Families can't tell whether an older relative's pills are safe, spaced right, or mixed with medicine they bought on their own
A man found that an older relative in his care, who has stage 3B kidney disease, had bought three medicines from a nearby pharmacist without mentioning the kidney problem, and only noticed pills lying on the table. He asked Pantip in the evening because he had no time to go back, then stopped the medicine until a hospital visit next day. Another caregiver asked if a four-times-a-day antibiotic still works when poor appetite pushes doses 1 to 3 hours apart, and got answers of 'at least 4' and '4 to 6 hours'. Both are sorting it out on a forum at night.

5 ways to tackle it
Camera and vision
Pill Packet Reader: photograph every bag and box and get one clear daily schedule
The family photographs each medicine bag and box on the table. Claude vision reads names and doses, builds one day schedule in big Thai type, and flags two products with the same ingredient or a drug that a listed kidney condition may rule out, with a note to ask the pharmacist.
Build with Claude vision, Thai drug name list, PDF print
Hardware and sensors
Pill Box Light: a pill box that lights the right slot and texts if it stays shut
An ESP32 pill box lights the slot for the current time with an LED and a small buzzer. A reed switch notices when the lid was opened, and if it wasn't by an hour later, the family gets a text, so nobody guesses at the table at night.
Build with ESP32, WS2812 LEDs, reed switch, buzzer, SMS or Telegram
Web portal
Pharmacy Card: a wallet card with conditions, allergies and medicines
The family fills a short form and prints a card for the elder's wallet: conditions (like kidney stage 3B), allergies and the current medicine list, with a QR to the live version. The pharmacist can read it before selling anything.
Build with Next.js, QR code, print CSS
Data and maps
Dose Spacer: enter real meal times, get dose times that respect the leaflet
A caregiver types the prescription and when the elder actually eats. The tool applies the minimum gap and the with-food or empty-stomach rule and returns realistic dose times, so a patient who eats at 11 AM and 2 PM isn't dosed an hour apart.
Build with Rules table from drug leaflets, Next.js
iPhone and Android app
One List QR: a sticker on the fridge opens the same medicine list at every hospital
The family keeps one live medicine list. A QR sticker on the fridge and the elder's wallet opens it, so a nurse at a second hospital sees what the first prescribed, and the carer doesn't re-type it at midnight.
Build with PWA, QR sticker, Supabase
