I have three water flow meters and an oled display hooked up to an ESP8266 from espeasy. I'm displaying the flow rate for each meter, and I'd also like to display the total. Do I need to harness 'rules' for this? Anyone have any suggestions?

This I will answer for myself (and others) 1) In Tool>Advanced select Rules. 2. add a Generic - Dummy Device named Oled_sum and in the Values section sum1 3. in Rules add: Code: text Expand Select all Copy to clipboard On Clock#Time=All,**:** do TaskValueSet 6,1,[Flow1#Count]+[Flow2#Count]+[Flow3#Count] endon . 4. in the display support add a new line: Code: text Expand Select all Copy to clipboardSUM [Oled_sum#sum1] . 5. be happy if it works .

2. add a "Generic - Dummy Device" named Oled_sum and in the Values section sum1
3. in Rules add:

Code: text Expand Select all Copy to clipboard
On Clock#Time=All,**:** do TaskValueSet 6,1,[Flow1#Count]+[Flow2#Count]+[Flow3#Count] endon
.
4. in the display support add a new line:
Code: text Expand Select all Copy to clipboard
SUM [Oled_sum#sum1]
.
5. be happy if it works .
