ReefRhythm - Advance Stepper Motor Controller with OpenSource

[HarrisonYu]

What an awesome project! Thank you so much sharing your knowledge.

Hello.
Remind me.. should the dispenser work when it does not have WiFi?

The fact is that when the lights in the house are turned off, the Internet also disappears.
I connect the dispenser to backup power, but without the Internet, but it does not perform scheduled dosing events (

Does not go to the local page of the dispenser through the mobile Internet, does not have a connection(

Big thankyou for this project. I'm about half way though a build.

Nearly got my build complete, just adding the final touches.

After calibration I dosed 100mls in 1800 seconds (30mins). My jug is 150g, and its exactly 250g total after dosing, spot on 100mls!

I redid the housing in FreeCAD to house the barrel jack on my 12v-3.3v converter.

Many thanks again for such an awesome project.

Side question, has anyone replaced the hosing within the doser? What did you use? I'm having trouble determining what to use, inside diameter and outside diameter.

Hi, do you have added the tmc2209 support? Because I have at home this driver and a stepper motor and want to try this project

Hi everyone.
I think before MQTT in v0.8, I'll roll out a few minor updates with support for some optional but necessary things:
1) Working in AP and WiFi mode simultaneously. Accordingly, if you need to switch the controller to another Wi-fi network, it will be possible to do it without a computer.
Currently you need to connect it to PC and edit config/wifi.json in soft like Thronny.
There is a platform limitation here: when WiFi and AP simultaneously works, the DHCP server does not work on AP, so you need to set IP manually.
2) Work in AP-only mode.

3) It follows from point 2 that it is necessary to take some time for the work of the schedule. This is mandatory. Now the work on the schedule is not even turned on until the time is synchronized in obvious reason.
4) I will try to support the Captive Portal feature so that when initializing and connecting to the AP, there is an automatic opening of the page of the controller.


Therefore, I will add support the RTC module for offline work.
I have a DS3231 module, so I think about it and add it.
I think the device will automatically pick up whether it is connected or not, so its will be an option to set time from UI.

I will also add some settings:
1) Analog control work period: 15/30/60/120 sec.
2)Setting the working currents of the motors. For 23mm, for example, it is optimal 1A, 30mm -1.2A, and 40mm -1.5A. The driver itself can go up to 3A.
Now there is a hard-coded 1A.

Юрий, добрый день!
Не могли бы Вы реализовать режим точки доступа с использованием модуля часов DS3231?
Смысл этого в том, что иногда интернет может отключаться на продолжительное время, и тогда дозирование становиться невозможным.
И очень желательно реализовать одновременную работу режима точки доступа и режима подключения к роутеру, ну т.е. чтобы была возможность подключиться к дозеру напрямую, если вдруг с роутером возникнут неполадки.

Как вариант, можем рассмотреть оплату этой доработки )
