You missed the section in the first post that states you need to use either the eControl or IHC apps to configure the RM device.
The new devices can not be used with the older apps, because the older apps have not been updated to recognized them (forcing the use of the broadlink app) and the broadlink app locks the devices to cloud only control.
Short answer: No.
Long Answer: Maybe. There are reports that the RM4 devices that have been locked by the broadlink app CAN be unlocked, but the procedure is finicky and, unlike the older devices, you can not use the manufacturers app simultaneously with third party apps.
The procedure is:
- Factory reset the RM4 device.
a) Use a paperclip/pin/sim tool to press and hold the reset button.
b) Continue to hold the reset button until the status LED blinks continuously, then release the reset button.
c) Allow the unit a few seconds to settle - Connect the RM4 device to your network
a) Run the broadlink app and use it to discover the RM4 device and connect it to your network.
b) Once the broadlink app indicates that the RM4 device has been connected to your network, STOP. Force close the broadlink app. If you continue past this point, the app will lock the device. - Attempt to discover the RM4 device with the broadlink device manager app. (use version 0.44 or greater) The device page will show the RM4 device and it's status.
If the device is showing as "(UNUSABLE - CLOUD LOCKED)" then the procedure failed. You can try the procedure again, only force closing the broadlink app slightly earlier in the connection process.
If the process succeeds, the device will still show "(Unsupported device)", but we can deal with that once we determine if the device can in fact be unlocked.
Ultimately, If you can send your unit back, I would do so. You can still get the older RM2 and RM3 devices that work perfectly well... And you don't need to fight with them to get them to work.
