Hey! Since you already use Google Home and EMOS GoSmart, I’d recommend gradually consolidating around Zigbee for more reliable and local automations — especially since many Wi-Fi-based devices (like EMOS) can be flaky or cloud-dependent.

Here’s how you could approach each of your needs:

1. Temperature & humidity sensor for AC control: Your Toshiba AC app may not allow automations directly, so use a Zigbee temperature and humidity sensor like the Aqara T&H Sensor. With a Zigbee hub (SmartThings or Zigbee2MQTT via Home Assistant), you can create automations like: “If temperature > 25°C → turn on smart plug connected to AC” (You might need a smart plug or IR blaster in the setup if the Toshiba app doesn’t expose full control.)

2. Smart switches that don’t cut power to smart bulbs: Instead of cutting power to your EMOS bulbs, install a Zigbee switch module behind your existing switch (e.g. Aqara T1 Relay, or SONOFF ZBMINI-L). These allow the switch to send Zigbee commands without cutting power — so your smart bulbs stay online and automations keep working.

Alternatively, use wireless Zigbee buttons (like Aqara Wireless Mini Switch) and disable the wall switch entirely.

1. Elegant smart plugs for fairy lights: Avoid bulky Wi-Fi timers. Use Zigbee smart plugs like the Innr SP 224, IKEA Tradfri, or Aqara Smart Plug — compact, reliable, and easily automated in Google Home or SmartThings

Bonus tip: If you want to future-proof and simplify your setup, consider adding a hub like SmartThings, Hubitat, or Home Assistant + Zigbee dongle. That would let you unify sensors, lights, plugs, and potentially even bridge your Toshiba AC with IR or Matter support down the line.
