Waveshare POE TCP Modbus Relay coil control with interval time

[Pieres]

Hi,

I have a question related to this topic:

Help with Waveshare POE TCP Modbus Relay configuration

I have a Waveshare 8-channel Modbus POE ETH Relay and I’m really struggling with getting it integrated into Home Assistant. I know the IP address is correct and the port is what I see in the web UI. I have been able to connect in python directly using pymodbus TCP client, but I can’t get the relays to toggle on\off using HA or in the Python REPL with pymodbus. This is my test config using relay 8. modbus: - name: waveshare_relay type: tcp host: 192.168.0.107 # Replace with your dev…

I have the same board and with the info of the above topic I am able to make it work.

But when I look to the manual of waveshare I see it shold be possible to control a relay so it flashes with a interval time which you can define. For example a on flash during 0,7seconds or 0,5 seconds.

See here: https://www.waveshare.com/wiki/Modbus_POE_ETH_Relay_(B)#Relay_Flash_ON.2FOFF_Command

But how do I translate that command in my .yaml file please?

For example for CH1 to flash on for 700ms: 01 05 02 00 00 07 8D B0

How do I give in the .yaml file to adres 512 the interval time 00 07 please?
To flash on immediately it is:

• name: rele’ 1 flash on
  slave: 1
  address: 512
  write_type: coil

Anyone who tried this already?
