I'm using 3 USBs on an RPi 3+ with a 2amp feed
The device was showing as off thats why I thought it was a comms prob. 2 way comms is enabled. I didn't have time to hard wire everything in and plugged into a cigarette power adapter and that may be an issue also. Will be doing a hard wire later and try the other things. If all fails I will try the different USB adapter cable.Not sure I can be of much help, I didn't deliberately buy the HX version, I just plugged the cables in and booted up the RPI. Looking at the MPPT the only setting I can see that would effect matters is the RX TX settings but why would they have been changed from their defaults anyways. I'm still on an earlier version of Venus OS 2.72. Do the devices appear in the device list on the remote console, is VRM online portal two-way communication enabled?. I assume Venus OS will log events so you should be able to tell whether the PL2302' are active- don't ask me how but presumably accessible via ssh. The PL2302 do require some power but I'm using 3 USBs on an RPi 3+ with a 2amp feed
I managed to get it to communicate with an ESP board without many issues (running ESPHome to Home Assistant).
Comms issue thenYour seeing your Pi because it communicating with the VRM portal via your WiFi, but your Pi is not seeing your MPPT data.
Hopefully the different usb to serial cable I have on order will sort it out. Watch this spaceYes, between the MPPT and the Pi.
About 10-12w, that’s including the router directly to 12v feed. A tad under a amp.What current draw would you expect from all this monitoring capability?

Any luck yet?Hopefully the different usb to serial cable I have on order will sort it out. Watch this space
No, the new usb to serial adapter lead only came today, I will give it another go sometime in the next few days and let you know.Any luck yet?
Just got back from trying the PL2303TA lead and all good, so either the PL2303HX chip is not supported or my one was duff.
Anyway all good now and many thanks for all the help.
Yes, well spotted, the 1st one that didn't work was the PL2303 TA due to either not being supported by the Venus OS or duff, the second one the TA2303 HX worked. Sorry for the confusion.Was that not the other way around?
I was not trying to be cocky or trip you up, I was just concerned that if somebody was reading through the thread for information, that it might have caused some confusion.Yes, well spotted, the 1st one that didn't work was the PL2303 TA due to either not being supported by the Venus OS or duff, the second one the TA2303 HX worked.
