Email is sent only if first condition is true

Wild · August 13, 2022, 11:34am

esp32 with sensor bme280 sends values to xampp server which records values in mysql database every minute…

Email is sent only when both conditions are true value1 < 25 and value2 < 25

If only second value is true value2 < 25 email is not sent

mark where elseif condition begins

. Please help
