Hi and thanks for the Video @netmedias. I am trying to use this with Blynk and Alexa so I don't require any MQTT support, but I am having trouble figuring out what support libraries need to be downloaded from github. For example, where do I find the "hw_timer.h" library? How do I install the whole library package? Thanks for any help you can give.

@carlborgen 5 лет назад

I see that your light has a fade between states, and I can't see that functionality in your nodemcu code, is that a feature of the espalexa? Since I'm trying to make a slow wake up light dimmer, I'm trying to figure out whether to put that functionality locally at the node or have it in home assistant somehow.

Please take a look at "robodyn_dimmer.h" file. byte fade = 1;

@paslertomas 5 лет назад

Hello, I like this project a lot, i have a few questions on you about. Is it possible to use D1mini board instead of nodemcu? Is it possible to add a external button (mechanical push button attached to board) for turn on/off output? I am using HA with mqqt broker installed on it, and using tasmota on my mqqt devices. But tasmota doesn't allow to use dimmer like this. So i found your awesome project. But i am not so well in coding sketch like this. I think it should work, but D1mini has different pins, so. I am looking for your answer. Keep up doing things like this. It is awesome :)

@netmedias7657 5 лет назад

Yes, you can use Wemos d1 mini and use it as 3-way switch. You will need to do current sensing and modify the code to handle it. I will be doing a tutorial on it soon. In meanwhile you can check out my 3-Way switch tutorials. Good Luck. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-5SgB6wzgxY0.html ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-QaY5m5RmB7M.html ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-_jeQWu23xqs.html

@MarcoAntonio-nw2dq 5 лет назад

When installing the bulb on the ceiling of the house, does the esp8266 need to stay on 5v or will it be powered by the ac dimmer board?

@netmedias7657 5 лет назад

Marco Antonio No. You will need to supply 5v if using NodeMcu or 3.3 to plain ESP8266.

@@netmedias7657 I look forward to it, and keep it up! Thanks to you I was able to automate the whole room and part of the house with ALEXA, now I am focusing on the reinforcement of the security of the network to counteract any possible infiltration, I know that it is paranoid but it is not too much to be prepared.

@netmedias7657 5 лет назад

Richard Mequert you are right to be concern about the security of your network. It does not matter how secure your network is there is always a chance that it is hackable by hackers but you should not worry since we are at bottom of the hackers list.😄 I am planning to start making my projects secure by using SSL and fingerprinting methods. So stay tuned. Thank you for your valuable feedback and good luck with your projects.

my lecturer ask me to control the brightness of the lamp using triac and zero crossing detector circuit.. im a little bit lost since im an electrical student not electronic 😂😂

@netmedias7657 5 лет назад

Yes, You can use UNO (use the Arduino timer) and connect it to ESP8266 for wifi. I did a tutorial on Uno wifi with NoduMcu. You can use the same code for ESP8266. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-SiU-QZwik8w.html

@netmedias7657 5 лет назад

This is exactly kind of circuit you need for a zero crossing detector. You can use this module it is around $3. If the requirement is to build your own then get the module and take out the parts since it will be cheaper and design your own PCB and use the parts. Also tracing the original PCB will help you with new PCB tracing or breadboard hookup. You can use the same code and your project is complete with some modification. Good Luck.

@@alizafar5732 As Netmedias said , you have to change the Frequency of the PWM Signal that comes from the ESP8266 modul. Normaly it is set to 21 kHz, aczeptable operation range is 21 to 28 kHz. Best will be 25 kHz .Search for changing PWM Frequency on a Arduino. I can´t remember what was the correct line in the Setup Section in the Code. But it is only one C-command in Setup. Look this video it shows you what Netmedias mean with noise . ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-AEJ8MQyEOBg.html Then you have no noice when the Fan is on low speed. Rgds Juergen
