Hi there!
I’m pretty new to HA and ESPHome and I’m in the process to building a small e-ink dashboard where I want to display room temperatures and have a little icon shown if any of the radiatior thermostats are set to “heat”.
For that purpose I have bought some cheap Hama smart radiatior thermostats. I can see them in HA and they seem to work fine.
I have not yet managed to get any detailed attributes from the thermostat integration in HA, so I cannot set up any sort if binary sensor. But I have also managed to read out their state (which is either “heat” or “off”) from a text_sensor (see image).
Is there a way to do a if condition that compares the value like this for example?
if (id(humidity_bedroom).state.cr_str() === "heat")) {
it.printf(x, y, id(font_icons_tiny), TextAlign::BASELINE_LEFT, ICON_fire);
}
The full code of my YAML is the following:
