Just live with that.Īfter a while, you will be able to make a connection, send requests and interpret responses from the device using a computer, just like the app is doing on your phone. Sometimes there are “secret” handshakes that are not aesy to understand, but that can just be sent “raw” and you don’t really need to understand what they are for. Try to remove requests you do not understand, and see if they are superfluous. Try to understand the responses you get back again.

Try to send the same things to the device that you see the app is sending from a computer with a bluetooth dongle.

Renogy BT-2 Bluetooth Module RJ45 Communication Port Wirelessly Monitor. How do you interpret them? How do you seperate them from the SOC values?ĭo you need to send anything to the device to get the SOC, or is is sent unsolicited every time it changes? 12V 100Ah LiFePO4 Deep Cycle Lithium Battery w/ Built-In Bluetooth BMS 2000. Then you have to see if there are any other packets with FE80, but with values that are clearly NOT the SOC.

Ok, now you can be pretty sure that packets starting with FE80 will contain the SOC-value, and that it is returned in 1/10 of a percent. Then, later you see that you get a packet with FE80003E3 and the app showed 99.5%, and then you find a packet with FE80003DE and the app showed 99%. You might see a packet from the device with the value like FE80003E8 and you see in your notes that this was sent just when the app updated the SOC value to 100%. Usually, it is pretty easy to get the basic stuff, like reading power values etc.įor example. Study the traffic in the dump-file, and try to understand how requests and responses are encoded and what they mean. wireshark while you note down the timestamps and what you do in the app and the values you can see in the app. I still think your best bet is to reverse engineer the protocol - or the vendor app.ĭump the traffic between the vendor app and the device to a file using e.g. So after a few days without much sun, the solar charged batteries would be empty, and the whole project caused more problems than it solved. Other times, tasker was not able to start the vendor application, or it did not wait long enough to take the screenshot if the bluetooth connection failed for some reason and the app took longer time to start up.Īnd sometimes the whole process would stop, and there was no way to restart it without travelling up there and restart the tablet.Īnd ALSO, a tablet is using much more power than you would think when running 24/7 like that. When the image was received, I pushed it through some OCR application to extract the text, and then a python script parsed the resulting text and pushed data to HA with MQTT.īut his whole process was highly unreliable, and quite often the OCR would give unexpected results which gave me the wrong values in HA.

I don’t remember the details, but I believe I used the app “Tasker” on a simple Android tablet to start the monitoring app, wait for a few seconds, and then take a screenshot, and send the screenshot either using a HTTP POST or by email (can’t remember exactly) to a server and then go back to sleep again. What options are there? I am happy with the device itself but regret the purchase due to not understanding the limitations of monitoring. My ultimate goal is to be able to monitor: What I am wondering is if I setup a dedicated tablet/phone running the Renogy app, is there a way to scrap or otherwise extract the data from the device and send to HA? Using the Renogy RS485 to USB cable on a pi.Trying Olen’s BT-1 solution (did not work).My attempts to decode the communications of the BT-2 has thus far failed and I cannot seem to wrap my head around the process so wondering if anyone else has any ideas or solutions. Whereas this is handy, it is not conducive to integrating into HA.Ī small one using a Renogy Wanderer 10A utiliing BT-1 set up (works great)Ī larger one with a Renogy 48V 3500W Inverter Charger with a communications hub and BT-2 and unable to monitor with HA Renogy only created a phone app to monitor their devices.

The Renogy DC Home App can help make your off-grid power system smarter by giving you access to configure, monitor, update, and diagnose your Renogy products from the convenience of your smart phone or tablet.Wondering if anyone can assist with my predicament.
