lillygo rs485 ip

[LeroyLam]

Is there any plan to add a LilyGO integration for the battery? Currently it doesn't retrieve the battery data from the V2. The battery uses RS485 communication, so it might be possible for the LilyGO ESP to read the RS485 data and expose it to the system.

Thanks for the suggestion! 🙌

Here's how this works:

• Vote by clicking 👍 on the original post — not in the comments
• The more votes an idea gets, the higher it moves in the priority queue
• I review feature ideas periodically and implement the ones that benefit the most users

If your idea is very specific to your setup, it may not make it into the core integration — I'll try to suggest a workaround in that case.

Feel free to discuss details or alternatives below.

Hi,

How does the LilyGO connect to Home Assistant? Does it use ESPHome to expose entities directly?

Best regards

[LeroyLam]

Yes, it works via EspHome, then you can fully read it out in Home Assistance.

Unfortunately there are no plans to support this right now, I have no way of testing this unless I purchase a Lilygo. There are cheap alternatives like the Elfin EW11.

I understand that, but I have four batteries running on a Lilygo; because it uses Modbus, it can only communicate with the V3—it doesn't pick up the V2 or the first-generation model, which is why I asked. Now I'm doing it via ESPHome.

I also would like lilygo support.
For the entitie namings and action you can copy them from my bleuprint.

I also can do some testing.

The new beta which also has zendure support: i did not look how it is implemented. But if we could add other batteries with a yaml file which contains the neccesary entities and automation that would be great. I also have an Sessy battery for example.

Hi,

This will be added in the next release of Omnibattery: - LilyGo RS485 / ESPHome driver: support for Marstek batteries bridged by the marstek-lilygo-rs485 firmware — telemetry and control go through the ESPHome device's HA entities (the battery's RS485 port is occupied by the ESP32). New brand in the config flow; same register semantics as the direct Modbus driver. drivers/esphome.py.

I am pushing a new beta today in omnibattery repo (https://github.com/ffunes/omnibattery), however I am going on holidays, so if this doesn't work on the first try, you will need to wait a week before I can do any changes.
