I threw the black box in a drawer and wired up the SE to ethernet. I only care about SE getting monitoring data. Tesla app still shows solar production since I have a TEG/GW2.
Thats what I did too. My SE inverter is hardwired to wifi. But yesterday I got a text and email saying my Tesla solar guard gateway isn't feeding data back to Tesla. My Tesla app and SE app all work fine and shows production normal. But I want to clear up this annoying text/email from Tesla. I still see NO SIGNAL on my zigbee gateway :-(
