12 months ago Hello @SimonRichards,
First of all, I need to apologize for lead time to answer you. I didn't received any notification from GitHub, so I missed it. Anyway, I will try to support you us best as possible, from now on. Even if currently this project isn't plugged full time to the stove yet. So I can't confirm that everything is working correctly at any time.
Unfortunately all of the messages sent and received between the device and the stove (that I can see in the _tx and _rx topics) are all just ff_ff_ff_ff.
This is something I already faced with, and I need to reinstall it on the bench to check this point. I will update your opened issue once (not this week) I will have answer to bring on the table.
I was wondering about the difference between the two ports on my stove (and maybe yours?), they are both 4 pins and both supply 5V. One is called serial and the other remote
I worked on the port called remote. And yes, it does deactivate the connection with remote once you plug the board. In fact, during the development I plugged the remote to the stove and made a derivation to listen the communication, then I copied it to this project. I don't know what is happening on the other port (voltage, communication, ...)
what is the purpose of the "serial" port
This other port is to plug external device to have a remote connection using the Ravelli Smart WiFi. My wife manage to have it installed (free of charge), that's why I'm not really anymore using this project. But this Ravelli equipment can't do as much as the remote. One day, I will take time to listen the communication too ;-)
Hi, I have a Ravelli Dual 7 but I see from your comments that the model should not matter much. I would appreciate any help in getting this working. I have built the circuit around a nodemcu 1.0 (v3) according to your circuit diagram. It's a bit messy but I hope it is accurate. When I plug the board into the "remote" port on the stove it receives 5V, connects to my wifi and happily communicates with my mqtt broker. Unfortunately all of the messages sent and received between the device and the stove (that I can see in the _tx and _rx topics) are all just ff_ff_ff_ff. I assume this means that there is an issue with the voltage or frequency of the serial comms, however I am not equipped with the tools or skills to fix this so I was hoping you would have some pointers.
I was wondering about the difference between the two ports on my stove (and maybe yours?), they are both 4 pins and both supply 5V. One is called serial and the other remote. The plug you specified fits into the port labelled remote, I can also plug my RF remote into this port with its supplied cable and it can control the stove this way, instead of via rf. However when I power my board on this port, even without touching the serial pin, the RF remote loses access to the stove.
If the "remote" port is the correct port for me to be using, what is the purpose of the "serial" port, would it be possible to move the device over to that? Even if I could get this working I would hate to lose the functionality of the remote and depend entirely on mqtt messages.
Thanks in advance.
