Hello,
I am trying to build a device that tells me when my wood pellets (biomass boiler) a running low in the hopper. I have made a device which beeps when the distance between the roof of the hopper and the top of the pellets exceeds a set distance. I can connect that buzzer output to a relay to give me a signal. I need a device that will connect to Home Assistant that will accept wired NO or NC input so the system can email me to tell me the pellets are running low.
Anybody have any cost effective solutions for this? Iām in the UK.
Thanks in advance
ESPHome maybe, just detect the binary status of an input and do whatever you want with that 0/1,

Definitely ESPHome. I have not watched this video but it has good feedback in the comments. There are plenty more tutorials:
