Let's Control It

rudloffl

I like the idea, but it's way beyond my skills ! Thanks for your input.

Would use a GPIO "high on boot" such as SD2 or SD3 help me in your mind? I will test and let you know

Thanks again

rudloffl

I agree with your idea, but I was looking for something more elegant. The led is only draining mildly the battery, I would like to make sure there is not something more consuming running in the background (and is most likely consuming much more than the led). My project was up and running all night ...

Hello all, I'm working on a project I called "growinator" (esp + PCF8591 with 4 soil moisture sensors) :D I will use the deep-sleep model, but I noticed that when in sleep mode, the LED on the PDF8591 is still on (therefore draining the battery). I'm looking for a solution, but I need your...

rudloffl

Yep ! I took of the jumpers and it works !

Thanks

rudloffl

I kept the jumpers.

I will test tonight and keep you informed.

Thanks

rudloffl

Very old post, but always good to ask.

I get a similar problem (see here viewtopic.php?f=5&t=7364), do you have a solution ?

rudloffl

Hi all, I'm working on a device that will monitor the ground moisture and pilot sprinklers. I'm planning to have 4 sensors ( https://www.amazon.com/Gikfun-Capacitive-Corrosion-Resistant-Detection/dp/B07H3P1NRM/ref=sr_1_1?keywords=ek1940&qid=1579233908&s=industrial&sr=8-1 ) with a pcf8591...

Hello all,

I have a LED strip controller, and I would like to create a rainbow/random feature (via a rule).

Is there a feature in the rules that can create a random number (I have not found it here https://www.letscontrolit.com/wiki/inde ... rial_Rules ?)

rudloffl

did you use that scheamtic https://www.letscontrolit.com/wiki/index.php/Relais ? The PCF is powered via 3.3 but the relay board is powered via with 5V VCC/JD Are you powering the relays from the PCF8574 or are you using the JD-VCC on the relay board ? I took off the jumper and power the relay direct...

rudloffl

Are you powering the relays from the PCF8574 or are you using the JD-VCC on the relay board ?

I took off the jumper and power the relay directly

rudloffl

Victory !!!

I got it to work, I "just" had to change teh mode2 to "0x14"

rudloffl

I used the espesy GPIO directly to control the transistor and it works perfectly fine.

However, I would like to understand why I can't get the PCA9685 to work.
Do I need to had a small transistor between the one controling the 12v Leds and the PCA ?
Any idea what I should do to get it to work ?

rudloffl

Did you find a solution ?
I might have a similar problem with the PCA9685

rudloffl

I will try to control LEDs without the PCA9685. Let me know if I should use a different piece of hardware.

Hello all, I'm working an a led ribbon system that will communicate with my home automation system (Jeedom via generic HTTP). The home automation system can easily populate colors code (RGB) in hexa, e.g. #FFFFFF. I want the espeasy to read the code directly. Is there a formula (not listed here : ht...

rudloffl

Hello all, I need some help to get my project to work. I want to control a LED ribbon (12v) from a wemos D1 (with the latest Mega) via a PCA9685. It's highly inspired from that https://mellbell.cc/blogs/projects/rgb-thermometer-using-pico . I cant find the solution to control the transistors from th...

rudloffl

I actually have an other problem... When I power up the complete system, the relay is changing state --> it is a big problem when you want to use it as a controller for the garage door. (I risk to open the garage each time there is an outage, a reboot has no effect) Is there a work around to make su...

rudloffl

I got it to work with a 10K and 330ohm. Thank you all

rudloffl

Do I need to a dd a 10K resistor like in this example ?

rudloffl

The relay will be activated with the +5V (or3.3V). Should I wire it like add a resistor somewhere ?

rudloffl

Hello all, My question is not directly related to espeasy, but I'm sure someone knows the solution to my problem. I want to actuate my relay via a PCF8574, the relay is a "single" version (one relay on the board, with 3 pins: a VCC, a GND and a S). The relay is connected to the 5V and the ...

rudloffl

Indeed... I have been overthinking... Just for my curiosity, is it possible to monitor a PCF8574 like described here ? https://espeasy.readthedocs.io/en/latest/Rules/Rules.html on System#Boot do Monitor GPIO,15 endon on GPIO#15=0 do if [Plugin#GPIO#Pinstate#13]=0 // do something endif endon on GPIO#...

rudloffl

I'm back to that project ! Here where I am: - 2 distance sensors directly on the esp - 1 PCF8574 for 2 relays (both are OK and functional) and 1 for a PIR and a door sensor (those are less ok...) Here are my questions: - How do I monitor a PCF port ? What I tried below does not work? - Is the monito...

rudloffl

I'm not a big fan to hard code a API key in an espeasy (no offense to the team !).
I'm using Lunorak's plugin for espeasy (using http general). I prefer to avoid the usage of a different plugin on the jeedom side.
TD-er provided a solution with taskrun

Thanks again for the feed back

rudloffl

Yep, exactly what I was looking for !

Taskrun works as expected, many thanks

rudloffl

Hello everyone, I'm still working on my sprinkler system (8 relais + 8 buttons + LCD display). I'm storing the value of the active sprinkler in a dummy variable (1 to 8), and I would like to update the controller (jeedom over general http) immediately. I can use the interval update to put lower refr...

rudloffl

Did you find a solution @cdx ?

I have the same problem, I was hoping that a publish would do the job.

rudloffl

I have to put that project on hold for now (Sprinkler is the priority, the grass is not getting any greener...)

I have never heard of easyEDA, I will play with it

rudloffl

Thanks for your feedback Thomas, it helps a lot.
I will update the code and keep you informed.

rudloffl

I think the problem comes from my schematic (the short test I did over the HTTP are ok), see the code below. What's the best way to connect a switch to the pcf8574 (where to put the resistor) ? On System#Boot Do event,alloff endOn on button8#State Do if [button8#State]=1 Event,button=8,5 endif EndOn...

Let me know if you need anything else

Hello all, Still working on my sprinkler system. The esp8266 is connected to 2 PCF8574 (relays and buttons), 1 LCD display and thermometer (GPIO).

Thanks for your feedback. I will work on a proof of concept

Hello to all, Is it possible to use an IO extension (Via i2c) and connect to it distance sensors or PIRs ? I would like to automate my garage door and might be short on IOs for my requirement: - 2 distance sensors (2 IO each) - 1 PIR would be great (an other IO) - 2 relays (those will be on an IO ex...

rudloffl

Does a timer set to zero trigger the rule ?
From what I see No, but I want to make sure.
Thanks

rudloffl

I can control via http with:

Code: Select all

http;//...event,RelayToggle=1,5

rudloffl

I have done some progress, below is my code inspired from what you shared. What it can do: - It can switch the relay each time you press a button - Works with 2 zones, should be able to expand to 8.... What I can't do yet: - Control the system via http, I tried a "http:// ....PCFPulse,9,0,250&q...

rudloffl

Thank you Grovkillen, I will work on that solution.

Really appreciate the help, stay tuned !

rudloffl

by "internal variables" you mean "Generic - Dummy device" ?

To control the relays with my home automation service, can I overwrite the press-button status via http ?

rudloffl

But I need to transmit the relays status. When you say "internal", you mean GPIO address directly in rules ? I can try to use devices for each press-buttons and publish the relays status via rules. I have to make sure they will always stay synchro (actual relays status vs info that rules a...
