I found a pair of these on Amazon for around $30 CAD (after a $2 coupon saving). They look like fun to install. I figured that now that I know how to installed Tuya devices with the Homebridge<\/a>, these would be great additions to the common areas of the house, should we need some colour added to our lives.<\/p>\n\n\n\n

Amazon was extremely helpful and these bulbs came the next day. Amazon Prime is such a great service!<\/p>\n\n\n\n

I proceeded to add these devices to the TuyaSmart<\/a> app without any issues. Tested the lights using the app. I then logged into the Tuya developer site to ensure that the new devices were registered.<\/p>\n\n\n\n

I provided the configuration into Homebridge using the following template from the homebridge-tuya-lan plugin page<\/a>. Unfortunately, the provided sample template did not work, because the datapoint identifier<\/code>, a terminology that represents a numerical id that uniquely identifies a specific device function, such as power on\/off the device. My vague understanding is that the OEM, in this case Teckin, can pick and choose the datapoint identifier<\/code> when creating their product, and map specific numerical values to the various functions of their devices. I gleaned this from Tuya’s developer documentation here<\/a>.<\/p>\n\n\n\n

Therefore, the provided sample of:<\/p>\n\n\n\n

\"dpPower\": 1<\/pre>\n\n\n\n
was simply incorrect. The dpPower<\/code> setting needs to have the correct numerical value that points to the power on\/off functionality of the device. The default of 1 was not working, and I now have the challenge of finding the right value.<\/p>\n\n\n\n
Through much research on Tuya’s site and Google, I found out that each device has a signature \/ schema. I found out that I can get the current status by executing the following command line (key and id has been replaced with fake ones):<\/p>\n\n\n\n
% tuya-cli get --ip 192.168.168.8 --key 8ddeadbeef5456ed --id 55deadbeefdeadbeef40 -a --protocol-version 3.3\n{\n  devId: '55deadbeefdeadbeef40',\n  dps: {\n    '20': false,\n    '21': 'white',\n    '22': 1000,\n    '23': 188,\n    '24': '00bc03e803e8',\n    '25': '',\n    '26': 0\n  }\n}<\/code><\/pre>\n\n\n\n
I then guessed that the datapoint identifier started with 20 instead of 1. Also based on the value of 1000 for dps '22'<\/code>, I also deduced that I had to change the colorFunction<\/code> from HEXHSB<\/code> to HSB<\/code>, because it was not using HEX to denote ranges. The last hint that I got was from this comment<\/a> on a forum. Ultimately, consolidating all of the above knowledge, I arrived to the final configuration that looks like this:<\/p>\n\n\n\n
{\n    \"name\": \"Smart Bulb 2\",\n    \"type\": \"RGBTWLight\",\n    \"manufacturer\": \"Teckin\",\n    \"model\": \"SB50 Smart Bulb\",\n    \"id\": \"55deadbeefdeadbeef40\",\n    \"key\": \"8ddeadbeef5456ed\",\n\n    \"dpPower\": 20,\n    \"dpMode\": 21,\n    \"dpBrightness\": 22,\n    \"dpColorTemperature\": 23,\n    \"dpColor\": 24,\n    \"minWhiteColor\": 140,\n    \"maxWhiteColor\": 400,\n    \"colorFunction\": \"HSB\",\n\n    \"minBrightness\": 10,\n    \"scaleBrightness\": 1000,\n    \"scaleWhiteColor\": 1000\n}<\/code><\/pre>\n\n\n\n
The lights finally worked with Homebridge and therefore also worked with HomeKit. I thought adding these couple of bulbs would be done in a few minutes, but it took a little more effort than I thought.<\/p>\n\n\n\n
I couldn’t be happier that they now work with Siri!<\/p>\n","protected":false},"excerpt":{"rendered":"
