Thx. Looks almost ok.

Pls put the global vars in a struct to solve possible duplications.

Hey,

I assume that this was what you had in mind about all the global variables ? If you also would prefer to also have the followings in the struct just let me know.

bool pmsa003i_type = false; bool pmsa003i_ready = false; uint8_t warmup_counter; // count for warmup

Also, while looking thru other sensor, I notice that the xsns_18_pms5003.ino could also benefits from using a similar struct. I won't touch it in this PR, but it might be worth a look too at some point

Yeah I like to have them all in a struct but then do not call it data as being the most obvious variable name....

Call it related to your driver like Pmsa003i which is most probably unique within the tasmota global variable world.

Thx.
