Is my router compatible with the Sensi Wi-Fi Thermostat?

The Sensi thermostat uses an 802.11n 2.4 GHz Wi-Fi radio and is compatible with most residential 2.4 GHz Wi-Fi networks. See the Known Incompatible Routers or Access Points table at the bottom of this article to make sure your access point or router has no known compatibility issues with the Sensi thermostat.

 

For best results, ensure that your access point or router has been updated with the latest firmware release. This may also provide better connectivity with your other wireless devices. Click Here or visit the manufacturer's support website for more information.
 

Compatible Network Types

 

  • 802.11b

  • 802.11g

  • 802.11n*

    *802.11n is recommended.

Note: 5GHz and 802.11ac networks are not supported unless dual band capable.


 

Wireless Security Compatibility

 

  • WPA2 (AES)**

  • WPA/WPA2 Mixed Mode (AES and TKIP)

  • WPA (TKIP)

  • WEP (64/128bit - otherwise recognized by 10/26 hexadecimal characters)

  • Open

  • Other combinations may work with Sensi thermostat, but do not conform to recognized wireless standards

    **WPA2 AES is recommended.

 

Note: WPA2 security must use WPA2 Personal or Pre-Shared Key only; WPA2 Enterprise is not currently supported.

 

IP Address Requirements

 

The Sensi thermostat requires a DHCP address assignment. A static IP address cannot be programmed within the Sensi thermostat. However, some residential routers allow DHCP address reservation. If supported by your router’s DHCP server, address reservation can be used to assign your selected local IP address to your thermostat.

 

Dual Band Routers

 

Your Sensi thermostat can be used with dual band access points or routers. Dual band access points or routers broadcast two (or more) wireless networks (SSIDs) – one (or more) in the 2.4GHz band and one (or more) in the 5GHz band. Your Sensi thermostat is only able to connect to wireless networks operating in the 2.4GHz band. If there are wireless networks with the same name (SSID) operating on both the 2.4GHz and 5GHz bands, there may be difficulties experienced with connecting the thermostat to your desired wireless network.
 
We recommend you configure dual band routers (2.4GHz and 5GHz) to have different SSIDs for the two different frequency bands. This allows you to easily connect your faster, higher data rate (streaming) devices on the 5GHz band and keep your lower data rate devices (printers, thermostats, home automation, etc.) on the 2.4GHz bands. Please consult your owner’s manual or visit the manufacturer’s website of your router or access point to determine how to change your wireless network SSIDs, if needed.

 

Technical Router Information

 

Newer router interfaces may have a firmware version check feature built in, however, it is still recommended to verify the latest release on the manufacturer’s website as some earlier releases may incorrectly report no updates available when there is updated firmware available.

Your Sensi thermostat requires IEEE (Legacy) Power Save Polling (PSP or PS Poll). Wi-Fi Certified 802.11n devices should support it, however PSP is not a tested criteria of the Wi-Fi certification for an access point or router. WMM Power Save Polling is a different variation of Power Save Polling and is not compatible with legacy Power Save Polling.

It is recommended to use a ‘C’ or ‘Common’ thermostat wire when available. For thermostat installations where a ‘C’ or ‘Common’ thermostat wire is not available, it is recommended to use an 802.11n 2.4GHz Wi-Fi access point or wireless router that supports IEEE PSP for optimal battery life. 
 
Your Sensi thermostat sends outbound TCP traffic on port 8091 and outbound UDP traffic on port 8092. This traffic needs to be able to navigate any network firewalls, proxies, or filter devices.
 
If your router is provided by your Internet Service Provider, please verify if they support the above requirements and that they do not prevent outbound TCP traffic on port 8091 and outbound UDP traffic on port 8092.
 

Known Incompatible Routers or Access Points

 

Use of the following access points or routers with your Sensi thermostat may result in limited or no Wi-Fi connectivity. A firmware or hardware update may resolve the issue, but in some cases, the access point or router may be incompatible with Sensi thermostat. If you have an incompatible router, you may want to implement a different access point or contact your ISP provider and/or router manufacturer for additional assistance.
