The first of the two new lights I’ve just received is the Blitzwolf BW-LT21 Smart LED Light Bulb. Ok, so its a bulb… so what? Well, not only is the white very bright, the colours are bright, too. All too often with RGB bulbs, the individual colours are pathetic – not these. There is only one white – warm white – but that works for me. Originally I used this light with the Blitzwolf APP but there is a Tasmota template and that is now in use thanks to Tuya-Convert.
Next I have the BW-LT27 – colours not quite so bright as the BW-LT21 but this bulb has it’s own features like a full range of whites from 2700K to 6500K – AND it has a nice white infra-red remote control (no setup – it just works). There’s a Tasmota template for this one, too. Don’t underestimate the latter – i.e. Tasmota template complete with a set of rules to control the lamp with the IR remote and of course via WiFi/MQTT. Blakadder has done a great job of keeping these all together in a convenient place. I’ve done the conversion – it works. Thanks, Banggood. Both of these lights are E27 fitting.
Above, the BW-LT27 is all set up and ready for business with Tasmota, its IR remote and my Alexa Echo.
All in all a fine pair of additions to my collection. In the image above you see the BW-LT27 box, IR remote and my Tuya-convert rig comprising an otherwise redundant Orange Pi Zero (running Armbian) and a Wemos D1 ESP8266 board all contained in an RPI-case. I added a little flourish to the code and a function so I can start up the box, simply type “tuya” and..
Somewhat sadly – April 15, 2021, after being out of use, sitting on my bench for several weeks, I have to report that the LT21 is DEAD – it does not respond to Tasmota OR the Blitzwolf APP (and switching off and on several times in a row does nothing). It WAS working just fine on Tasmota but I’ve been playing with other lamps and now it is dead. With Tuya-convert no longer working – it looks like the BW-21 is dead in the water. Oh, well. The BW-27 however continues to work just fine.
