I'm a an owner of two of the 12k units. Also a long time user of Home Assistant, and have these things working really nicely with a smart thermostat using external room temp sensors. As we all know the internal sensor is... wanting. The thermostat implements it's own automatic heat/cool mode...

Use the app to override the BMS low cutoff voltages temporarily.

You're asking about a few different components, each of them requiring a different solution. The MPPsolar is something I don't have much familiarity with. I use a Growatt, which is as far as I know same thing under the hood. But I think the communication protocols are different - I don't know...

This is the mfgr's website, which wasn't even available last week. https://www.tumblevd.com/index.php?route=product/product&path=50&product_id=55 You can also write and ask when amazon is expected to have stock back service@tumblevd.com they seem to be quite responsive.

The new App version does indeed come with a new firmware, loaded locally from your device on first connection. Nothing new feature wise, as the changelog said.

I wrote the mfgr (apparently). this is the response I received Hello Cory, Thank you for your consultation. We have not yet developed the function of this UART, but we are planning to develop it. We will develop this series of products later, and this UART port can come in handy. Regards

Yup.. I've got some debugging to do (bought one to test out). of course i'd rather BTLE the data, but if i have to the UART port should work. I'll try it out with the RS2XX to USB dongle I've got to see what it says and go from there. After that I'll work on the bluetooth and see if i can make a...

Can you send me the user manual if it came with a link, or some readable photos? I'm trying to figure out how the port on the front > left works and If it can be used to export the data it collects in realtime

Do you have the IoT infrastructure to try out the UART port/data collection? I really want to get data into influx. I know that is MY interest, but for this price, I can't even make a decent V/A/Watt monitor with an ESP8266/ina226/shunt from scratch.

yup, can confirm. It is self calibrating once it reaches full charge. Even worse, whenever you change settings on the BMS App it will reset SOC to that incorrect value. While I kinda understand if you change capacity settings, i wish that for other settings SOC was stored in memory.

In the naming department, Junctek wins. honestly how much worse could that get? I think the TBD is going straight for victron though. It couldn't be any more blatant - Both named SmartShunt, nearly identical design, UART.Connect vs VE.Direct... I wouldn't be surprised if this IS the victron...

actually, it stands for Totally Badass, Dude

I thought that too.. but then downloaded the app and there is a whole line of TBD 'Smart' things. so ¯\_(ツ)_/¯ currently hovering on Add To Cart..

https://www.amazon.com/dp/B09KNJ4Y7B/ref=cm_sw_em_r_mt_dp_SE6SFF695SZTDPSBE0CA This thing looks inexpensively interesting. Anyone tried it out? I'm not too interested if there is no way to get the data out, but that UART port looks promising. Sure looks oddly similar to an identically named...

I believe that is the information that was used already in constructing Grott
