Hi!

I think all initial problems were solved so I'll close this topic.

If there any other problem please create a new topic.

Best regards.

1 - Replace PCF8575 library because digitalRead function doesn't works in SkyWodd's library.

Hi!

Try revert this changes:

1 - Reconnect to MQTT broker after every dosage because delay used in dosage functions breaks the MQTT connection.

RTC done Glad to hear! One uln2083APG chip is also damaged. It's strange because the IC is not connected to 5 or 12 V. But you can just buy and replace there's no firmware. It's a transistor array. Sorry for all questions. No problem friend. How can i PAy for the webpanel? Via Paypal the address is...

Hi!

The connection should be:

+ to 5V
- to GND
D (SDA) to 20
C (SCL) to 21

Best regards.

Yes, it's suitable.



You should test every part using test codes.

So you can replace the IC DS1307 or buy a separated RTC module and connect to the board after remove jumpers. -------------------------------- Last edited Thu Apr 25, 2019 4:21 pm -------------------------------- To avoid problems with relay board wiring I recommend buy my relay board .

Can you show me how this relay board is connected? Are you using separated 12 V power supply for relay board? -------------------------------- Last edited Thu Apr 25, 2019 4:02 pm -------------------------------- Check if RTC can be found at 0x68 when the battery is connected. #include <Wire.h> void...

Can be but first check with a new battery and test code.

Always check the baud rate on setup. Serial.begin(9600); Set the baud rate on serial monitor to 9600. Anyway I think your RTC it working fine because it sent right data days ago. I think the problem is related to overheat. When the regulator heat up the voltage drop and RTC stops working. What's the...

Try fix the time using monitor serial with this example: #include <Wire.h> #define Binary 0 #define Hex 1 /******************************************************************************* Function Prototype *******************************************************************************/ unsigned int ...

Hi! Welcome Marco! Glad to know that I have helped you. I think you are talking about RTC battery. On MQTT broker I can see that your RTC is not working fine. Have you placed the jumpers in right position as explained here ? This is a new battery? Also to use 12V power supply you should install a fa...

Thank you!

The voltage should be around 1.5 V with ULN connected.

Disconnect the ULN and measure the voltage. It should be 5V.

Maybe the input voltage on PCF is less than 5V.

Hi Jean!

Some users has problems with this PCF module. Can you show us the schematic of your board?

You had some problem with your relay board as relay not being activated just the LED light up slightly?

Best regards.

Hi!

Do you have this PCF module working with your relay board?

Can you show us some pics?

Best regards.

Hi!

If do you have problem yet can you answer my last question?

I thought the problem was solved.

Best regards.

Hi!

Can you show me some pics?

Best regards.

Hi!

Welcome Roch!

Gio, the problem was solved?

Have you tested with new module?

Best regards.
