Hey everyone, I wanted to share my experience in setting up a custom binary sensor using value templates in Home Assistant. I’ve been trying to get this working for a while, and it was a bit of a puzzle, but I finally cracked it!
The Goal: I wanted to create a binary sensor that shows whether my Nest thermostat is online or not, but with custom text instead of the default ‘on’ or ‘off’. I thought it would be helpful for quick glances at the status without having to dive into the details.
The Setup: I added the following configuration to my binary_sensor folder:
yaml
- platform: template
sensors:
nest_thermostat_state:
friendly_name: ‘Thermostat Status’
entity_id: - binary_sensor.entryway_thermostat_online
value_template: >-
{%- if is_state(“binary_sensor.entryway_thermostat_online”, “on”) -%}
Online
{%- else -%}
Offline
{%- endif %}
The Issue: Initially, I was frustrated because the sensor kept showing the default ‘on’ or ‘off’ values instead of my custom text. I thought maybe I was missing something in the configuration or perhaps there was a bug in the template setup.
The Solution: After some digging and testing, I realized that the issue was with how the template was being processed. I needed to ensure that the template was correctly formatted and that there were no syntax errors. Once I fixed the indentation and made sure the template was properly enclosed, everything started working as expected!
The Result: Now, my custom sensor displays ‘Online’ or ‘Offline’ based on the thermostat’s status. It’s much cleaner and easier to read at a glance. I also learned a valuable lesson about the importance of proper YAML formatting and template syntax.
If anyone else is struggling with custom sensors or templates, don’t hesitate to ask for help. The community here is fantastic, and there’s always someone willing to lend a hand!
