Output Temperature to Simple LCD Modual

Good Afternoon,

I am looking to expand my pool controller project by displaying the pool water temperature on a LCD mounted in the door of the control box. I am currently reading the temperature and displaying it in a Cayenne dashboard however it would be nice to just look at the control box and see the temperature instead of fumbling with my phone near the pool.

Can Cayenne output sensor values to a simple numeric LCD?



Hi @walters,


Are you using an Arduino or a Pi?



Sorry, should have mentioned Raspberry Pi 3

Cayenne can’t natively output to an LCD display (yet) but it is certainly possible if you use the MQTT API. The general idea is you would sent the temp to Cayenne and the LCD at the same time. Have you tried the MQTT API yet?
