Curtain bot and hub mini - comparing notes on numerous issues
I would appreciate feedback from other users on some issues I have been getting during my first month of Switchbot ownership. I have had a support ticket open virtually from day one and although I love the idea behind these products I am on the verge of sending the whole lot back for a refund.
For reference I have a pair of rod type curtain bots configures as an "open from centre" pair, and a hub mini. I have scheduled routines operated from my Amazon devices.
I am getting:
1) Very frequent connection errors between curtain bots and the hub mini (errors 190 and 161) despite the hub being only 3m from the curtains, in the same room and in direct line of sight.
2) Frequent loss of calibration of the position of the curtain bot on the rail, which usually means that if hits the end stop and just carries on running. There is insufficient friction between the rod and the bot to force the roller to stop unless I clamp it up to maximum (see my other thread).
3) Sometimes one of the bots doesn't move at all but somehow still registers its position as having changed. This usually means that the bot gets stuck on the wrong position and a re-calibration is required to restore function.
4) I have had one instance of the entire system going offline - both bots, and the hub. This required a hardware reset on all three items to restore functionality.
At the moment on average I am having to do some kind of manual intervention every 2 days or so to keep things working, which is not really acceptable for a home automation product.
I have sent numerous bug reports and videos to the Switchbot support (who I have to say are pretty good, even if I am no closer to solving my problems) and I currently have an offer to send these items back for a replacement. At the moment I am using the following workarounds.
1) Clamping the bot to the maximum on the rail to prevent overruns. Early days yet but seems effective even though I am worried that this is going to overload the motor or roller bearings and shorten the life of the bot.
2) In my scenes I am repeating the open and close commands three times. My Alexa routine activates the scene three times with a 15 second gap in between. This means that each time my Alexa routine triggers the hub sends the command 9 times. This means I get a lot of "clicking" at the end of each movement. If this approach proves successful I will tune the number of repetitions down.
If I can get these things to work flawlessly for a whole week I feel that will be a step forward.
Any similar experiences out there?
