Home Assistant and Twiz O'Meter is great !

Hi!

First of all, I would like to send a big thanks to Fabio for a great product!

I would also like to share my setup. Many people use Home Assistant and Node-Red for home automation, and I do as well! I got my Twizy a month ago and the TwizOmeter last Friday, so this is just the beginning. My setup consists of a Nuc running Proxmox, with an LXC container hosting several Docker containers. I'm using Home Assistant for presentation and data collection, and Node-Red for automations, with Mosquitto for MQTT communication. I have solar cells on my house, so automation helps me make the most of the sun for my own usage.

For the Twizy, I'm using a Shelly Plug S.

In Home Assistant, I have several components:

1. A main switch to turn on charging for the Twizy (Shelly).
2. A switch for "Twizy_sun." When this switch is on, the Twizy will charge when the sun produces enough energy for both the house and the Twizy (2 kW).
3. A timer switch that starts the charger at a specified time.
4. A "Twizy charge stop %" setting, which turns off charging when a specific percentage is reached.
On the Data page, I present a lot of valuable information from the TwizOmeter.

The TwizOmeter connects to a separate Mosquitto instance exclusively for the TwizOmeter, with ports open both locally and to the internet(I dont want my main Mosquitto container to be reachable from internet).
I've also set up a bridge between the (Twizy) Mosquitto and my (Home Assistant) Mosquitto, so all data from selected topics replicates to my main Mosquitto server.
With this setup, I'm able to get all the data even when driving, if I'm using wifi hotspot from my phone.
Im going to populate all value of intrest to a Graphana server for long time graphs.

Anyone else how is using Home Assistant etc with there Twizy ?

Thanks

Hi,
Thanks for the positive feedback you've just published, I appreciated it really much.
First of all I want to spend some words on your setup, which I think is very well done.
I love the way you used ToM data and how you visualize them, the idea of storing them and then using for mailing long time graphs Is really cool.
If I'm not wrong maikt created a similar system too, which is amazing as well.
In addition I want to mention that knowing ToM is now on another embedded green energy domotic house, makes me really proud of all the improvements and work done on this project.
Last but not least, I'm happy because the first ToM finally reached Sweden!

The only missing feature for now is the ability to use mqtt to control the current of the charger on the twizy ..

Receiving commands via mqtt is a task in my plans. This is the reason you find a "topic in" in ToM settings.
Sooner or later the time will come also for this task.
