  • Shelly Gas - NC/NO electrovalve

    Adding the replies I received from Shelly Support for whomever might be interested.

    Hello support team,

    Can the Shelly Gas be connected to a solenoid electrovalve (the ones with instant shut off) instead of the Shelly Gas Add-on?

    I've attached a picture of the valve and its specifications.

    Thank you in advance.

    Thank you for contacting us!

    In theory, it might work, but we didn't test it out.

    The Shelly Gas is officially compatible with the Shelly Gas Add-on only.

    Thanks a lot for the info. Is Shelly Gas sending a pulse current (an impulse) when shutting off the valve, or it is sending a continuous current to the valve until it receives feedback that it was closed?

    It's a continuous current that is going through. On change and must close, it sends a current impulse that would trigger the valve to close. Remember, Shelly Gas doesn't have relay to do open/close a circuit. We are supporting only the functionality that the device is offering with its add-on manipulator. We cannot guarantee if a solenoid valve would be working well. Thank you for your time!

    So, in theory it might work. I didn't test it because I had already purchased another Tuya sensor (PNI Smart Gas 300 PNI-SHS300) which was designed to work with that type of solenoid valve.

    I'm seeing the same behaviour with DW2 added using ShellyForHass (the custom integration from HACS) and communicating through CoAP. In my case the sensors also report temperatures of 999°C followed by the detected temperature and -1° tilt followed by the correct tilt. I've opened a support case with Shelly and here's their reply after reviewing the debug logs:

    The problem which you are observing with enormous values and after that, they are getting normal that was reported before and right now our devs are working on a solution.

    That is happening on mqtt topic messages.

    We will check what is happening and reach you back with additional information.

    In the meantime, please try using some of the devices without HA and only with Shelly Cloud APP to check if the problem is coming from HA integration.

    Looks like the issue comes from the way DW2 reports values after wake-up, which HA is not able to handle, while the Shelly Cloud APP is able to.

    There is a test firmware which is supposed to fix these issues: 20210820-121213/v1.11.4-rc2-gcc41d4b

    If you want try it: http://<DEVICE_IP>/ota?url=http://repo.shelly.cloud/firmware/rc/SHDW-2.zip

    I've updated my devices with this version and will revert with a status update.
