Let's Control It

igorka

Hello chromo23 ! Unfortunately, I am now sorely lacking free time for hobbies. In addition, my prototype heater with a PID controller is not available to me... I also have a bad trait, namely, while I'm actively doing something, I remember everything, it's worth taking a break and you need to rememb...

Nice Idea, i will try this soon... I took the liberty to remove the unnecessary declaring of variables as TD-er suggested and did some formatting. (You wouldn’t even need to declare variables with 0 at boot, but i guess you know that...) Hi, the topic has stalled. To be honest, I myself have lost i...

The principles of regulation systems, their differences and features are simply described. With an emphasis on the PID controller.

It's good, but I didn't use his examples. I just gave a link to this guy's site, as he does smart things and is passionate about it.

Do you have a good source of information on how to tune the PID controller? In a previous job, I have been working a lot with PID controllers to fine-tune motor controllers on CNC 3D measurement machines (so called geometric metrology). However, I always found this tuning to be quite a lot of work ...

There is still an mismatch in endif's in your code This happened due to the fact that there was an error in the notepad, and there was code with comments :oops: :roll: . On ESP the code is flooded without error. Thank you for bringing this to our attention! In the first message removed unnecessary ...

For a long time I had a desire to make a regulator working according to the Proportional Integral Differential regulation law, abbreviated as PID. I will not describe here how it is better than the classic relay with hysteresis, whoever is interested will find the answers himself. The only thing wor...

An 'endif' is missing from your 'on rules#timer=1 do' rule, not sure where it should go, but that is a very likely cause for erratic code behavior. Finding such errors is much easier when using systematic indenting of your code. You are absolutely right, missed 'endif' :!: Thanks for the tip ;) . I...

igorka

There was a following problem and lack of its decision. So I'm asking for advice and help. It is worth mentioning that the code contains and repeats "redundant-superfluous" lines of code, this is done in order to deliberately exclude the influence of commas in numbers. I assigned values to...

igorka

Thank you. There is good news. :) The recording works as it should: let,1,26.6 let,1,[var#1]*10 // let,1,266//result // let,1,[var#1]/10 // let,1,26.6//result This entry works too: let,1,26.6 let,1,[var#1#F] let,1,26//result This entry works too: let,1,26.6 let,1,[var#1#D.1]*10 let,1,266//result

Until recently, I had no need for calculations and therefore did not know that an unpleasant surprise awaited me :( . Next, I will give examples of what you need to pay attention to and whether such calculation logic will suit you. I do not rule out that for many this will not be a problem, but ever...

igorka

Indeed there is no %i1% notation and to be honest, I don't know why not.... It would make sense to use an integer value for indexing like this: [var#%i1%] instead of [var#%v1%] But that's about the only really use case I can think of where the [int#X] notation cannot be used and integers are needed...

igorka

Maybe it's funny... The fact is that in the "C" programming language, it is considered a correct entry: x+=y; x=x+y. And that's why I make a lot of mistakes... It is also more usual to give names to variables, this also forces you to change the usual approach for writing code. Thanks for t...

igorka

Assume you have something already in [int#1] The "let" command does all computation things you throw at it. The % is the "modulo" operator. let,1,[int#1]%2 if [int#1]=0 logentry,"even" else logentry,"odd" endif I know that I'm asking a question in the wrong t...

igorka

What do you mean with „is just a tip“? Sorry, I meant something else. Google translit translated it wrong. I wrote that the ADC input does not receive a useful signal - interference. And if this is true, then after you connect the ADC pin to the GND bus, the value should be 0. Just make the wire as...

igorka

Try to close the ADC output to GND, the value should be 0. It seems that the ADC value is just a tip.

igorka

You're probably right. But 512 kb will be available for the file system.

