Humidity/temperature sensor settings update about ithowifi HOT 9 CLOSED

Thanks for the suggestion, I'll have a look at it (always welcome to put it in a PR as well :))

All values are transmitted, but only in one entity that is added to HA: the fan. Based on the code it also can send discovery messages for temperature and humidity so they are added as an entity, but that doesn't happen right now (with firmware readout).

Ah, I misunderstood what you meant, you are correct, this is a bug!

from ithowifi.

The code transitioned somewhat from first reading out the original sensor directly (that was unstable), providing an alternative sensor that could not be read from by the itho firmware (or could be built into older itho models that did not have the hum sensor option available) to the ability to readout the values directly from the itho firmware.

The first option enables/disables direct readout of the sensor via I2C (original or alternative)
The second option disables the sensor in itho firmware, this is needed if an original sensor is being read via I2C in order to prevent crashes of the itho firmware (only relevant for newer itho models).
The readout of values out of the itho firmware has been added since the latest version and is fully automatic, non invasive and now probably the best option for itho units that have the sensor built in by default. Unless you don't want the itho firmware to react on hum input from the unit itself but you want to measure the values and determine the itho speed, in that case you still could use the first two options.

The warnings about enabling the first option (reading) without enabling the second option (block support in Itho firmware) no longer apply if I've correctly read the discussions, so they can be removed.

The combination of settings thus depends on your itho model, which sensor (original/alternative) you want to use and how you want to read the sensor. Both options are still needed to make this possible.

In MQTT settings, enabling Home Assistant MQTT Discovery only seems to send out a message for the fan even though humidity/temperature

All detected values are automatically transmitted to HA after enabling auto discovery, this (should) include any detected temp / hum values.
In my case it looks like this:

Thanks for the clarification. Looks like I mixed up 'built-in sensor' with 'itho original sensor', as 'built-in' is just any sensor plugged into the board. The options don't explicitly mention this is for I2C readout instead of the (default) firmware readout, which makes it all quite confusing when you have an original sensor which can be read without enabling any of the options.

Is there any reason to still use I2C readout with an original sensor and when you only want the data / the box is allowed to react to humidity changes? If not, perhaps it would be better to change to two simple questions and adjust the settings based on that:

• Which type of sensor do you have: no sensor, itho original or alternative?
• Do you want the box to react to humidity changes? (right now only required in case question 1 is answered with 'itho original', perhaps also for alternative if #23 is implemented)

That allows you to keep the options shown to users the same regardless of model/hardware, but have a different implementation. Based on the answers you could then set the actual options:

This doesn't allow you to disable readout completely but if a sensor is installed I see no reason to do so. Also assuming people don't plug an original sensor in to an older itho box :)

All detected values are automatically transmitted to HA after enabling auto discovery, this (should) include any detected temp / hum values.

All values are transmitted, but only in one entity that is added to HA: the fan. Based on the code it also can send discovery messages for temperature and humidity so they are added as an entity, but that doesn't happen right now (with firmware readout).

Thinking about it a bit longer, probably I could bring it down to just one setting:
if sensor readout is turned on:
if itho HW version = 25 or 27 & original sensor => disable sensor support in the itho firmware
otherwise only activate sensor readout

from ithowifi.

If you can automatically detect the sensor that's plugged in and whether they're supported in firmware, you could indeed only show a setting to disable firmware support for the original sensor + fw that support it. That sounds tricky though, since as I understand it you can only check on power on and you need to know whether or not you get a sensor readout both via firmware and via I2C?

All requests are currently also done through I2C so that's no difference. How to error handle faulty readouts etc. is indeed the most important thing to work out.

issue should be solved with 7502b35
Please test if this is working as expected

from ithowifi.

Home Assistant immediately picked up the humidity and temperature after updating, so it appears to be working!

Updated setting also looks like an improvement, that was a quick update, thanks!

Great! Thanks for creating this issue and for the testing!
