Fixed
- CX5120 heaters with firmware 0.4.9 never answer the observation renewal, so the 60 s
renewal of philips-airctrl turned into a reconnect and a display nudge every minute (a
beep each time) until the device's CoAP stack stalled. Push-only models now renew the
observation only at the nudge watchdog interval (30 min). - CX5120 swing now writes 17222, which the device accepts (it then reports 17920), instead of
17242 fromOSCILLATION_MAP2, which it ignores. - Repeated reconnect failures no longer spam the Home Assistant log with aiocoap task
exceptions. philips-airctrl 1.5.0 tears each CoAP context down once, even when reconnect
and unload overlap or a caller times out (#198).
