Huge thanks to all of you who have helped beta test the [2.2.0 release of the Konnected firmware and software](/content/blogs/news/konnected-firmware-2-2-0-beta-now-available/index.html). So far, feedback has been great and we're close to making the 2.2.0 release official.

This week I made a few more improvements to the 2.2.0 branch, and it's [available now for beta testing](https://github.com/konnected-io/konnected-security/tree/nodemcu-firmware-2-2).  **Notable improvements include:**

1. **New!** Support for digital temperature and humidity sensor modules. Now you can monitor the ambient temperature with Konnected and SmartThings* and an inexpensive DHT22 module.  [**Buy one here for only $9.50.**](/content/products/temperature-humidity-sensor-module-am2302-dht22 "Konnected Temperature & Humidity sensor module"/index.html)
2. Better handling of rapid open/close events.  Now, each open/close event will be logged. Previously sometimes only the last state would be logged if a contact opened/closed many times very rapidly.
3. More memory utilization and stability improvements.

Please help us beta test the new firmware so we can quickly promote this to a stable release.

**IMPORTANT:** This release requires an update to the Konnected SmartApps on SmartThings.  I recommend updating the SmartApps _first_ before flashing the new firmware. To update the SmartApps, change the SmartThings Github integration branch for konnected-security to the "nodemcu-firmware-2-2" branch, and then click  _Update from Repo_.

If you're using the new Temperature & Humidity sensor feature, there's also a new Device Handler to install.

To flash your device, use the [Konnected Flash Tool](https://help.konnected.io/support/solutions/articles/32000023470-flashing-new-konnected-firmware-software) to flash the two .bin files [downloaded from here](https://github.com/konnected-io/konnected-security/tree/nodemcu-firmware-2-2/firmware).

* temperature & humidity sensor support for Home Assistant is coming soon

Any updates on supporting temp/humidity in home assistant?

Can you connect a Temperature & Humidity sensor to the Konnected Security panel? If so how do you connect it?

The new firmware seems to be running ok on my DIY boards. I don’t have much experience with the previous version. I just connected a temp-humidity sensor and it picked right up after resetting the module. That is a nice feature and I appreciate you building it. I have a piezo element connected downstairs where the old key pad was for the old system. I see quite a bit of latency on the response of the piezo element keyed off of a door opening and/or closing. Is there a way I can improve that? The latency is the only issue I have noticed at this point.

I flashed my boards to 2.2 and noticed that they are much slower than the previous firmware to poll the devices after a reboot. Is there some code in the beta firmware that is causing this? No other issues besides still trying to get AT to see the devices. Both apps are updated to the 2-2 branch. The temp/humidity sensor handling is a great addition! I plan to use it to monitor the refrigerators and the freezer we have in the garage. Thanks for a great product!
