    HELLO :) We are already running on Espcode, that can pull/change modbus on solar inverters(mostly growatt) We need to expand this code, and make it able to take energy (Spot prices) into relation. We use ESP32 1. Be better grapchal looking (Web interface) 2. Access to the ...able to choose between DK1 or DK2 (This is price regions in denmark) (Also we need to expand to other countries later on) 4. Add tax/vat/tarifs 5. Code needs to be stand alone, meaning it should be able to run without home assistant, but also should be compatible with home assistant. 5. Allow Simple automations, like: Stop exporting electricity if spot price falls below X. or like Start charing battery if prices go lower than X Potentially we i will need you to work with us on this project, and do all futur...

    ...5000mAh LiPo battery. To ensure safe and efficient charging of the LiPo battery, we require a skilled electronic engineer (if you've already worked on similiar project) to create a LiPo charger circuit with comprehensive protection features, including low and high voltage charging protection. I've tried with TP4056 but the charging time is too big. **Key Features:** 1. Overvoltage protection to prevent damage to the battery during charging. 2. Overcurrent protection to safeguard against excessive current flow. 3. Low voltage charging protection to prevent the battery from reaching dangerously low levels. 4. Charging status indication for the microcontroller **Key Responsibilities:** 1. Design a Li...
