Thank you so much BearWithBeard for this, it's really helpful. I decided to try using a serial gateway and have had more success. The sensor is connecting and getting an ID from the controller.

Although the gateway drops out when i reboot my Pi and I have to unplug, reconnect and restart HA! Not the end of the world, and certainly better than no connection, but a bit annoying. I'd like to use an Ethernet gateway if I can so I'll try your suggestion of static ID's and see what happens.

I like the idea of organising things as you suggest, so may well end up doing that anyway. I'll try the static route to the gateway too if still no luck - very useful info. No capacitors at this point either. They are within a few metres of each other so don't think range is the problem. Will amend my HA Config as you suggest, again useful info. Only other thing I didn't mention is I'm using a shield breakout board on the gateway rather than the board in the tutorial, not sure if this affects power or is relevant!

Again, thank you, really appreciate your advice! I was completely stuck so really nice to have options now. OK I found the reason. Only 2 and 3 generates interrupt! Send update every two minute. Here I am again, I had a second node running and tried to make it battery powered but it doesn't seem to work on battery only. Anyway along the process of finding out what the problem is I encountered two other problems: I'm getting a ERROR accept: Bad file descriptor in mysgw, only 1 instance seems to be running though: Any suggestions on this?

Ss sshd: pi [priv] ?This Instructable shows how to connect a relay module to an esp, something that should be straight forward but needs a few extra components to make the relay work correctly if you're using the small esp device in the pictures.

This board was from ebay and has an AMS voltage regulator built onto the board so that you can connect it straight to a USB type power source. The board also comes with a little daughter board which has a CHG chip on it which allows you to plug the esp board into it and program it, and once programmed the esp can then be removed and used in a project.

There are upsides and downsides to this form factor which are that once the esp is programmed if you need to change some of your code you need to take it out of your project and plug it back into the programmer.

An upside would be that the esp device is smaller than a NodeMCU Devkit, so if you're tight for space this might be a good trade off. The circuit on the veroboard in these pictures is doing more than just the relay control. More on that in another Instructable later. Did you use this instructable in your classroom?

Add a Teacher Note to share how you incorporated it into your lesson. The emitter of the transistor is connected to Ground along with the GND pin of the relay.

The base of the transistor is connected to the control pin from the ESP via the 1K resistor. The collector of the transistor is connected to the control pin on the relay which is also connected to VCC via the diode. Its a very simple circuit which switches the control pin of the relay to ground when the GPIO pin goes high.

The sketch I've written for the esp also has code for reading the temperature from a DS18b20 and also detecting if the LED is on or off on the control box for my boiler, but I've removed this code for this Instructable and will include it in separate Instructables. You can change this how ever you want in the sketch, as long as you also change the home-assistant switch config too in Step 3. Reply 4 years ago.

Reply 2 years ago. Good job padeth I had been looking all over for someone who knew how to do this slightly different esp and relay. BTW sandipanc4 and jackyj6 you should probably stick with leggos. Hi looking for some help. I modified your sketch to manipulate a remote; however, it's jamming the HA switch.

It seems to be connecting but not working. Hi, I modified your sketch to operate a remote control; however, it appears to be connecting to the server, but when it does it seems to confuse it and the HA switch only stays in one position.

In fact it disrupts all other operating switches. I have problems with the Home Assistant set-up side. Could you please share the code to configure correctly the MQTT and the related switch in the configuration. What the hell is heating pin? Reply 3 years ago. That is the output pin that is connected to this relay he is using. IN this case rather than use the int '16' he used a variable named HeatingPin to store the pin number. The project doesn't work for me either, a bit more detail on the Home Assistant set-up side of things from the author would help.

The Google Assistant is an artificial intelligence-powered virtual assistant developed by Google that is primarily available on mobile and smart home devices. It can recognize your words better than any devices and respond fast and correctly to your commands. Users primarily interact with the Google Assistant through natural voice, though keyboard input is also supported. An applet is triggered by changes that occur within other web services such as Gmail, Facebook, Telegram, Instagram, or Pinterest.

