MQTT Shunt discovery, input SOC to Deye inverter????

Hi all,

I found the following shunt which connects up to wifi and can send MQTT data.


I have the 8kw deye hybrid inverter which has several functions for BMS connection. Is there a simple, elegant way I can have this MQTT data tell the inverter the SOC of the battery. I don't believe the jbdbms is as accurate as the shunt and I don't know of any native way to connect it.

Thanks!
 
Hi,

I was wondering if you have found your solution already. I am in the same situation. I received my Deye SUN-8K-SG04LP3-EU last week and I am gathering all parts for my DIY 48 Battery project. As I read the documentation for the MK75 Battery Monitor, I see it is suitable for voltages up to 40V, so I don't think this Battery monitor will fit our needs.

Curious if you've found a solution in the meantime.

I have placed an order on this MM75 and am very excited about testing it when it arrives in September. I am also wondering a little bit why there are no competing products for this? Seems like such an obvious problem
 
My viltron smartshunt data is polled by ESPHome and sends it to MQTT server as well. I trust victron and it works very well.

Hello there, please note that Mkove now (posted 24 June already) also have a high voltage version available, see this news:

Had it in use now for about 2d and it seems to work well

How do you interface this with your smart home?
I'm not sure how to use the mqtt data to get to inverter or trigger smart home automations?
 
I don’t trigger any smart home automations. I just collect all this data and graph it via grafana. I’m a noob at using home assistant.
