We will be shipping Mysa thermostats between mid and the end of November depending on the time you ordered. Our team is working hard to make the necessary changes to our passive filtering components and we are confident we will have alterations completed, tested and certified within three weeks. The good news is that there is only one other certification test for our product, which has started on October 5th in Vancouver.
Last week, electrical engineer Justin and lead developer Dan went to Boxborough, about an hour outside of Boston, to complete Mysa's first electromagnetic compatibility certification tests. There are seven specific tests involved of which we passed five and marginally failed the two other tests. This will cause a delay in the delivery of the first Mysa thermostats, which we expect to happen between mid and end of November. I have included some more details below about the tests and specifics.
What is EMC testing?
Electromagnetic compatibility (EMC) testing exists to ensure that your electronic or electrical device doesn't emit a large amount of electromagnetic interference (known as radiated and conducted emissions) and that your device continues to function as intended in the presence of several electromagnetic phenomena – think microwaves, cellphones and the like.
There are seven tests of which we passed five and marginally failed the two other tests. We are actively working with FCC (Federal Communications Commission) and our compliance firm to address these issues in the next two weeks. The tests we failed are related to the radiated emissions from our Wi-Fi module at the 2.4 GHz band. The tests showed emissions above the allowable level when the device was broadcasting over Wi-Fi. To fix this issue we will be working with the Wi-Fi module supplier and FCC to bring the emissions within compliance.
