Thanks, yeah I don’t know enough about these issues to know what’s what.
In the end it seems to have connected. I have wifi repeaters (supplied by the ISP router supplier) so I guess they are using different channels and maybe some conflicts.
Thanks!
I had a look and it seems D7 is the same as GPIO13 (I had earlier tried GPIO7 thinking it might be wanted ot use GPIO instead of D). So I replaced D7 in the code with GPIO13 and revalidated. That error has now been resolved but the validation threw up a new error, so now need to track that one down.
This is the new error:
INFO Reading configuration /config/esphome/esphome-web-82e879.yaml...

I’ll look a bit more and see what I can work out for these.
I’m sure it’s painful reading my stream of ignorance!
This just seems a promising option for getting my Smart Shunt data into HA, and it is important data to me, many of my energy system automations rely on it. I get it now via an alternative but that prevents me from accessing other battery data. So I am hoping I can crack this nut, but I need some guidance.
Found the error, those two sensors were defined twice in the code I pasted in. Removed the duplicates and
INFO Reading configuration /config/esphome/esphome-web-82e879.yaml...
INFO Configuration is valid!
Yay!
Installed and got this message at the end:
INFO Successfully compiled program.

So it looks like success. Now to work on the wiring of the ESPboard to the Shunt.
Thanks all for your patience. I’m learning a lot.
Will report back once I have had a suitable opportunity for connecting the wires.
As @pepe59 said you need the underscore. This was caused by an esphome update. Where uart0 worked before you now need uart_0. I think it’s important people know why this is now the issue
Getting the data passively via Bluetooth is now possible!
It takes a little extra effort to get the Advertising Key so HA can decrypt the data, but otherwise it’s quite seamless; once you add the custom integration and restart it was even auto-discovered! I spent a while trying to get said key off of my android phone but finally gave up and went the Linux route mentioned in the Reddit post.
If the Linux bit is just too much for you, I ran across some posts (I think they might have been official Victron ones?) that mentioned they are working to make the advertising key accessible from within the app. They were relatively recent posts (earlier this year), so I’m hopeful that comes to fruition. That would make this whole process INCREDIBLY simple and straight-forward.
Here’s a screenshot of everything it’s pulling in:
That is amazing. Victron, while loving open source, has always been tight lipped about their Bluetooth. This gets the door cracked and hopefully swung fully open soon!
Does anyone have a full guide on hooking a ESP32 (D1 R32) up to a Victron SmartSolar 75/15 and get it working in ESPHOME? I have searched around and am confused as I see some of the MPPT units pinouts read 1,2,3,4 from left to right and others read 4,3,2,1 from left to right? I need to know for my model smartsolar 75/15 what pins I should use to connect to which pins on my ESP32.
Also I have a jumper connected to the two middle pins on my VE direct port. Can I just remove this jumper permanently?
The part on Github that confuses me is it shows pin 2 from the right as TX but then they are not stating for which model. But then below the schematic they say TX is pin 3, so which is it?
It’s always pin 2 on the socket. It’s pin3 on the jack (plug) as it’s inverted (industry standard). You don’t need the ground pin at the end. So as long as you don’t use either of the end 2 pin connections you can’t blow anything up. If you don’t receive data to the esp then just use the alternative middle pin.
Got it working but using an ESP8266 on TX pin from controller to D7 on ESP. I am seeing a lot of errors though and the Battery voltage would change constantly from say 14.6V to 1.06 and then back to 14.6V. I tried using throttle 30s instead of 10 but it does not make much of a difference.
