Battery vs. External power

    • Autor

    Hi!

    I have 2 H&T Plus.

    Both work perfectly when external power is connected. It sends the temperature and humidity nicely every 3 minutes.

    But if I want to use it from battery, it sends very rarely. It takes 2-6 hours before it sends data. In this case the display shows the correct temperature all the time.

    Why is this? What can I do to make it send the data from the battery?

    Thanks for your help.

    In battery mode, the sensor will only wake up when thresholds set under Settings - Sensor Settings- Temperature Threshold, and Humidity Threshold, are reached.

    If the value does not change above this threshold, the H&T plus remains in deeplsleep.

    Saves battery consumption.

    Hi!

    Thank you very much for your reply.

    The program does not allow me to take this limit below 0.5.

    It would be nice if I could lower it to at least 0.2.

    I hope that this can be changed in one of the updates.

    I don't think that a lower value will come here. Even with the first Shelly H&T, 0.5 degrees was the minimum value. Anything else would lead to increased battery consumption and the user would not enjoy it. If you need the values more precisely, it only helps to connect to the power supply, or possibly use Shelly 1/1PM with Temp AddOn and the DHT22.

    If the thresold is at 0.5 the wake up and info transmission is done at +0.6 it's totally unusable to control the heating of a room for example. I doubt that the user will be very happy with that ... especially since shelly are mostly used in home automation. this limitation makes no sense : a wake up at the exact value of the threshold would be a minimum and an option with a warning to check to go below 0.5 would be highly appreciated, maybe at least from an http get command ... Also a wake up every 3 minutes on power supply is useless and less efficient than a wake up on non limited threshold.

    I bought 10 shelly plus h&t and will have to return them unfortunately because of a simple option not implemented and unavoidable ... it's a shame the object looks well designed but the software is not up to the task because of very questionable choices ...

    We buy shelly for their quality of manufacture and their capacities of configuration, and more time passes, more we are restricted by the firmware...

    When in doubt and because I really don't want to send back my 10 shelly plus h&t, would anyone know a way to bypass this counter productive limitation of the threshold ? a custom firmware maybe ?
