    So far, sooo much better than Govee for Home Assistant
    After getting a dud when I bought the A21 version of this bulb initially, got the A19 in today as a replacement. Unlike the A21, I was able to quickly find the local WiFi network of the bulb and connect to it on my iPhone. Once connected, I signed it into my WiFi network, then Home Assistant detected it shortly after.The speed with which the bulb responds to changes through the Home Assistant interface versus the Govee smart lights is amazing! The Govee lights were using bluetooth, as their WiFi would only work through their proprietary app.Now to start the process of swapping out all of my Govee lights for the KAUFs.

    Dim and prone to failure
    I bought these bulbs specifically to be used with Home Assistant because they did not require any cloud service out-of-the-box. Setup was fairly straightforward – connect to the bulb’s WiFi and use its captive portal to configure the main WiFi, then adopt into Home Assistant. That is as far as my commendations go.The bulbs are very dim, the color accuracy could be better, and within only a few weeks two of the four bulbs I ordered failed several days apart. Both times they were set to a 20% dim warm very light yellow for a few hours, they then suddenly switched to bright white in the middle of the night, and kept switching back to bright white whenever I tried to go back to the dim warm light yellow. They then began flickering shortly after, then completely lost connection with Home Assistant, and went completely dark. No light, no WiFi signal, no indication that they were even getting power.

    Absolutely love these.
    I use Homeassistant and these are super easy to configure and just work. We have a few of them now and are slowly replacing some main bulbs with these.

    Ok, but problems
    Seemed to have a mind of it’s own on the ESPHome software it came with. Works much better on Tasmota. Very easy to open the bulb for serial flashing, which is nice. Never seems to take an over the air update, it always resets the web interface when trying to upload on both ESPHome and Tasmota.

    Great but you should know what you’re getting into if you’re looking at these.
    My use with these bulbs is to have Tasmota installed on them. The firmware flashing process can be a bit tricky at times. For whatever reason of the 9 I installed 2 of them had issues taking an OTA Firmware in two different situations.Both of the two with the issue worked out of the box as expected. The SSID of the initial AP was broadcasting and I was able to configure the local SSID for communication. The problems happened after that.1.) One bulb worked as expected, the Webpage for the bulb was accessible and I could dim, color change, and turn on/off the bulb. But when attempting to flash the tasmota.bin.gz as I did with 6 other lights before it, the update would fail (RESET ACK on the connection) or the device would report a success but not reboot. Then manually power cycling it or rebooting the firmware from the webpage it would respond as though nothing happened (Original firmware). Updating from 1.851 to the latest (1.87) didn’t change this at all though it was curious that I was able to OTA the Kauf firmware but not Tasmota.2.) The bulb connected to my SSID and I could see that it was issued a DHCP Lease. When connecting to the page, it was returning data that couldn’t be deciphered by any of my browsers. But the REST API (ESP Home) was working. Sending a /reset didn’t seem to do anything to resolve this either (the command /reset did work as expected but didn’t solve the actual issue).Attempting to flash these using their OTB (Out of the Box) configuration portal (the time that you’d select the Local SSID) was also not working. As a result, I had to grab the soldering iron and FTDI Device to do the tasmota flash manually.Regardless, the OTA firmware flashing feature is a value add, not a product seller for me. As a result this doesn’t warrant any negative stars in my book as I knew going into these bulbs that I could do it manually if push comes to shove. Once Tasmota was on all 9 of the bulbs I installed, MQTT was set up and my HAOS was able to pick them up with no issues. Functionally they work well and I am happy with them. I’ll buy more as I work on other parts of the house.My only concern at this point is life-span. The assembly looks to be quality. The biggest thing that will fail is likely to be the power-delivery side of the device and only time will tell if these will last. At 10 a piece I’d like to get 3-4 years out of these, but we’ll see.Edit: I’ve now had 2-3 of these fail on me. Simply refusing to turn back on. I am confident I can probably fix them, but its really not going to be worth my time. At only about 4 months of use – its pretty bad that im getting units that are dying. Only reason I’m not going to lower by another star is because the majority of these are still functional so we’ll see what the next few months bring.

    Inexpensive and functional? Sign me up!
    I’ve only ever had Hue bulbs, and I’ve tended to avoid the WiFi bulbs since many of them use proprietary technology that makes it difficult to integrate into the rest of my automation system. I was super excited to hear that Brian Kaufman had released an A19 bulb, I ordered one immediately–and after installing it, ordered the 4 pack. Price-wise, at $12.50 apiece, they are pretty much a steal, and they definitely resemble the colors from my Phillips Hue lights that I have installed in some other fixtures.Against the official recommendations, I am using these on outdoor fixtures (they are covered and under a porch), and while I’m sure they will be alright, I would love to see some outdoor fixtures as well. Overall, I think I’ve found my go-to smart light bulb, and I’m looking forward to using them across the house–and incorporating it into a future light show with my WLED-based LED strips!
