 * Two timers - including selectable day and repeat functionality
 * Battery backed Real Time Clock - DS3231
 * Prototype "Green PCB" in production, using naked ESP32 and HC-05 modules 
+* Temperature readout in Celcius or Farenheit
 
 To be implemented 
 --------------------------
-* Temperature readout in Celcius or Farenheit
+* Add 2 external digital inputs, 2 digital outputs, analogue input 433MHz Rx stream, 433MHz Tx stream connections. This would allow external timer units for example, or analogue temeprature demand (which is still only 1 degree resolution).
 * MQTT pub/sub 
 * "fuel gauge" - Integrate pump frequency, assuming a repeatable dose of fuel per pump cycle...
 * Proper 7 day timer with each day settable for at least 2 times (eg morning/evening)
