Hi, I have some item numbers where some wireless sensors give me back the battery voltage in millivolt. So i got 3100 for 3,1 volt. Is there a way to format the voltage directly into the item without using a rule, using a trasformation?
Thanks
Marco
Maybe. I think it depends if the binding in question supports transforms, many do but some don’t.
here’s an example which reduces returned value by 3:
item Number Temperature_1249 “Kitchen 12/49 [%.1f °C]” (House,Kitchen,All_Temperature,Node12,log) {mqtt="<[OH2MQTT:home/rfm_gw/nb/node12/dev49:state:JS(minus3.js)]"}
Transform minus3.js contains
(function(i){ return i -3.0; })(input)
