Introducing WEM3050T


The WEM3050T, released by IAMMETER in August 2023, is a new 3-phase energy meter. It supports both three-phase and split-phase usage, boasting a more compact 2P package similar to the WEM3080.

The WEM3050T has all the functionalities of the WEM3080T, excluding the IAMMETER-cloud service.

Due to the lack of default IAMMETER-cloud service, the WEM3050T is priced more affordable than the WEM3080T.

Who Needs WEM3050T

For those not requiring IAMMETER-cloud, the WEM3050T presents an excellent alternative, offering almost identical features to the WEM3080T, except for the cloud service.

Please note: WEM3050T does not include IAMMETER-cloud by default. However, it can still be used with IAMMETER-cloud for a 6-month trial period. Once this period expires, the data will not be refreshed on the IAMMETER-cloud. To continue using the service, an annual subscription fee will be required.

Price && Subscription Fees

To be frank, the WEM3050T is an excellent choice for non-commercial customers who are new to IAMMETER products and systems, for several reasons:

If you don't require the IAMMETER-cloud service, the WEM3050T saves you the platform service fee directly (it's only two-thirds the price of the WEM3080T-150). It comes with a free trial period of 3-6 months. During this period, you can use the IAMMETER-cloud service without any limitations. If, after trying the IAMMETER-cloud, you discover that it adds significant value (the IAMMETER-cloud can indeed help save more money, a fact that has been verified by numerous customers), you can then choose to extend the service by paying a subscription fee at the end of the free service period. Moreover, by paying just $60, you can secure the complete service for the device's entire lifecycle.


The retail price of WEM3050T is only $119 USD.
