astonished at HOW MUCH ELECTRONICS were packed into this little package. Suddenly, the $100 replacement cost didn't seem so out of line.
I put it back together to find that it still didn't work (no surprise) and started to get depressed again.
As I was packing it all up, I noticed on one corner of the box the word "ZWave".
Cheering up again, I emailed August support and they confirmed that this device does in fact support ZWave. They then sent along detailed instructions for linking the lock via ZWave, including the specifics for use with Home Assistant.
Holy Crap! You usually get Apple and Amazon instructions, but they included HA as well.
So I ordered the HA recommended ZWave adaptor. In for a penny, in for a pound. It's roughly the price of the August WiFi bridge but of course lets me add other ZWave devices. (Right now I'm mostly Zigbee, some WiFi.)
The adaptor should arrive today, and by tomorrow, I'll either have thrown good money after bad or I'll have a working lock.
I have to say, August tech support has been very good. 5 out of 5 stars.
My opinion may be changing.
