Hi all!
I have Victron SmartSolar 100/30 and Smart Battery Senser installed. I also added VE.Direct connection to the SmartSolar to connect to my own systems.
However, I found that the temperature data from Smart Battery Senser isn't available. Is there a way to get it available to VE.Direct? I think it would be smart addition to the system that the SmartSolar would send that data if it's available.
Thank you!
SmartSolar can receive battery temperature (and battery voltage) from Smart Battery Sensor if you use VE.Smart Networking.
But maybe you already have this enabled?
I also added VE.Direct connection to the SmartSolar to connect to my own systems.
Connect to what, exactly?
Thanks for answering.
Yes my SmartSolar and the sensor are connected and everything works fine from Victron side.
I have my own system that reads data from the MPTT using VE.Direct protocol (text based). The problem was that the temperature data is not available there even though the sensor is connected with the MPTT.
I have now been trying to read temperature from MPTT using VE.Direct HEX protocol. However I can't get any answer.
When I tried to read value from 0xEDEC, the device doesn't respond to that but instead sends different async variables. The command I'm using is :7ECED0075
Am I understanding something wrong. Shouldn't that register contain battery temperature that MPTT receives from smart battery sensor?
Firmware is 1.59
Do you use BT to connect the two devices? Have you installed AND configured a temperature sensor on the smart shunt? Look in the App where you established the BT Network, does it say, that temperature is transmitted, do you have temperature readings in your App for the SmartShunt?
I don't use a temp sensor on my SmartBMV, instead I monitor my start battery voltage, so there is no temperature transmitted (and I don't want temperature data transmitted, as I have LiFeYPO4 batteries, they need a flat charge profile WITHOUT temperature compensation)
It may be the case, that the Ve.Direct protocol of the MPPT only transmits own data, and does not re-transmit data received from another device. So you may need to read this data via Ve.Direct from your smart shunt.
Yes those two devices are connected with bluetooth and the MPTT sees the sensor (so voltage and temperature are coming from sensor). I can see the temperature when using Victron Connect and it says that they are connected.
The sensor does not have VE.Direct port, it only operates using bluetooth. That's why it would be needed to get the temperature from MPTT, which naturally knows it as the bluetooth displays it.
