Rather than having text-based HA sensors, can you change them to (for example) MQTT sensors? That way you can have lights as actual light entities and appear with the globe icon, and click it to turn it off and on (assuming you can communicate back to the devices).
So rather than using the “sensor node”, publish a message with an “mqtt-out node”, and then this is received by the MQTT sensor. And remember to set the “retain” flag so HA knows the state after a restart.
Alternatively if you instead use a “binary sensor node” I would think sending “on/off” in English should translate it to your language - but I only know English so I’m not 100% sure. The limitation of this approach is everything is just a binary sensor showing you whether it’s on or off, and cannot be interacted with.
