@jasonacox any suggestions? Thanks

Hi @reli3 - I made quite a few edits and accepted a few PRs (#1 and #2) that I need to submit as PRs here too. For now, I suggest you try this version: https://github.com/jasonacox/powerwall_monitor

I suspect the error is related to the pypowerwall section in powerwall.yml:

    pypowerwall:
        image: jasonacox/pypowerwall:latest
        container_name: pypowerwall
        hostname: pypowerwall
        restart: always
        ports:
            - target: 8675
              published: 8675
              mode: host
        environment:
            PW_PASSWORD: "password"
            PW_EMAIL: "[email protected]"
            PW_HOST: "192.168.91.1"
            PW_TIMEZONE: "America/Los_Angeles"
            PW_DEBUG: "yes"

Or it is in the telegraf.conf inputs section:

[[inputs.http]]
	urls = [
		"http://pypowerwall:8675/aggregates",
		"http://pypowerwall:8675/soe",
		"http://pypowerwall:8675/strings"
	]
	method = "GET"
	insecure_skip_verify = true
	timeout = "4s"
	data_format = "json"

@jasonacox this is amazing thank you for the update its now working.
Is it possible to have a dashboard to show the Connected:True or false?

I am running your string python manually would love to see this in a dashboard since sometimes my strings are offline and I have to go reboot the powerwall+ inverters 👎

{
"A": {
"Connected": true,
"Current": 0.02,
"Power": 0.0,
"State": "PV_Disabled",
"Voltage": 5.5
},

Hi @reli3 - that's a great idea. Telegraf will filter out non-numeric data points so we need to figure out a way to get it to record the true/false or translate it to 1/0. I'll see what I can do... Alternatively, you could craft a script to poll the /strings API from pypowerwall and text you when it sees a Connected: false event.

Also, I wonder why your strings are failing. Have you opened the issue with Tesla?
