So my boiler kicks out every once in awhile leaving us with colder water/no heat in the morning. Basically the boiler tries to fire 3 times and then quits. Looking at the manual there is a Terminals for alarm sensor. Thinking if i hook up a low voltage smartthings sensor to this I could get alerts not sure what kind of sensor to use.
Page 33 of this guide talks about the alarm terminal
Basically I think the Terminal has low voltage ON when boiler is in an error/alarm state. Googled low voltage sensors not sure which one would i need.
