I'd like to start measuring my home's indoor and outdoor
temperature and import the readings into PH. Can anyone
recommend today's best options for accurate (+/-1 df)
temperature devices and what interface would be best?
Hard wired or wireless will work for my application.
FYI - plug and play works best for me but I'm willing to
learn whatever if needed. Thanks

Jimmy,
I would think 1-wire would be your best bet. PowerHome has a 1-wire controller and you should be able to get a 1-wire controller
that is either serial or USB (it must be able to create a serial port on your PowerHome machine). This is of course a hard-wired
device but you can have multiple 1-wire devices on a daisy-chain.
Another option if you're technically inclined would be to use the "Generic Serial/Arduino" controller. This allows you to connect
an arduino with temperature sensors or inputs/outputs, etc. The problem with this though is that it's hardwired and so the arduino
typically needs to be close to the PowerHome machine but the temperature sensors could be remote.
Last option would be to use the MQTT controller. You should be able to buy remote (and wireless) temperature sensors that support
MQTT and get that data into PowerHome. You can also use an ESP8266 or NodeMCU and essentially roll your own for very cheap using
the publicly available libraries.
Hope this gives you some potential ideas.
Dave.

Dave,
Thanks for the guidance. I've read the forum posts on
1-wire and I think that's what I'll start out with. The
Arduino is interesting since it can also handle DI's but
that will be a longer term project for me.
Jimmy

There is the Shelly H&T which uses WiFi and supports MQTT. ~$29
