Domoticz

I try to get my RFLink-WIFI to work, but this does not work.

I have configured the NodeMCU as indicated in the manual NodeMCU v4.

Because of the slightly older RFLink version I have connected the RX and TX of the coupling board via 2 wires to the RX and TX of the Arduino. I have checked that these are not wrong.

However, I do not know whether / (how) it can be further checked whether the RFLink-WIFI works properly outside Domoticz. I have doubts whether the NodeMCU communicates with the Arduino. How can I test this?

In Domoticz I can neatly add the RFLink and connect works, but it seems that it does not work properly. See log below.

This continues endlessly.

I don't see a signal coming in and can't send a signal. Is it possible to read logs from the RFLink, for example?

The RFLink's firmware is R48. Do I have to do anything to run the communication about the NodeMCU?


Are there other ideas that can help me further?

[EDIT] translated as this is an international forum

I made this config with a Wemos D1 pro On the Wemos espeasy is configured as Ser2net. Connect as described at https://www.domoticz.com/forum/viewtopi ... 20#p134655 You can do this with resistors or with logic level shifters.