In addition to the web-based application, the service runs on iOS and Android. A webhook in web development is a method of augmenting or altering the behaviour of a web page, or web application, with custom callbacks. These callbacks may be maintained, modified, and managed by third-party users and developers who may not necessarily be affiliated with the originating website or application.

In computing, JavaScript Object Notation JSON is an open-standard file format that uses human-readable text to transmit data objects consisting of attribute—value pairs and array data types or any other serializable value.

It is a very common data format used for asynchronous browser—server communication, including as a replacement for XML in some AJAX-style systems. First of all, We need to define some specific phrases for Google Assistant to find out what we mean.

After that we read data from database by ESP module and send it to the Arduino. First of all, you need a device to run your Google assist.

Wireless components are less reliable than their wired counterparts. Would you use a wireless smoke sensor in a factory? I don't think so. And why use a wifi magnetic door sensor in your home? What i did is an hardware component that can be connected via RS to a home assistant controller via the Modbus platform. It's based on an arduino. Did you use this instructable in your classroom?

Add a Teacher Note to share how you incorporated it into your lesson. Connect the Rs converter, a display if you plan to use it, relay s and set it up for push buttons. Don't forget to configure it before copiling. You need to set up the pins used as input, outputs, if it have a Temperature sensor, a display and so on.

Now you can see the temperature set point and control it. Set point can be controlled via automation script and from other components. Using a google assistant you can modify the temperature via vocal commands. By andrea Follow. It can act as a light controller via a relay and an input for the buttons. It can act as a remote switch via a relay and an input for the buttons. It can act as a thermostat. It can act as a temperature sensor.

Add Teacher Note. You need an arduino board. I've used an arduino nano but others will be ok. Edit the configuration.

I thought that I can extend my rpi's gpio ports with an arduino, so I plugged an arduino to one of the usb ports on the pi, and connected 2 HCSRs, 5 DHT11s and 2 mosfets for led dimming.

Because this is my first mysensors project, I have copy pasted some sketches together to control all of the sensors. Almost everything seems to be working fine, except the led dimming. It compiles and I can upload it to the arduino, all sensors are recognized by home assistant, but when I try to dim or switch on one led stripe the other does the same thing. This is the fourth or fifth version of the skecth I have now, but all seem to do the same, so maybe this is a problem with the HA mysensors integration So the question is: Can anyone see the problem with my sketch?

Yeah, but don't really know howto solve that. The arduino is plugged in to the usb port of the rpi, I have no radio whatsoever. So I remove all the serialprint lines from sketches, because they cause error messages in HA. Then I modified the above sketch with adding LedPin to the fadelevel function. That resulted in some strange working because I could switch the leds on and off, but the dimming worked on only one led.

Then I have duplicated everything. Made a fadelevel2 function, with requestedlevel2, tolevel2, and so on. Same result again. I am starting to think that there is a strange limitation in the arduino that I am not aware of. Like the motion sensors can only be hooked up to pins 2 and 3, so maybe the 9 and 10 pins are not that kind of pwm like the others.

I know it sounds dumb. I will try to separate the leds "far" from each other, so use pin 9 for one and 5 fo the other. This is an arduino uno btw. Had some time to troubleshoot my setup, and it turns out that my problem has nothing to do with mysensors As usual it was a user error. I have put both of the mosfets on the same cooler and the middle pins drain got in contact throught the screw that held the mostfet to the cooler.

Separated the coolers and voila everything works Yeah!I will spend this and a few upcoming posts with my Home Assistant experiments. Home Assistant is an open-source Python 3-based home automation platform.

The configuration is done in yaml-files and automation can be done by specifying triggers, conditions and actions. There are lots of available components from the Home Automation community:. I have some actuators and sensors at home that I control and monitor via services running on a Raspberry Pi.

I want to use Home Assistant for consolidation of these services and data in one place. I also want to use Home Assistant for future extensions of my smart home using z-wave. The configuration file for Home Assistant on a Raspberry Pi based on the tutorial mentioned above is located in:. By default, Home Assistant runs a discovery action for finding and integrating existing devices. It finds my Sonos and SqueezeBox systems. To view historical data 1 daya widget can be clicked to show a graph.
