It would be nice to have the capabilities of Homeseer’s devices page in Home Assistant’s entities view. Until that (ever) happens, the ‘Search entities’ field allows you to quickly cull the herd based on text-matching. The same can be done in the Developer Tools > States view.
The following example isn’t meant to be a perfect substitute for Homeseer’s devices page but simply to demonstrate how you can use templating and the Markdown card to present desired information in a tabular format.
This lists temperature sensors (but the template can be designed to select almost anything):
|Name|Area|State|Last Changed|
|:----|:----|:----:|:----|
{% for e in states.sensor
| selectattr('attributes.device_class', 'eq', 'temperature') -%}
|{{e.name}}|{{area_name('e.entity_id')}}|{{e.state}}|{{e.last_changed.timestamp() | timestamp_local}}|
{% endfor %}
