@Fat-Fly I would suggest the Actuator to drive solar panels. But it seems like you already found it a while ago...

Yes. I find. I want to test this mpu9250 but some errors.

Trying this build but getting the following in the serial monitor

MPU init: 0
Free mem: 1144
AWI Orientation

PWR led on the sensor is on but not getting any readings

Found the error.
Wiring diagram is incorrect
It's not 4 and 5 but A4 and A5

Hello. Any news from this project? Do you made the changes for the timer TLP?

@Ron said in Capacitive Soil Moisture Sensor: @Puneit-Thukral Thanks. I am not quite sure, so correct me please if I am wrong, but I think I am already using the MiniCore bootloader with platformIO. Or do I need to configure to explicitly use the MiniCore bootloaders? Also I have set BOD to disabled as I read somewhere that no BOD can also save battery. hi I'm not sure, but I believe I'm already using the MiniCore bootloader with platformIO. Please tell me if I'm incorrect. Is it necessary to set the MiniCore bootloaders explicitly?

Hi! I have the same problem as terxw. allpcb.com is missing the "NC drill date". Unfortunately I am not able to create this on my own. Can anybody upload this file? Thanks

@krisztian Hi krisztian, the singleLED board - as its name suggests - features only one LED output. If you want to have a setup with multiple LED strips you need to design a board with multiple outputs. I have already designed a board with 4 outputs, but I haven't built it. In terms of software you need to register multiple sensors in your program like this: #define numCh 4 //the number of outputs const byte ledPins[] = {9,6,5,3}; byte ledLevel[numCh]; boolean ledDimWay[numCh]; //in the setup function request the dim levels from the gateway for(byte i=0; i<numCh; i++) request(i, V_DIMMER); //in the presentation function register multiple lights for(byte i=0; i<numCh; i++) present(i, S_DIMMER); //if you receive a signal, you need to check for the sensor id setLED(message.sensor, requestedLevel); //to set the LED level (function: setLED) you need to use the sensor id to determine brightness and pin //Fade LED to set level int delta = (level - ledLevel[child]) < 0 ? -1 : 1; //Write to LED analogWrite(ledPins[child], map(ledLevel[child],0,100,0,255)); I will probably publish the whole code once I have built and tested the 4LED controller (i call it "MySensors rainbowLED") Hope I could help you ThetaDev

@Roland-Wijnen Hi! Were you able to compile the available files? I tried, but there has been a lot of error!

Hello all, I studied a little bit more this part of the circuit and it's a standard self oscillating flyback converter or a ringing choke converter as others call it. Indeed it provides the most compact solution for space constrained designs. But all of this comes at a cost: it's difficult to obtain a stable circuit and it has to be tuned by trial and error - at least this is what the literature says. I'm not a switching power supplies expert here(even though I want to learn more about SMPS's in general but my time is limited for now) but I've come to a conclusion: it's difficult to tune this or to change the existing circuit to accommodate the mysensors circuits power requirements. I tried various combinations using sleep schemes and to change the flyback converter components as other mentioned in the mysensors forum and indeed I can power up my custom design that is presented in this thread BUT it's NOT STABLE. From time to time the switching transistor(mje13003) burns out and this is because I removed the resistor placed at the input of this power supply - near the bridge rectifier and replaced it with a wire(this is not the same resistor as @Lukaspp replaced from the base of the transistor which is the startup resistor for the flyback converter). Now the only purpose that I imagine for this resistor is to suppress the transients - but it has a big value(100Kohm) which limits the current to a non-usable value for our purpose. I know that there are other solutions to overcome the transients but they are either bulky or too slow for this(correct me if I'm wrong here). More than that let's not forget that we have 2 power supplies here and when the lights go on the first supply(flyback) input gets shorted by the relays contact(I have the relays variant btw not the one with triac) so I'm thinking that other transients appear here as the primary inductor doesn't like that as far as I know - so I assume the above mentioned resistor of 100Kohm comes into play here too. Another role for it would be to limit the inrush currents. I played with that value too but it needs to be very low to have something stable and I got a value around 200ohms but that doesn't help as it's too low and after some time the resistor burned up and saved my transistor :simple_smile: . Now with all the tricks in the world and tuning the flyback converter to give more current this won't help as again let's not forget we have a SERIES circuit here so without external intervention we can't achieve that(only if we break somehow the laws of physics or maybe my thinking is limited :simple_smile: ). In this case the external capacitor placed across the light bulb comes into play to supply enough current to the standby circuit which is our flyback converter over here. I played with that one too and from 0,47uF I got to 4.7uF to have a decent result - but this one gets bulky and more expensive from obvious reasons. And let's not forget that the light bulb itself has some impact overall because this is the actual LOAD that we want to control and there are various light bulbs over there with various requirements. More than that they have their power supply embedded which in most of the cases is a(you guessed maybe): a self oscillating FLYBACK CONVERTER or similar. So this one too has inrush currents, transients which are sensed down the line to our dear Livolo switch and affects my custom board stability again :simple_smile: - isn't life beautiful? :simple_smile: So far these are the results of my trials and none of them proved to be stable so I kinda gave up on this and will try to use a normal powering scheme somehow(as Sonoff switches with a battery powered touch switch on the wall). Not the best solution of all but this is what you get when the infrastructure wasn't thought for this scenarios from the beginning. The Livolo guys thought of all of this I assume so that's why they stayed only with a simple circuit - a PIC mcu which maybe sleeps most of the time and a simple radio receiver which draws around 5mA or even less - so yeah that's why this works and it's stable in its original form.

@scurb This looks very interesting and my factor now to save me from having to create my own :-). I have been planning to do the same thing (although maybe on a smaller software scale) by writing a simple Python server that would pull serial packets off of a gateway arduino (either running mysensors or something I write myself) and pipe this through MQTT to openHAB. I have two questions: How do you interface with a sensor network? Do you go through a serial connection to read the serial packet format (a,b,c,d)? I see several implementations that put the mqtt client directly on the Arduino, but it seems much cheaper for me to just plug it into a USB port to get a virtual serial port instead of investing in a separate ethernet shield How does an item configurations look like for a switch in openHAB? I'm looking to build a toggle switch which toggles light on or off every time it is activated, and I cannot really understand how to configure the switch to allow this behaviour for an mqtt input. Feel free to take the second question with me directly since this might not be very interesting to the others in the forum
