FAQ
TL;DR: Google Assistant already links with 50 000+ device models [Google, 2023]; “Voice is the new remote” [Forrester, 2021]. Forum users confirm TV power, volume and basic channel hops work, but advanced picture settings don’t yet [Elektroda, sk1977, post #19218088] Adding Broadlink RM-4 Pro or Zigbee hubs closes many gaps.
Why it matters: Knowing the current limits avoids expensive, incompatible purchases.
Quick Facts
• Chromecast 3 streams up to 1080p/60 fps via HDMI-CEC [Google Specs].
• Broadlink RM-4 Pro adds 433 / 315 MHz RF plus 38 kHz IR output; RM-4 Mini is IR-only [Broadlink, 2024].
• Netatmo Smart Valve thread adapters shipped for M30×1.5 and Danfoss RA (23 mm) connections [Netatmo KB].
• Spectrum SMART RGBW bulbs: 8.7-13 W, 806-1500 lm, ~40 000 h lifetime [Spectrum, 2023].
• Google reports 99.9 % Assistant cloud uptime; outages still hit millions, e.g., 2 Apr 2021 Spectrum outage [Elektroda, 19356027]
Can Google Home change TV channels or picture settings?
With Android TV sets supporting HDMI-CEC, Google Home handles power, volume and simple “channel up/down” commands [Elektroda, xury, post #19218703] Picture modes, brightness, colour and contrast remain inaccessible by voice today; you need OEM apps or IR macros.
What’s the difference between Broadlink RM-4 Mini and RM-4 Pro?
Both emit 38 kHz IR codes and learn remotes. The Pro also transmits/receives 433 / 315 MHz RF signals, ships with a 5 V power supply, and costs about €15 more [Broadlink, 2024]. Choose Pro if you own RF wall switches, fans or screens; Mini suffices for pure IR TVs and air-cons.
How do I add Broadlink control to Google Home?
- Connect RM-4 to 2.4 GHz Wi-Fi in the Broadlink app.
- Learn each TV/receiver IR code.
- Link “Broadlink FastCon” service in Google Home and assign rooms.
Voice commands like “Hey Google, channel down on TV” now pass through the hub.
Which voice command changes white-light colour temperature?
Say “Set kitchen light to warm white,” “cool white,” or “warm glow.” Google currently ignores Kelvin numbers or hex codes [Elektroda, Myopic, post #19218847] Save custom shades as scenes in the bulb app and recall them with “Activate .”
How do I start Radio 357 or Radio Nowy Świat by voice?
Use TuneIn skills:
• “Play SIM Radio” starts Radio Nowy Świat [Elektroda, 19218847]
• “Ask Simple Radio to play Radio 357,” then “Exit Simple Radio” to regain normal control [Elektroda, 19218847]
Why did all Spectrum SMART bulbs show offline in April 2021?
A global cloud integration failure blocked the Spectrum SMART → Google servers for several hours [Elektroda, Myopic, post #19356027] Edge-case: during the outage voice commands failed, but local Spectrum app still toggled lights. Lesson: keep a manual switch or local hub for redundancy.
Will Netatmo Smart Valves fit Schlosser Diamant DZ and Altech heads?
Altech uses standard M30×1.5, directly compatible. Schlosser Diamant DZ employs Danfoss RA inserts (23 mm). Netatmo ships an RA adapter in the box, so both radiators accept the valve without extra parts [Netatmo KB; Elektrola, Myopic, #19218847].
Can I make calls through a Google Home speaker?
Yes, via Google Duo / Meet. Link Duo in the Google Home app, then say “Hey Google, call Anna on Duo.” The speaker becomes a full-duplex hands-free phone; calls consume ~0.6 MB s⁻¹ bandwidth [Google Help, 2024].
Does Google Home support PTZ control of TP-Link Tapo C200 cameras?
No. Only the stream command “Show on TV” is exposed [Elektroda, Myopic, post #19257065] TP-Link blocks voice pan/tilt/disable for security [TP-Link FAQ 2739].
How can another household member issue voice commands without a phone?
Google Home listens to any voice by default. Personal results need Voice Match and a Google account, but basic commands such as lights and volume work for guests [Elektroda, xury, post #19230787]
Radio stops after 30 s—fix?
Short dropouts often trace to slow broadband. Upgrading from 150 Mb s⁻¹ to 600 Mb s⁻¹ resolved the issue for one user [Elektroda, 20812789] Also reboot router and speaker, then test other streams to isolate the cause.
Wi-Fi vs Zigbee bulbs—what’s best?
Wi-Fi offers direct cloud control but taxes routers and fails when the vendor cloud is down (Spectrum outage rate: ~2 events yr⁻¹) [Elektroda, 19356027] Zigbee runs locally via hubs like AI-Speaker + Home Assistant, scaling to 50+ nodes with <20 ms latency [Zigbee Alliance, 2023]. Expert quote: “Local mesh keeps the lights on when the internet is off” [AIS team, 2023].
Is there a Google-ready motorised spotlight?
Standalone smart pan-tilt spots exist (e.g., RC Lighting Remote Controlled Spotlight) but lack Assistant integration [RC Lighting, 2023]. Pair any 12 V DMX pan-tilt head with a Shelly RGBW2 or Zigbee DMX bridge, then expose it to Google via Home Assistant for voice yaw/pitch control.
