predictive selling optimizer

[dannyverk-byte]

Area of the proposal

Energy management or control strategy

What problem would this solve?

It will be more cost efficient

Proposed solution

Buy energy at low prices, and sell at high prices

Example use case

Hi ffunes,

I'm building a small external economic optimizer for Omnibattery v1.4.0, while keeping Omnibattery as the sole battery controller and Modbus client.

The goal is to optimize charging, self-consumption and deliberate grid export using quarter-hour import/export prices, solar and consumption forecasts, battery efficiency, degradation cost and a persistent energy cost basis. Export would only be allowed when expected net profit exceeds €0.20 per delivered kWh.

I would prefer to keep all normal PD, predictive charging and safety functionality inside Omnibattery, and only temporarily hand over control for profitable trading actions.

What is the recommended supported interface for this? Is there a runtime service or entity-based way to request a temporary fixed charge/discharge power with SOC limits, and then safely return control to the normal automatic mode? Would manual-power slots be the intended approach, or is an external optimizer API planned?

I would also be interested in whether native positive-price arbitrage and deliberate export are on the roadmap. I'd much rather extend or integrate with Omnibattery than build a competing battery controller.

Thanks!

Who would benefit from this?

Most Omnibattery users

Alternatives or workarounds

It's a new feature. An alternative is also possible, but what would that be?

Confirmations

• I searched existing discussions and did not find the same proposal.
• This is a general feature idea, not a request to support a new battery brand or model.
• I understand that community interest and technical feasibility influence prioritization, and that no delivery date is guaranteed.
• I removed passwords, tokens, API keys, complete serial numbers, IP addresses, and other sensitive information.

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.

One easy way to steer the mechanism is by changing omnibattery's pd target. Want 100W exported? Set the pd target to -100. Want the battery to charge at 500W? Set the pd target to +500. All the normal safety features will still apply.

As long as exporting to grid can be optional you have my vote. (B.t.w. The voting mechanism doesn't say you can't vote for your own request, so please do add your 👍 too)
