Is there some way I can close a contact from ihost with some device be it sonoff or not? I have a design using SMATE2 which senses the pressing of a door bell using pulse mode. The SMATE2 triggers a TX Ultimate sound and lights through ihost, where ihost is the remote gateway. The user then presses the TX ultimate switch 1 which should then trigger a yet to be determined device which closes the contact in a door bell system for 3 seconds which opens the front door. However I am. Not aware of any sonoff or non sonoff device which has a separately operable dry contact which I can trigger for this purpose. Alternatively I could actually use a switchbot or fingerbit to press the contact button on the “dumb” doorbell. However I’m not sure how to trigger a switchbot or fingerbot from ihost. Can ihost send a notification to Google home somehow? If yes then I can use Google home to trigger the switchbot. Any help would be appreciated. ---

Or you can use the 4CHPROR3 for dry contact purposes. If you need one channel product, need to wait for the new product released. > **[SONOFF 4CHR3 & 4CHPROR3 4-gang Wi-Fi Smart Switch with RF Control](https://itead.cc/product/sonoff-4ch-r3-pro-r3/)** > > 【Independently/Mutual Control 4 Devices】Turn on/off the 4 connected devices separately in self-locking mode.

Did that happen or we still do not have some relay with dry contact? Maybe there is some other product which works good with ihost? ---
