[arteck]

if the device is offline (power off) then we have no data from axios response
"false" ist not a booleon
check all possibilities in value and set to boolean (true/false) and not to string

Pull request overview

This PR attempts to fix the online state handling when a WLED device is offline by adding connected = false flag when device initialization fails. However, the PR also introduces a problematic change to how object values are serialized in the create_state function.

Changes:

• Sets connected flag to false when device initialization fails (line 1386) - this is a correct fix
• Modifies object value serialization logic to extract .val property before stringifying (line 1593) - this introduces critical bugs
• Adds changelog entry to README (missing issue reference)

README.md	Adds changelog entry for the online state fix

This change introduces two bugs:

1. When value is a state object like { val: false, ack: true } (line 1392), the code extracts value.val which is false, then calls JSON.stringify(false) which produces the STRING "false" instead of the boolean false. This corrupts the state type.

2. When value is a plain object from device data (not a state object), like at lines 956, 960, 1137, the code tries to access value.val which is undefined, then calls JSON.stringify(undefined) which returns undefined. This breaks state creation for regular device data objects.

The original code JSON.stringify(value) was correct for plain objects. If the goal is to handle state objects passed at line 1392, the fix should be at the call site (pass just false instead of { val: false, ack: true }), not in the generic create_state function. Alternatively, add proper detection: typeof value === 'object' ? (value.val !== undefined && value.ack !== undefined ? value.val : JSON.stringify(value)) : value
