Is there such a thing as a ve-direct splitter, or can I just intercept & tap into ve-direct wires for data. Would this slow the data stream down. Basically I want the ve-direct out of the smartshunt to go to my control system AND a cerbo-gx, both to be able to display the data at the same time.
I have a system that runs a cerbo gx for remote monitoring but my standalone control system I’ve built in my van can also read & display data to my 2 control screens from the ve-direct on a smartshunt for data.
Would the 2 reading devices need to be isolated from one another?
its an Serial ttl connection you can split the connection but its not how serial works i can come to problems and the cerbo is sending and receive so ist an bidiretional comunication when the second system do the same the data crashes didnt know about your second system but cant you use mqtt from the cerbo to use the data on the second system ?
Thanks for your input. Not sure I can use MQTT on the system I have built but I will take a look & see what’s possible. I’m using a 4D Systems touch screen & multiple Aruino/Teensys for I/O control so haven’t played to see if I can get both systems to play nicely
As mentioned above, it is serial TTL : if you use this you should also use a digital isolating device.
The output can probably drive 2 or more loads, so 2 or 3 devices reading the data is ok. However, the receive side of serial TTL has no arbitration, so only one external device can send to the MPPT.
Right, think I can use MQTT so had a first play today. I can access all data using MQTT Explorer & see all topics etc when local to my Cerbo but want to take it one step further & access it remotely.
I have managed to set the login & it logs in just fine with encryption & validate to port 8883 on the victron MQTT server, it says connected but I don’t get any topics or data through, it just sits logged in but empty?
Don’t suppose you would have any ideas, or do you think I am better off starting a new discussion? I’ve done numerous searches (maybe for the wrong wording, I am very new to MQTT lol) but cannot find anything relevant.