This is an ESP-07 module, unfortunately it has only 512kb of flash.

igorka

In this particular case, the solution with this plugin is completely suitable for me. But let me express my opinion or even wishes. It would be very convenient to be able to (command) save user variables "Let" in flash. After all, there is certainly a need to work - to operate not only wit...

igorka

Thanks! I will definitely do it later.

There is a problem with setting the value using the configuration command. The picture shows the settings of my plugin: 1.png I enter the command config,task,thermostat,28.00,temperature: 2.png The value does not change. As it was 24, so it became, the temperature is also maintained at 24 degrees. A...

igorka

I will be grateful and grateful to you if you create an assembly for me. But after all, the plugin can be used without a display? I don't have it and I just don't need it in this product.

igorka

Can you elaborate? I don’t understand what you mean. It's very simple. I use the ESP-01S module, with an expansion board for it (relay module). By default, the relay is controlled by GPIO.0, and the circuit design of the relay module is such that in order to turn on the relay, on the GPIO.0 you nee...

igorka

Thanks. I will definitely try to test this plugin!
Another question: I have reverse control, logical zero is included, logical unit is disabled. Is it possible to set these parameters in this plugin? Or will I have to do an inversion at the output through the rules?

igorka

That's not correct (I corrected it in my sample code), should be: I have corrected according to your example. Now everything is correct. Not sure what you mean with "re-recording" ? This is the right question! I mistakenly assumed that after the power was turned off, the contents of the v...

igorka

That should be something like this: Thanks! That's exactly what I wanted. So I made a re-write protection if the value has not changed: On heater#ustlow do logentry,"MQTT import ustlow: %eventvalue1%" if [telephone#low] = %eventvalue1% tone,3,150,100 else TaskValueSet 3,1,[floor#temperatu...

igorka

Please excuse me, I didn't understand you well (Google translit). Or I don't speak well... I need to set thresholds for turning on and off the thermostat from the application in the phone, using the mqtt protocol. To do this, I created a dummy device where two variables are low and high, how can I s...

igorka

You should have a look at P109 Thank you friend! To be honest, for my solution of my problem, this approach is redundant. It's more visual and informative with the display, but I don't need it, the mqtt app on the MQTT Dash phone is enough. It is very simple and probably this is its minus, at the s...

igorka

You can also store the set value in a dummy, which will be kept even after a reboot or crash. As long as you don't have a power cycle... but then you probably also would have lost the settings on your thermostat, so your wife will probably accept that as an excuse :) You can explain in more detail ...

igorka

Anyway, let's not make things more complicated. Just keep in mind that color mixing with light differs from color mixing with paint. :) Of course we won’t, because you explained everything to me very sensibly! Thank you for your help! Also, I don't fully understand the color codes if you put it thi...

As you can see, the result is the same. Does it work if you use "on Led#Hu do" ? Hooray works!!! You're a magician.Very complex code, I would never have thought of that. Screenshot_3.png I looked at the NeoPixel library and there in my opinion there is a convenient option for recording co...

This is good news for anyone who uses ESP Easy, but bad news specifically for me. For reference, which ESP controller card are you using and which pins are connected to the I2C bus?

In the photo, there is a signal from the output 32K of the DS3231 module.Based on this, I am more and more inclined that the problems are in the firmware or ESP-01S.

Do not pay attention that the signal is bipolar, the oscilloscope input is closed.I forgot to turn it off...

igorka

Sorry for the question. I wanted to know if you managed to start the DS3231 correctly?

igorka

For example a loose ground? No pull-up resistors on the SDA/SCL lines? No, that's out of the question.Everything is on soldering, there is good contact everywhere.This is a photo of a mock-up for experiments.I specially assigned SDA and SCL to the RX, TX contacts so that external components on the ...

If you uncheck the "Enable Serial port" option on the Tools/Advanced page, you can use those pins. Yes, yes, you're right.I did it earlier and wrote about it, this is my mistake :cry: . Можете ли вы попробовать это? Unfortunately, this did not help, the RTC does not work, perhaps this pro...
