Measure
SMASH
Automated reminder functions activated on pill monitoring device, motivational text messages, at home BP monitoring SMASH Arm: Auditory and visual reminders are active on Pill device will alert subject each time their medication dose is due. Pill device will transmit dose taken time stamps to researchers. Text message the following morning with tailored motivational messages that reflect the medication dose adherence from the preceding day. Subjects will monitor their BP at home at least every third day using Bluetooth monitor linked to smartphone to transmit encrypted readings to researchers.
Enhanced SC
No reminder functions on the pill monitoring device, attention control text messages Enhanced SC Arm: Auditory and visual reminders are inactive on Pill device. Pill device will transmit dose taken times to researchers. Healthy lifestyle test messages as attention control.

SECONDARY outcome

Timeframe: Month 6 of intervention period and at month 6 and 12 of follow-up period.

24-hr ABP BP average SBP to (\< 130/80 mmHg) - 0 participants with this data reported. Our technology team changed half way through the trial and our ability to use the 24 hour ambulatory monitors code that was built within our institution and transfer it to use with the external data team was unsuccessful.
