@tweethue The cieling light was a gift about 5 years ago, so actually no I don't. But taking in account this period there is no question of guarantee anymore, so that's my reason to look for a spare part.
@tweethue Hi there Hue team. Any possibility to find replacement parts? The LED driver of my Hue Still ceiling light died ☹️
@PostNL Ja maar helaas nog geen antwoord (loopt ook achter). Vervelend, zijn nl. cadeaus voor moederdag...
@PostNL ik begrijp dat jullie het extreem druk hebben, maar kunnen jullie iets zeggen over de status van 3SDMFQ9752201? Volgens verzender op 4 mei aangeboden, maar volgens T&T nog niet door jullie in ontvangst genomen. Na aantal x bezorgtijd uitgesteld inmiddels "nog niet bekend"
@PostNL Goedemorgen, kunnen jullie controleren wat er met UC561106437MY aan de hand is? Vorige week dinsdag is er een afleverpoging geweest zonder succes, echter woensdag niet meer, vervolgens donderdag zelf aflevermoment gewijzigd naar vrijdag, sindsdien "Shipment not processed"
@nestsupport_nl ik mis echt een "morgen als zondag" functie op jullie thermostaat in zo'n vakantie periode als deze...

@PyroBatNL Een molton kussensloop. Voor je kussen ja. Die kan je vaak wassen zonder je kussen daarmee om zeep te helpen. Hier Auping btw. Erg tevreden.
Fortnite is impressive, but it’s absolutely dwarfed by the world’s largest video game, LinkedIn, played exclusively by 40-50 year old white guys who compete by sending random connection requests in a quest to build the furthest-reaching “professional network.”
