Roku box seems to be turning on multiple Tvs in house
Roku Ultra 4670x
Software version: 11.5.0
Build: 4312
It would appear that when launching my Roku box, it is turning on other Tvs in the house along with the Tv I’m launching on. This is a new behavior, it’s been happening for a little over a week.
The system:
4 Tvs are connected via a dedicated HDMI ethernet extender network. 3 Tvs share a TIVO and Roku box via the network. Each Tv uses a IR Harmony 880 remote, no native remotes are used.
Main TV is LG OLED65W7P in the living room. It is the home of a TIVO Roamio OTA, Roku Ultra 4670x and StarTech ST12MDLAN2K transmitter box. The extender has its own dedicated network. It is not mixed in with the computer LAN. While it has IR capabilities, my IR system has a dedicated wire for a Xantech system that has worked flawlessly for over 20 years. There is no mixing of the IR signal with the StarTech system. LAN on this Tv is connected via ethernet cable. I do not have satellite or cable, it’s all OTA or streaming via Fubo, Prime, Appletv, Netflix and local Plex.
Both the TIVO and Roku boxes go into a 1x2 splitters (Orei UHDS-102) with one leg going directly to the LG TV the other to a Kinivo 3x1 switch (350BN) which feeds the StarTech transmitter. This gives the remote Tvs access to these boxes and can have them playing on multiple Tvs in the house at the same time. 3rd input to the switch is a feed from the security NVR.
Turning on the living room TV will sometimes turn on both the bedroom and family room TV???? Turning on the family room Tv will sometimes turn on the bedroom Tv. So far none of the other Tvs turn on the living room. Living room is the oldest Tv.
Family room has a Sony XBR55X90CH connected to LAN via ethernet cable. Has a StarTech receiver. Turning on this tv turns on the bedroom tv???
Bedroom has a LG 43UM7300AUE connected to LAN via wifi. I’m not a wifi fan, if I can wire it, I will. I couldn’t here. Also has StarTech receiver. Turning on this Tv sometimes turns on the family room tv????
Studio has Vizio D24f-F1 Tv connected to LAN via ethernet. Has a StarTech receiver. It is the stupidest of all the Tvs and had no troubles, doesn’t turn on nor does it turn anything else on. It is usually tuned to a security NVR feed on another HDMI input on the TV. It is used the least.
I also run a Plex server which is the only local app common to all the Tvs. It is mainly watched through the Roku but each Tv has a dedicated app on them.
What I’ve done so far:
I’ve gone through the setting of all the Tvs making sure any devices connections are turned off (they were). Bluetooth is turned off which really doesn’t make any different because all this is happening via IR. The Harmony remotes are older so they don't have any bluetooth capabilities. I’ve done the same for the Plex app on each Tv and the server. I’ve checked both the Roku and TIVO boxes for device connections.
I turned the wifi off on the bedroom Tv. This is the most constant Tv to mysteriously turn on.
I just recently replaced the switch and the Roku splitter but I first noticed the bedroom Tv turning on while I was trouble shooting the old switch & splitter so I don’t believe this is a factor.
Wifi off, bedroom Tv turned on. I think I've got it narrowed down to the Roku box. Also seems to be coming most often from the Sony Tv (newest) in the family room. If I turn on TIVO at that Tv all is well. If I turn on Roku, bedroom LG turns on. Happens more often than not but not 100% of the time. Not coming from LAN, wifi is disabled. Not coming from IR, there is no IR transmitter in the bedroom only a receiver. I don't think they've developed an IR beam that can penetrate walls and go from one end of the house to the other. Has to be coming in via HDMI. I guess the StarTech system does a good job of transmitting the entire HDMI spectrum.
I've gone into the Roku setting and disabled anything doing with remotes and device connections.
Control by mobile apps, Network access is disabled
Device connect, it won’t let me disable Device connect, “Device connect cannot be turned off when these devices are paired to your Roku player *Enhanced Voice Remote”
I don’t know if this is the culprit, I don’t use the native remote very often but for some functions you need it. It hasn’t been an issue until recently. Has there just be a software update?
I'm scratching my head on this one. Any suggestions?
Try disabling HDMI CEC on one of your televisions from their Settings. Then see if the strange behavior affects only those with the CEC still enabled.
It is probably just a matter of isolating which setting or gizmo (splitter, switch, etc) is introducing or causing issue.
Since it is more of a signal that is causing this behavior (by turning on unintended TVs) and the new switches and splitters are exactly the same as the olds ones and experiencing same behavior, I would think either HDMI CEC related, and/or the StarTech setup.
I know you mentioned they are seperate, but have you verified there are no IP conflicts and the connected switch is operating properly. (assuming you are using a managed switch with this setup).
