Sid Genetry Solar Posted March 29, 2021 Share Posted March 29, 2021 I was recently talking with a Genetry Solar customer, and they posed an interesting request that I'm certain will be of quite some interest to customers. I'd like to gather some ideas/interest so it's of use to as many customers as possible. (I know other inverter manufacturers specialize in telling customers what can't be done...so that's where we at Genetry differ!) Basically, when the WiFi board is connected to a WiFi hotspot or network of other sort...I would need to add a setting for a static IP address (and of course, a way to see said IP address on the screen). This way, you could easily hardcode an ESP8266/ESP32 or other WiFi-enabled device to connect to the IP address (on the same local network), and grab data directly from the WiFi board (GS inverter), without using a cloud server as a relay. For that matter, you wouldn't even need to have Internet connectivity on the WiFi hotspot. If that's all good, then there's more questions: Reading data from the inverter, what would be the best format? I'm considering something like "126.96.36.199/stats.json"--read voltages, temperatures, fan status, etc., etc.--much like what's currently available on the MQTT server possibly other files such as "188.8.131.52/scope_out.txt" for the AC output 'scope datapoints (and "scope_in.txt") for the AC input scope datapoints said files would contain a list of 200 numbers, separated by CRLFs (i.e. separate lines). or is JSON format easier to parse? (Sure is a heap more work for anything except computers with gobs of memory and a dozen abstraction layers!) Any suggestions for "commanding" the inverter? I'm currently considering an HTTP POST request to "184.108.40.206/command" with the command in the POST datastream. I still do NOT plan on opening up system config (i.e. battery setpoints, system mode, etc.) to any HTTP/WiFi access, simply for security reasons. You're welcome to provide your input/thoughts on this as well. Just polling for ideas, I suppose. Quote Link to comment Share on other sites More sharing options...
