T-Relay S3 Chain in ESP Home

Misiu commented 1 year ago

T-Relay S3 supports up to 3 expansion boars to have up to 24 relays. I'd like to ask for an example with an expansion board, so it will be easier for beginners (like me) to get started.

Also, do I need additional hardware (T-U2T) to connect the board to PC? Sadly I can't find any information and I want to buy all parts that are needed at once.

@LilyGO ping :)

T-Relay S3 is based on ESP32S3 and does not require an additional downloader. I think it has already been mentioned in README that programming can be done directly by inserting USB https://github.com/xinyuan-lilygo/lilygo-t-relay/blob/main/docs/relay_esp32s3.md

The expansion board does not require special examples, only the number of relays in the sketch needs to be changed

@lewisxhe thank you for the reply, I'm not sure if I need to add another hub or should I use the same hub and use other switches. According to https://esphome.io/components/sn74hc595.html one SN74HC595 can be used with 8 pins, if you want to use more you must daisy chain them, but I don't know how to configure that in ESPHome. Guess I'll wait for the board to be available on my local amazon to be able to order it and rest everything with option to return the board if something doesn't work.

same problem here cannot find adeguate informations for configure correctly the YAML file.

Here is my working code in ESPHome. The sr_count is define how many chains is daisy chained together.

@szab0lcs thank you for sharing your code. Did you have flickering issues - https://github.com/Xinyuan-LilyGO/LilyGo-T-Relay/issues/24#issuecomment-1868701351 When you restart the device does any of the repays turn on/off? I want to use T-Relay S3 as a garage controller to control doors and read a couple of DS18B20 sensors.

Yes I have but I will try to solve that issue. If I get any solution I'll keep you posted.
