Can Scheduled Charging Be Stored and Executed Locally on the Charger (Offline Mode Support)?

[Madanbot]

Question: Local Scheduled Charging Capability

I am currently using a wall-mounted EV charger branded as Timxon, model EAW-A007T, running firmware version A0-V2.1.0-beta2.

Although the charger is connected via OCPP 1.6 JSON to server through 4G LTE (Quectel EG915U), we are experiencing reliability issues in connection stability, especially during idle states.
This affects automated charging scenarios in smart home environments.

Current Behavior

• The charger disconnects from the OCPP server roughly every 60 minutes when idle (no car connected).
• Heartbeat messages are not sent when the charger is idle, leading to WebSocket closure either by the LTE modem or the server.
• We are using Home Assistant as our automation controller, which triggers RemoteStartTransaction commands at scheduled times using input_datetime.

However, if the charger is disconnected from the OCPP server at the scheduled time, the charging session does not start, and the command is lost.

❓ Main Question

Is it possible to store a scheduled charging command directly on the charger itself, so that:

• A future charging time (e.g., "Start charging at 02:00 AM") is stored inside the charger
• The charger can begin charging at that time even without active connection to the OCPP server or Home Assistant
• The schedule is retained across disconnections or reboots

If this is not currently supported, we would like to know:

• Whether this feature is being considered for future firmware versions
• If there's any local API or interface (Modbus, MQTT, direct GPIO trigger) that could be used to implement such fallback behavior

Why This Matters

• In smart energy systems, EV charging is often optimized based on electricity tariffs or solar production.
• These systems (like Home Assistant) need reliable execution of scheduled charging, even in case of temporary internet or OCPP disconnection.

Request Summary

1. Can the charger support locally stored scheduled charging?
2. Is there any workaround (e.g. trigger by external switch or time-based rule) to enable this behavior?
3. If not currently possible, is this functionality planned in future firmware updates?

We appreciate your clarification or guidance regarding offline autonomous scheduled charging support.
