<![CDATA[MLX 90614 Sleep mode]]>Hi Everyone,

I'm a bit embarrassed but I'm struggling to put a MLX90614 into sleep mode using the following command. By all means I'm generally proficient with reading sensors using i2c and reading/altering the memory addresses, but this one action has stumped me for hours.

self.i2c.writeto(0x5a, 0xff)

Basically, the entire message that needs to be translated is
Start 1 0 1 1 0 1 0 W Ack 1 1 1 1 1 1 1 1 Ack 1 1 1 0 1 0 0 Ack P
The first part is the SA_W: 0xb4
The second part is the command: 0xff
The third part is the PEC: 0xE8

Any help would be gladly appreciated. Thank you!
