Based on the specs from the original link, it looks like your BMS has both CAN and RS485 communication ports. Have you tinkered with those at all?
You have to pay extra for those capabilities. I have not done anything with CAN or RS485.Based on the specs from the original link, it looks like your BMS has both CAN and RS485 communication ports. Have you tinkered with those at all?
OUTSTANDING!!! I imagine it will take days, if not weeks, for those vendors to get back to me on this, so you just cut a bit chunk of time out of my decision making process.I've attached the protocol to this post.
As far as I know they come with the capability built in, you just need an adapter to USB or whatever you want to hook it up to.
Am I understanding it correctly, I must disassemble the case to access the port? I do not have any more external ports visible, the temp probes take up the last slot.If you see check my post a few posts up, you can see the BMS has an RS-485 option and the protocol is available. I'm working on integrating it with Grafana, but you could use it to implement anything you want. Grafana also allows email alerts etc. A plus point is that you don't have to rely on a (sometimes flaky) Bluetooth connection.
Only pic I have on me.
Mine looks like this. There are two ports below the sensor connections. This is a Heltec 200 amp with 2 amp active balance.Should be the same. Check it out when you have time.
There are RS485 to USB cables available on Amazon if your looking to use a PC.Yep that looks like mine, so I'd say I'll have the ports too.
Can we buy the 485 cable or do we need to make one up?
Is the work above using Grafana the only work being done on working with RS485 on this BMS?
Watch Power (MPP Inverters) has a desktop and a phone App for example.
