![]() ![]() 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?
