Furthermore white-light color-temperature should be adjustable. For party and effect purposes the ceiling lights should be dialable to any colour. To accomplish this, 2 LED strips will be installed in each ceiling light. 2.5m [[https://www.aliexpress.com/item/5m-4-color-in-1-Led-Chips-RGBW-RGBWW-5050-SMD-Led-Strip-DC12V-Waterproof-Non/32699614057.html|RGB+CoolWhite]] and 3m [[https://www.aliexpress.com/item/50m-5m-roll-led-smd-waterproof-5050-60leds-m-dc12v-14-4w-m-flexible-led-strip/1562140605.html|WarmWhite LED Strip]] for each light. They will be controled with a [[https://www.aliexpress.com/item/RGBWW-Strip-WiFi-Controller-1-Port-Control-200-Lights-Communicate-with-Android-Phone-Via-WLAN-to/32502007408.html|ESP8266 based H801]] for each light. Thus we can choose colour and white-colour-temp for each light. {{/wiki/lib/exe/fetch.php?w=600&tok=48085b&media=roomauto:ceilinglights_great_again.jpg|ThePlan}} ThePlan * Comment 1 (xof): the fuse switches Basic- and fancy lights! * Comment 2 (xof): the power supply of the basic lights have severe distortions/interferences on the power lines!

Test various possibly installation locations to improve WIFI reception. e.g. put H801 outside light-metal-casing and under gypsum-ceiling plates or outside light-metal-casing and visible next to light. * tested in Leinwand/Mitgliederregal Ceiling Light, which is known to have worst WiFi reception from years ago TP-link Test.\\ Works Flawlessly :) - (done) reflash and write new trusted firmware for H801, so that it can be controlled via MQTT and remembers a default light-setting * see [[http://hackaday.com/2015/08/25/esp8266-in-commercial-products/|HackADay-Artikle]] * see [[https://github.com/4ndreas/WiFI-RGBWW-module|OpenSource Firmware for H801]] * see [[http://www.esp8266.com/viewtopic.php?f=13&t=7409&p=59978&hilit=RGBWW#p59978|esp8266 Forum]] * see [[http://domoticz.com/forum/viewtopic.php?f=51&t=7957|Protocol Documentation]] * see [[https://github.com/open-homeautomation/h801/blob/master/basic/basic.ino|Ready Made MQTT Firmware]] * (check) use [[https://github.com/SmingHub/Sming/|Sming]] * (check) use [[https://github.com/StefanBruens/ESP8266_new_pwm|Sming new PWM Lib]] with compile flag * (done) on power-on default-light setting is used * (done) MQTT commands * action/ceilingN/light {“r”:int, “g”:int, “b”:int, “cw”:int, “ww”:int} | N={1..6,All}, int={0..1000} * optional: “flash”:True or “flash”:{“repetitions”:x, “cc”:[topic2, topic3, …]} * optional: “fade”:True or “fade”:{“duration”:ms, “cc”:[topic2, topic3, …]} * specifiyng cc will forward the json message to the next topic in the list after the effect has finished or was interrupted * action/ceilingN/defaultlight {“r”:int, “g”:int, “b”:int, “cw”:int, “ww”:int} | N={1..6,All}, int={0..1000} * (done) provide backup interface. e.g. telnet * (done) backup telnet interface - (done) test in dry state * startup behaviour: PWM pins start in INPUT direction, all channels except R- light up for 700ms \ –> prefer solution where H801 soft-disables the LEDs and itself stays powered versus being powered on/off constantly * startup behaviour: configured default light state apply’s really fast after about y1.4s (not after blinking due to INPUT direction though) * WIFI connection (with DHCP) works really fast. takes about <=6s * MQTT works really well * Telnet configuration works really well * spiffs flash-time pre-configuration works really well 4.(done) test in indirect ceiling illumination configuration * Strip1 (RGB+CW) width: 12mm * Strip2 (WW) width: 9.5mm * all in all not bright enough for that and not diffuse enough - (done) test in ceiling light enclosure * WIFI works really well, surprisingly no problem - (done) Testinstall one in ceiling light * installed in middle-membeshelp light.
