I had an excellent experience with JustCare. Mr. Bilal and Mr. Hamid provided exceptionally professional, courteous, and kind service throughout the entire process. They were knowledgeable, punctual, and ensured that the smart door lock was installed properly and explained clearly.

Their attention to detail and commitment to customer satisfaction were truly impressive. I highly recommend JustCare, particularly Mr. Bilal and Mr. Hamid, for any services related to smart door locks. Thank you for the outstanding service!

Bilal and Hamid came to install my new smart lock on short notice today. They were excellent and the price was fair. Hamid did a clean job with the handy work and Bilal was very thorough and helpful with the set up and teaching me about the lock. They cleaned up before leaving too. Very satisfied. Thanks team

    Upgrade your Daikin Multi-Split HVAC system with the Dropair DK-S21 Adapter, a reliable interface for connecting your indoor unit’s S21 port to any 24V smart thermostat. Whether you use Nest, Ecobee, Honeywell, or other smart systems, this adapter bridges the compatibility gap for full control.

    This solution is compatible with Daikin indoor models like CTX, FDX, FVX, FFQ, and FTX, which use a 4-wire controller such as BRC944C1. The DK-S21 adapter connects directly to the S21 socket on the indoor unit’s PCB – the same point used by the original wired Daikin remote. To enable smart control, the Daikin remote must be unplugged or moved.

    With Dropair’s plug-and-play architecture and Mini6S interface, installation is quick, stable, and doesn’t void your system warranty.
