Sure thing. Where should I put this blog post, under support? Thanks!

Thanks! I believe I may have found a source for the ESP04, I placed an order and am waiting to hear confirmation.

Do you have any instructions on flashing the ESP module when it arrives?

I’m including some photos. I disconnected the sensor as to not break the wires.

Thanks,

Adam

I didn’t see any corrosion or broken solder joints; I reflowed it just in case and got the same result. Is it possible to buy a replacement board? I’ve search around but could not find a provider that had some in stock. Are there any alternatives?

I would like to at least attempt to flash it rather than just let it go to waste, so any firmware would be greatly appreciated.

Thanks,

Adam

Thanks Wolferl.

I was able to get it back online, although it’s not an ideal setup. I had to add an old wireless access point to my network. I had disconnected the A3 while redoing some things in my shop and after reconnecting it would not connect (or stay connected long enough to test). The only thing I had changed was to update my network to use Unifi instead of the older Asus hardware. I installed an old mobile access point and voila it reconnected. Will the hardware support more modern wifi networks if I updated the firmware?

How do I go about getting updated firmware?

Thanks,
Adam
