I bought a GoControl z-wave thermostat 5 months ago and have already replaced the batteries twice (I don’t have a c-wire). I don’t mind feeding it batteries but the thermostat stops working when the batteries go dead and I only know they’ve died when my house gets really cold and I to go look at the lifeless thermostat. I would like to use WebCoRE to send myself a message when the batteries are low but it appears the stock z-wave DTH doesn’t expose battery level.
Does anyone know if it’s possible to modify the existing DTH to expose battery health? Other than knowing how to go into the IDE and create a DTH from someone else’s code, I know nothing about them. I’m hoping a few lines of code might add that ability to query battery level. Any suggestions are welcome. As a note, I know there is an existing DTH that I can purchase but prefer to not spend the money when I only need battery info.
