Amazing @Nir , I have been trying to get pool temp for the last 18 months and here it is:
I have been looking around for an inexpensive option for pool temp, but most solutions were very expensive, except for InkBird, which had had some success with HA. I purchased 2x IBS-M1 on the hope of getting a gen 1 version, but I ended up with two gen 2 
I purchased an RTL dongle but couldn’t get that integrated either. Thank you…
I didn’t want to head down the complexity of ssh and the MQTT route, so I combined your two scripts into one python script that returns the value and then setup a simple command_line sensor.
