"Error sending switch command, check device/hardware !"
-
I have a mysensors relay node that I have been using acting very oddly. If I unplug the node and plug it back it it will work as it should a few times (on/off). After I cycle it about 3 times it stops working and instead I get the following error "Error sending switch command, check device/hardware !"
If I unplug it, it works again about 3 times then right back into this pattern of behavior. Any ideas what to do with this?
The sketch is unmodified from mysensors. I thought it may be a range issue so I took the gateway close to the lamp and I have the same issue.

The relay might use too much power, causing a voltage dip that prevents the mcu from working correctly. Which capacitors and what power supply are you using? (How to ask for help)

Adding a capacitor to the radio is what I needed to do! Made all the difference in the world!
