waveshare esp32-s3-poe-eth-8di-8ro-c

[krishmurali77]

Do anybody have template for waveshare esp32-s3-poe-eth-8di-8ro-c module, It uses TCA9554PWR
GPIO expansion chip to control 8 relays. i tried pca9557 but it didn't work. please somebody help me.

Try again with PCF8574

EDIT: I fear the PCF8574 won't work either considering the difference in I2C protocol. The PCA9557 comes more close but it's address range in Tasmota doesn't fit the needed 0x20 waveshare address.

EDIT2: If you can compile your own you might want to try and change below defines in file xdrv_69_pca9557.ino:

#define PCA9557_ADDR_START       0x20
#define PCA9557_ADDR_END         0x28

Make sure to disable #define USE_PCF8574 as it uses the same address range.

[arendst]

I received mine and based on that I rewrote the PCA9557 driver to also support the TCA9554. They are mutually exclusive so you'll have to #define USE_TCA9554 and NOT #define USE_PCA9557.

With this rule my relays can be controlled form the GUI:

rule3 on file#tca9554.dat do {"NAME":"TCA9554","GPIO":[224,225,226,227,228,229,230,231]} endon

BTW the ESP32-S3 template is:

{"NAME":"ESP32S3-POE-ETH-8DI-8RO","GPIO":[40,1,1,1,32,33,34,35,36,37,38,39,5600,704,672,736,5568,1,1,1,1,1,0,0,0,0,0,1376,1,1,608,640,1,1,8864,480,8800,8832],"FLAG":0,"BASE":1}

This provides support for:

• W5500 ethernet connection to be enabled with EthType 8.
• WS2812 led with SetOption37 24 for correct channel mapping.
• Buzzer with BuzzerPwm 1 like Buzzer 1,2,3,0xF54 to be used in rules. Change buzzer frequency with PwmFrequency 200.
• 8 optical isolated inputs as button1 to button8. Momentarily connecting the input to Gnd will toggle the corresponding relay.
• Boot button used to toggle the WS2812 LED.
• TF Card with at least a folder named /sd

For the RTC enable #define USE_RTC_CHIPS and #define USE_PCF85063.

If need be detach buttons from relays with command SetOption73 1.

[krishmurali77]

Thank you so much. configured and working successfully as expected.

[krishmurali77]

Detach buttons from relays with command SetOption73 1 is not working any other settings should be altered along with it please let me know so that i can use inputs for other sensors.

[arendst]

It works for me:

Notice the inputs have no direct connection to the ESP32-S3. The are optically isolated so what you see when SO73 1 is a message telling you what happenend on the input.

What other sensors do you have in mind?

[arendst]

You may need to change the template where the buttons are defined.

Replace a button with anything sensor like and report if that works for you.

[valdus2]

Can the inputs be detached from the relays? So we can have 8 digital inputs used for dry contacts for example and 8 relays which can be controlled from web gui, rules, http call etc. independent from the inputs.

And a second question, the same template works for the non POE version?

Thank you in advance.

[arendst]

Detach buttons from relays with command SetOption73 1.

I'm quite sure the same template works for the non-PoE version too as the Waveshare docs is the same for both versions AND PoE is simply a hardware addition

[valdus2]

Thank you for the info @arendst.
