Enhancement: Add support for Si7021 and SHT40 temperature/humidity sensors #1275

Closed Vertikar closed 4 months ago

Vertikar commented 4 months ago

Hey Aaron, I've already got a few of these floating around and would be handy to be able to use these:

https://www.adafruit.com/product/4885

https://www.adafruit.com/product/3251

I think there's sample code for both of them on the Adafruit website.

This should not be a big deal. I can just add the code without having the devices if you want to test them.

aaronwmorris commented 4 months ago

As of #1278 these two sensors should be supported. I have not tested the code, I just used the example code and implemented from that. Barring typos, this is pretty straightforward.

Awesome thanks, I'll give them a test over the next few days

Have updated and can see it trying to grab the temp and humidity, but it seems to have an issue with the humidity:

I had the wrong property name. Fixed in #1282

aaronwmorris commented 4 months ago

I forgot to hit the Merge button. It is merged now.

Vertikar commented 4 months ago

Cool that's sorted now, I'll dig out the Si sensor and test that soon too

May 29 13:32:37 allsky [INFO] MainProcess-27725/Sensor-1 sensor.saferun() [117]: Dew Point: 8.3, Frost Point: 5.1
May 29 13:32:37 allsky [INFO] MainProcess-27725/Sensor-1 tempSensorSht4x.update() [21]: SHT4x - temp: 23.5c, humidity: 38.1%

Where is that temp value exposed to be used in indi-allsky anyway?

aaronwmorris commented 4 months ago

This is a document I still need to write, but the temperature values are available for the Image Labels/Overlay. The data is stored in the available slots according to the config for the sensor. The dew points or temperature may be used for the dew heater controls, as well.

https://github.com/aaronwmorris/indi-allsky/wiki/Image-Labels#user-sensors

I will assume you have Sensor Slot 10 selected, this means the temperature will be in slot 10 and humidity will be in slot 11. The dew and frost points will stored in slot 2 and 3 (slots lower than 10 are system managed).

Vertikar commented 4 months ago

Tested the Si7021 today and its working fine. Will close this off now
