Hello everybody, I was using the MH-Z19 sensor since several months without any issue. I did not have any issue for its calibration until now but, for some reason, I decided to update the ESPEASY version of my Wemos D1 board. I used the latest version on the github. Unfortunately since the update I ...

Hello,

Does somebody succeed in building a plugin for such a sensor ?

Thanks

did you get it running?

Not yet, I am really on late on my projects...

I think that I will go on on it within few weeks !

The cheapest board that integrates this sensor I found is this one : https://www.aliexpress.com/item/Magnetic-Encoder-AS5048A-for-Alexmos-BaseCam-Electronics-Gimbal-Controller-and-Brushless-Gimbal-Motor/32834461450.html?spm=a2g0s.9042311.0.0.3TtrJY I also found a library but it seems not OK with the...

Hello everybody,

I have a question regarding the promising magnetic rotary encoder AS5048B.

Does somebody already work on a plugin for such a sensor ?

Many thanks

What a good news !!!

I am not able to compile the last dev by my own with Arduino IDE :

"make": executable file not found in %PATH%

Tried many different libraries and different board version

Somebody has an idea because I'm dry...

Thx for reply. I have loaded test file into nodemcu v3 and there is no change. Still can't read sensor values. Only in logs I see messages “MHZ19: Unstable reading, ignoring! PPM value: 776 ...." PPM and Temp in logs are changing but each read of sensor values report "Unstable reading.......

I was about to forget that Espeasy does support json request so I know now how to retrieve the data !!!

Well, I compiled myself the core of version 2.0 dev 12 with the plugin of the branch "2.0" because my sensor is the B version and it's only supported by this plugin. I compiled a 1024 bin but this is not that important. But I though about that today, I recently wasted my time in having a l...

OK thanks, I'll work on it.

I saw that the frame sent by Espeasy is like "0, 3.2;10.7" which is quite uncommon

Now I just have to find something which fits to it !

Looking at the pinout of the Wemos: https://wiki.wemos.cc/products:d1:d1_mini Only thing that looks different is that that port has apparently a pull-down resistor. (D3, D4 have pull-up) Maybe the Wemos dus activate that pull down resistor during boot, which may cause strange things? I have a littl...

I have both sensors here (MHZ19 and -B version). In one system I use these pins: D5 GPIO14 D6 GPIO12 And in the other system: D3 GPIO0 D4 GPIO2 (BUILTIN_LED on Wemos D1 mini) I think you could try D5 and D6. Are there other plugins active? Perhaps try to disable them, just for debugging. Right, Min...

Well you know, from my side I am clearly not capable of working on such a code so... Unfortunately I can't help But I am very thankful for people like you who can and do so I am happy, I am enjoying your work in working on little project with them So I am waiting for improvement but many thanks for ...

(which reminds me, I still have to finish my code to switch the laser off between measurements) That's exactly what I was wondering... If the laser of the SDS011 was turned off between measurements. So I have my answer now Its lifetime actually would be less than 1 year. Your code update would be a...

OK, the board is still running after one night ! I did not try to unplug and replug it as I am afraid of the board won't boot. :D In fact you're right, I would have a scientific approach so... Wemos built-in 5v regulator is given for 500mA : - DHT 22 : 5mA - SDS011 : 220mA peak - MH-Z19 : 150mA peak...

Ok well, it is working since about 10mn... I succeed in compiling a dev12 version with only the needed plugins Strangely I had to disconnect the 3.3V power from the board (supplying DHT22 & OLED screen) to be able to boot the Wemos... :?: :?: :?: I will try to let it runs this night to check if ...

Well, even with the bin of the dev 12 version, it still has issue... On 2 different Wemos Sounds like Wemos issue... Or a problem with my routeur because the wemos seems to work well in AP mode OK.......... Well..... I spent about 5 hours on this issue... Tried lot of things... I've juste restart my...

BTW we agree that for a Wemos mini D1 (4M) I can only flash the 1024.bin file ?

It's really crazy... After 5 times of setting the wifi network it finally connect to my router. Then, going to the main page of the Wemos : OK, going to the device page : OK but it's sooooooooooooooo long to charge the page. Pinging it : on 4 packets, 1 is lost... Going into the edit device page : u...

Well, I can't understand what is going on with the Wemos. I compiled another light version only with Neopixel, DHT22, MH-Z19, OLED, Framed OLED and SDS011 dust sensor and flashed it. I can connect the Wemos, set the right network with the password. The countdown goes from 20s to 0s and then goes bac...

Hi everybody, Since few days, I am experiencing some issue with EspEasy on my Wemos D1 mini v2.0.0 for my new project. I used to flash espeasy R120 and I decided, for my project needs, to switch to the V2.0 Dev 9 or dev 12 depending of what I need. I used to flash with Arduino IDE 1.8.5 settled on :...

As a follow up, it is working like a charm.

I do have another problem but I'll open a new topic

I have the B sensor version with the specific white plug.

I did have CRC read error during few minutes. I guess the time to the sensor to heat up (I though it was written somewhere that 3 minutes are needed)

But waiting a few moment and the Wemos is able to read it

The last version of the source in the V2.0 branch will have a fix for this. And this will be released in dev-13. You can also build yourself from GitHub and then also choose the mega branch, which will add even more filtering options. About the ABC. If you just connected the sensor for the first ti...

Hi guys I am just having the same issue : Unstable reading, ignoring! PPM value: 715 Temp/S/U values: 21/0/0.00 I am running with v2.0.0-dev12. So I supposed that I have the B version of the sensor. Do you know if the modification has been implemented in the Dev 12 version or not ? By the way, I've ...

Thanks Domosapiens, I'll try that. I also saw your project "Stepper support request; for curtain automation <€30" that is a really good project. Thanks for your help @Grovkillen : Yes you are right. But for any reason I though that stepper motor management was a very common project... It s...

Of course Domosapiens, I saw your several posts regarding stepper motor. So, I should be more precise in my question. Well, I suppose that the A4988 stepper motor driver module is supported by espeasy with the help of the plugin made by Majklovec. (also with the help of the arduino & AccelSteppe...

Hi guys, Sorry for maybe such a stupid question but I am a little bit confused. I read many many things and I cannot figure the answer out. What would be the easiest way to manage a stepper motor (such as the famous Nema 17) with EspEasy and a Wemos D1 mini. I mean in terms of software and also the ...
