RFQ Details

I'm reaching out to you because I'm interested in purchasing SmartHome devices for my company, specifically a set of: 1. Touchable small LCD screen (bluetooth) 2. Customised Raspberry terminals 3. Smart Lock 4. Keypad waterproof wireless 5. Contact window sensors 6. Movement sensor I'm attaching some examples of what I'm looking for, but everything I find on Retail markets is already programmed for Tuya or TTLOC, and I need it to work with my own API and system so it has to be opensource. Would you be able to help us? Thank you in advance. Regards, Roberto
