Model: Tapo H200  
Hardware Version:
Firmware Version:

I've noticeably had trouble with Tapo since i set it up. Mainly round the buttons used for turning bulbs on and off. I've noticed that some of the buttons (S200b) have a terrible RSSI number, so i thought i'd test trying to reduce it. I've moved the H200 hub 5cm away from the button, yet i have an signal interference RSSI of -123 (strength is -21), which explains why sometimes when pressing the button the bulb goes on AND off immediately. There clearly isn't interference if they're 5cm apart with nothing in-between them.

 

I also have another button 5ft across the hall which has -0 RSSI and both in direct sight of the H200 hub, which doesn't make any sense.

 

I've connected my H200 to IoT on my Deco mesh router so ensure it gets the best possible (and prioritized) 2.4gz connection (which it does) and i've tired using Ethernet too, but i get the same results. 

 

All firmware is up to date. Does anyone have any ideas what's going on with this?

  @th255,

This is definitely strange. The button and the hub will communicate using a sub-ghz frequency, which should provide better range and reduced interference compared to Wi-Fi.

The RSSI is concerningly low, with a -123dB usually meaning that the device is essentially unable to connect. Looking at my S200D, which is two rooms away from its connected hub, shows an RSSI of -52

 

With the devices being that close, I suppose that the button could technically fall in a deadzone of the sub-ghz signal, but it is rare.

 

Do you have the hub and button setup in a place where electrical interference could be a factor? Such as being on top of a router or surrounded by other wireless devices?

 

Have you attempted to reset and re-add the device to the hub?

In addition to this I've noticed that the RSSI only registers if the button has recently been pressed, so upon further investigation I can see all my buttons have bad RSSI regardless of where the hub is in the house. I've moved it to various locations, close and further away from the buttons.

 

I've removed a button and added again, but with no improvement. 

 

In a world where many, many devices use 2.4ghz why on earth has Tapo decided to make it's devices useless if there is anything else on the same frequency. It's unrealistic to expect me to remove smart tvs, Bluetooth key boards, mice, etc, etc when they all work fine using this frequency. I've said before, but if i knew how bad Tapo was i would never have invested so much money in to it.
