Released again: Get a nice dashboard for your grid-tie inverter or pure sine inverter for almost peanuts.

Unfortunately I have to recall that tutorial for most devices on the market.

Tasmota has a HUGE security flaw on ESP8266 based devices: it cannot handle an encrypted MQTT messaging and runnin unencrypted makes it ridiculouly easy to hijack the device into a malware bot.

But some devices, preflashed with Tasmota, are ESP32 based and these can use TLS-encrypted MQTT.

Get a cheap "tasmota-enabled" ESP32 based smart-plug.
e.g. https://de.aliexpress.com/item/1005006078553282.html
We will pimp it with some configurable dashboard, for free...

Just follow the instructions here: https://github.com/arendst/Tasmota/discussions/22060
Just replace the port 1883 with 8883.
Replacing the port 1883 with 8883 on common ESP8266 based smart plug will not work !

Works cross-vendors, nothing to screw, nothing to solder, no programming required...

You get a nice dashboard like that one:


Enjoy !

I am not following how the smart plug is wired. Do you put it between the inverter and the grid?

Yes, exactly.
As long as your grid-tie inverter does not exceed 3kW 220V (the max that a regular plug can handle. it is just plug and play.

But you can also put the plug to monitor a power consumer like a fridge, or a heat pump.

I have "Tasmotized" a couple of Sonoff S31 WiFi smart plugs (they are only about $10 each!) I already have a local MQTT broker and Grafana though so I don't do the cloud thing. Super handy and I can still turn them on & off via their local web interface.

Nice too, but you need a local computer running all the time, had to configure Grafana, the database and match a LOT of stuff until you got -locally- your dashboard. The described solution needs nothing from that, is set up in a breeze and the dashboards are accessible worldwide.

I run a tiny Odroid server that uses a few watts, home assistant, emporia vue with some emporia smart plugs here and there. I think I have 37 devices but I haven't added them up in awhile. I tried flashing some no name smart plugs to Tasmota but eventually they got out of date and hosed up in firmware hell. Now, I use only Emporia or Shelly devices on Home assistant. Good luck with Tasmota...
