I currently us Siemens Logo to measure some temperatures at pipework; I now want addtional points where I measure temperature that are remote from the Logo. I know I can do it with the Logo; but if there some cheapish devices that are node red compatible, but can be used to measure temp. Multiple readings from one device is fine but I have multiple locations I want to read temps. Ethernet is fine......wireless fine also.
Any ideas?
